Isatopes~of argon (mass peaks ~ ' 36, 38 and 4U a.m.u.); neon (20 a.m.u.) and krypton ~ ' _ (84 a.m.u.) were also registered. Tlte total con- - tent of all argon isotopes was about 150�10-6, neon about 10�10-6 and krypton abouC 0.5� , 10-6. The isotopic composition of argon was very anomalous in comparison with the argon in the earth~s atmosphere. The abundance of "secondary" radiogenic 40Ar is equal to Che total abundance ~ of the primary isotopes 36Ar and 38Ar. � , [Text) Mass spectrometers were included in the complex of scientific in- strument~tion carried by the descent modules of the "Venera-11" and "Ven- = era-1?.." The purpose of the maas spectrometer measurements was a refine- _ ment of data on the chemical composition of the lower atmosphere of Venus with respect to the principal~ componenCs,.measurement ot the content of small atmospheric impurities (especially the co-~tent of inert gases) and~ finally, determination of the isotopic ~~omposition o~ both the principal components (carbon, oxygen, nitrogen) and inert gases. _ Z'he first communication on the results of the mass-spectrometer experiment in the dense Venusian atmosphere ("First Results...," Istomin, et al., 197g) contained data from a speedy analysis only of a part of the col- = lected information, processed using ca].ibrations carried out in advance. - (In the future plans call for carrying out repeated calibrations in the 1 ~ FOR OFFICIAL USE ONLY ~ APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000100070035-5 APPR~VED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000100070035-5 FOR O~FICIAL US~ ONLY laboratory using duplicaCed instrumenCa under conditiona as close as pos- - gible eo rea~. and wiCh mixCUr~s inc~.uding a broader range of c.omponents (waeer~ sulfur, eCc.).} This communication gives ttte reaults of a more complete analysis af Che collected data which is b~sed once again only on Che preflight calibraCiona of the apparatus.

All even working cfcles of tl~u mass spectrometer accamplished a regime of analysis of inert gases with ~n iricreased response. = The mass spectrometers aboard the two descent modules took the first sample at an al~itude of about 23 km and operated until landing took place. The last gas samples were taken by mass spectrometers at an altitude Erom 3 to 1.5 km over the planetary surface. The mass spectrometers aboard the de- scent modules of the "Venera-1.1" and "Venera-12" each took 11 gas samples; a total of 176 mass spectra were: transmitted ~to the earth. These character- ized the chemical atid isotopic composition of the lower atmosphere on Venus. Th~ mass spectra were transmitted and reqistered in analog form. The ion ' current amplifier in the mass s ectrometer had four response scales with amplification factors 1, 10, 10~ and 103. A scale change was accomplished automatically at the mass peak, due to which the real telemetric record of the spectrum has an"illegible" form. Examples of the registered mass - spec~ra are given in Figures 2 and 3 ana are discussed below. Each mass spectrum was preceded by the t~ansmission of �ive control para- meters of the mass spectrometer, which included tlie emissiot~ current of the ion source and the current of the magnetic discharge pump. These con- trol parameters are shown in the spectra in Fig. 2 in the form of charac- - teristic "steps." Both mass specL-rometers were of an identical design insofar as possible and this was true both with respect to the technology of their preparation and tests before installation on the vehicle, and in particular, with re- spect to their electric characteristics. In particular, great attention was devoted to the identity of the instruments with respect to the strengths of the emission currents and the ionizing potential and the retarding poten- tial. The latter determines the mass number resolution of an analyzer of the radio frequency type. The ionizing potential was selected in such a way that in the mass spectra there were no peaks of d~ubly io~ized C02 (peak 22 a.m.u.) and argon (peak 20 a.m.u.). ~ The principal characteristics of the mass spectrometer were as �ollows: Range of mass numbers 11-105 a.m.u.

Mos~ of ~hr. calibrations were carried out using mixtures prepared on the basis of c'c~)~ wi Lh a hi gh degrec: of purity (-~99.998~) ; tihe principal impuritiy within L�tia limits of ~he mentione~ purity was nitrogen. The content of inert gases (Eor the mosti par.t argon) in the initial C02 did not exceed 0.~�10-6 (in vol- ume). The l~rincipal model mixLure was a mixture containing 1.5~ nitrogen, 0.4~ oxy- gen, 175�10'~ argon, and the remainder is COZ with a high purity. The mixture was prepared by means of dilution of C02 with atmospheric air (its composition is given as prepzred). The second used mixture was a mixture with a nitrogen - cont�ent ^-4~. T,he calibra~ions with respect to neon and krypton were carried out using air. It appears that the principal source of systematic errors in mass spectrometer determination of composition of the Venusian atmosphere, whosc resttlts are presented below, is the error in knowledge of tlie comp~sition of model mix- - tures. It appears that an evaluation f10-15~ is optimistic, so t}~at the final , result for the principal sma11 components nitrogen and argon can be encumbered by systematic errors ^'20~. Wi.tt~ respect� to the components which are discovered at the response limit (for. a single sper.trum), such as neon and krypton, the error in their deter- mination is evaluated on a preliminary basis by a value of the order of +100`~ -50~ . These errors will possibly be reduced as a result of future work on analysis _ of t}~e collected data. Results. The principal impurity in the Venusian atmosphere, as indicated by the first mass spectra received, is nitrogen. Its volume concentration is 4.St0.5$. This figure was obtained on the basis of ineasurements of the meas- - ured ~eak wit}i M= 14 and is r.onfirmed by measurements on both vehicles. The - scatter of individual points in the overwhelming majority of cases falls ~aithin t1~e mentioned error. The result for nitrogen is illustrated by the fraqments of the mass spectra in Fig. 2, which compares the mass spectra for the Venusian atmosphere and the model mixture with a nitrogen content of 1.5$, It can be seen tk~at the peak with t~t = 14 (nitrogen) in the spectrum of the Venusian atmosphere has a far greater value than in the spectrum of the cali- bration mixture (it is convenient to compare peaks with M= 14 and 13 the isotopP 13C). : Tt~e nitrogen content cited above in general is also confirmed by measurements of the I.Aak with M= 28. This peak is the sum of the mass peaks of nitrogen t~2+ and the CO+ secondary peak arising as a result of the c9issociative ion- _ ization uy C02 electrons.

The reasons for this are Ueing analyzed. 'I'he concentrations of all other impurities in the Venusian atmosphere, both chemically active gases and vapors, do not exceed several 1lundredths of a percent by volume. Thus, water vapor, chlorine and sul~ur are discovered mass-spec~rometrically almost at the limit of response for one spectrum. Water vapor is manifes~ed in the "excesses" of the peaks with M= 18 and 17 above the values caused by the "normal" isotopic composition of oxygen. Chlorine is discovered in in some mass spectra as a weak peak with M= 35, and sulfur in the form ~ of an "excess" of the mass peak with M= 32, above the value caused by thp ' contribution of 02+ ions in ~he ion source of the instrument due to dissoci- ation with ionization of Co2. Due ro the �act that there were no preliminary calibrations of the mass spectra t~.~z water, chlorine, sulfur and compounds of the latter two, these data mus~ be regarded as very pr.eliminary. A quan- . titative estimate of the content of these small impurities for ~he time being has not been made. The excess in the mass peak ~aith M= 32 can be at- tributed also to the molecular oxygen in the Venusian atmosphere. The presence of sulfur vapor in the Venusian atmosphere is far more probable than the presence of free oxygen. However, in the light of recent chromatographic � measurements by Oyama (1979), according to which, in the lower atmosphere of Venus there was molecular oxygen in a concentration of about 60�10-~, the excess in the mass peak with M= 32 which we registered can be attributed, - with some difficulty, also to free 02. In any case, some identification seems all the more necessary because optical spectrophotometric measurements made simultaneously on the "~enera-11" and "Venera-12" (Moro2, et al., 1979) reveal an exceedingly low upper limit for gaseous sulfur in the lower atmo- sphere of Venus. The mass spectrometer registered a number of inert gases in the Venusian at- mosphere, specifically: three isotopes of argon (36, 3a and 40 a.m.u.), neon (20 a.m.u.) and krypton (84 a.m.u.). The isotopes of argon can be seen clear- ly on the cited fragment of the mass spectrum in Fig. 3. It can be seen that _ the isotopic composition of argon is very "anomalous" in comparison with the argon in the earth`s atmosphere. The abundance of "secondary" (radiogenic) - isotope 40Ar in the Venusian atmosphere is equal to the total abundance of the "primary" isotopes 36Ar and 38Ar. As is well known, in the earth's at- mosphere the isotope 40Ar is 300 times more abundant than the isotope 36Ar. The ratio of abundances of both "primary" argon isotopes in the Venusian atmosphere, on the other hand, is the same as for argon in the earth's at- mosphere. The more precise values for the relative abundances of argon isotopes in - the Venusian atmosphere are as follows 36Ar 42t2; 38Ar 8 t 2; 40Ar 50 t2. 5 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000100070035-5 APPR~VED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000100070035-5 I~'OK Or'CICI.AL USG ONLY '1'h~ tolal content of argon isotopes is estin~a~ed nn a preliminazy basis al: (150 50) �10'~. - 'I't~e cnnteci~ nf the neon isotope (20Ne) is (10-15) �10`~, and krypton g4Kr is (0. 5-0. ~3) ~ 10~'~'. (In the �irst publication ( "~'irst Resu1L-s. . . , " 1979) the krypton content was erroi~eously exaggerated by one order of magnitude.) - In the spec~rum shown in F'ig. 3, in ~.~dition to the mentioned components (argon, neon, lcrypton and ~he secondary peaks of CO and COZ) ~here is a ; group tagged by (Xe~~). This is the xenon introducecl into thc instrument and servine~ as a reference for the mass scale. Measurements of. the total abundance of argon isotopes made aboard the "Ven- era-11" ancl "Venera-12" agree satisfactorily with the data published by Hoffmati, et a1. (1979), obtained aboard the "Pioneer-Venus" vehicle (on a large probe) and agree with the data published by V~n Zahn, e~ 11. (1979), meas~aring ~.he isotopes of argon on the entry vPhicle in this same experiment. For ttie time being we do not understand the absence of mass spectrometer - data on the nitrogen content in the lower atmosphere of Venus (Hoffman, et al., 1979). Our nitrogen data agree well with the r~sult of the first anal- ysis with a gas chromatograph on a large probe, the "Pioneer-t7enus," although ttie authors themselves (Oyama, et al., 1979) consider the third chromato- graphic analysis to be the most reliable. ~ _ A further analysis of the eollected data requires carrying out new series of calibrations of. the remaini.ng instruments and the processing of mass ~ spectra on Zn electronic computer, as a result of which there will be a decrease in the noise interference level. It can be hoped that ~here will be a decrease in the error in determining the absolute abundances of all ` thc mentioned components and there will be refinement of determination of - - the "excesses" of the mass peaks with M= 17, 18 and 32 a.m.u., and also the isotopic composition of the principal components of the Venusian atmo- sphere carbon, oxygen and nitrogen.

(Text] The "5igma" gas chromatograph was installed aboard the descent mod- ule of the "Venera-12" automatic interplanetary station for investigating the cliemical composition of the Venusian atmosphere. The distinguishing , characteristic of the "51gma" chromatograph is the use of a highly sen- sitive ionization detector (with a source of ~-radiation). It is based on the Penning effect in rare gases (Rotin, 1974). The choice of the de- tector to a considerable degree determined the overall structure and met- rological characteristics of the chromatograph.

All the detectior columns, txnd also the inpu~ reducer of the sampling . unit,were placed in a specfal thermostat, who~e temperature in tihe measuring regime was 70f1�. This same thermostat hald electrometiric amplifiers and voltage--frequency converters, which together with a sourc~ of d-c voltage constituted the measuri~?g circuit of the ionization detectors. in connectfon with the high response of the ionization detectors to impurit- ies in the r.urrier-g~s some units in the chromatograph, after carryfng out a cycle of surface calibrations, were sealed in order tio prevent the inflow of contamirlating gases during the s~orage period and testing and fliqht per- iods. ' The program for operation of the "Sigma" chromatograph on the descent mod- ~ ule o� the "Venera-12" automatic interplanetary station included the follow- ' ing operations. Approximately 4 hours prior to entry into the Venusian atmosphere the shut- off devices on the cylinder with the carrier-gas and the gas discharge line were opened, the thermostat for the columns was activated and for a period of four hobrs the chromatograph was scavenged by the carrier-gas. Af- ter entry into the dense layers of the atmosphere, during descent from 65 to 54 km from the planetary surface, the device for taking the samples was unsealed, the shut-off device on the line for the calibration mixture was opened and the analysis control cycle was prepared. At these altitudes the absolute pressure in the Venusian atmosphere was less than 1 kg/cm2. Ac- cordinqly, for a control analysis no sample was taken from the atmosphere, but the carrier-gas with the contaminants present in the instrument was fed for analysis. During descent of the descent module of the "Venera-12" station from an al- titude of 42 km to the moment of landinq there were a total of eight analy- ses of the planetary atmosphere. Fi'fty-four chromatograms were obtained. ` Eighteen of these corresponded to a determinatfon of sulfur compounds and 10 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000100070035-5 APPR~VED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000100070035-5 i 1~01t OI~'I~'IG~AL US~ dNLY 27 Correspdnded to ar~ analysis of ga~es with a low boiling pdint. 13 ~ao�~ 14AMcnoro~~:~t ,tan~vner ~ 411N,~O~Or RQ~dA 15 6ADR dnOAuJOntO/~d ~q ~moJu tri,ennrop 7 ~ ` yIOyI/U ACfM(+uv~ER ~ 11:?OO~t C dR~7t') "~AQN4A ORYI'~ldetl0 _ . o.roM'~OCU fi~mnf t� ~ _ ~ ,me~tM ndt?T~an i A) y~ t nnv 30AJONnr JaAC~�:l~ ~ I ~ 1 a o $ ~rn;cr~e;Du ye~nD~tiel i ~~.8 19 ~ 2n j ~ ~j ~ ~ t ~ ~ ~ , , v ~,v~ nwJm I A; Y~1t Ilnv ~ E ~ b ~ /1!0 AY i y ~ ~ ~ � NOCU/II//~A ~ ~ C c 1 e ~ I i ; ~ 2~ ~ i ~ ` i I , z , r~_,~.... i ' A t y~t Pn4 t- . ~ ~ I 6~oa tnu~ ~UJ.1r 6,N~.~nu.hv 1 ~ M1I ~~3 Z = a ~ I nPa6o MnDai ri m~+�~u u i ~ ~ ~ o ~ nm~'un~ : Je~~a ~~~r ~'d eunwim I . e _ ~ dr~ Do~noo twt , 1 � i Yi cu ~ i. , ~ _ ~ !eoM_vem~~n ~0 L _1 Z r r_...._.._ 7rp�~ntt~iiort 11 I 11 frP~~z~v,,sron --YZ- ~~~rvnM~amnp ~ iC~Y : 1.

The computation method and the results will be pre- - sented in another article. Here, without givfng the derivation, we give the following result: if the vehicle is.situated at an altitude of 15 km, the maximum refraction angle for a ray reaching the level 70 lan is 3�, which gives an increase in range by 160 km for a radius of 6,120 km. Thus, the total distance to the radio horizon is 1,510 km, which within the lim- its of accuracy in our computations coincides well with the mean value in Table 3. Now we will return to Figures 2 and 3. The series of bursts is cut off sharp- ly at 0611 hours. Such a nature of signal changes is attrfbutable most simply specifically to the withdrawal of the source beyond the radio horizon. Thus, three circumstances indicate the position of the source of bursts: coincidence of the energy in the discharge with the known value for terres- - trial lightning; distance to the radio horizon, coinciding with the computed range of the source, and total disappearance of the siqnal, corresponding to its "radio setting." The radio noise bursts indicated in Figures 2 and 3 also made it possible to find a number of other parameters of a Venusian thunderstorm. The struc- ture of the bursts makes it possible to conclude that all the impulses are 32 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000100070035-5 APPR~VED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000100070035-5 rnc~ o~~t~~CIAL U5L ONLY from the same source. t'igure 4 shows a histogr~m o� the pulse coun~ing rate.

Syrnvgtskiy] [Texe] The probleme involved in the prediction of solar chromospheric f lnres are ~xCremely diverae and the prospects for their solution are different. The long-range (up to several months) forecasting of flarea is the most difficult of these probl~ns, for the time being having a1- mose no theoreCical basis. This is attributable to the fact that at the present time we do not have a posaibility of indicating the time and plnce of the appearance of a new aceive region on the sun. Accordingly, it is necessary Co turn Co a search for statiaCical patterna on the basis of the collected information. In solving thie problem for the time being it has not been possible to proceed significantly beyond the construction of synoptic maps and defining of active longitudes. (It should be noted thaC for the time being in our country there are no ob- servatories which with sufficient routineness issue such information, despite the fact that some stations occupied by the sun service could do tliis). Th e most long-range forecast (for several years or the enCire next cycle) is prepared on the basis of highly averaged data. Therefore, the problem of such forecasting is less complex. An appronch having adequate theoretical and experimental basis can be - us ed for short-range (from several hours to one day). This problem dif- f ers from the first very, very substantially. Whereas for Che first prob- - lem (preparing a forecast for a time including the appearance of a new ac tive region), for a short-range forecast we have all the necessary in- formation. Since flares owe their origin to a magnetic field, observa- tional data on the magnetic field and its evolution, and alsa a know- ledge of the flare mechanism r~ake possible the theoretical computation of development of the phenomenon. In addition, for this forecast it is possible to obtain additional information from observations of the structure of an active region (and its changes) in the Fraunhofer lines ~~a ~ K-Ca II and others. This structure is determined by the magnetic field at the level of line formation. 35 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000100070035-5 APPR~VED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000100070035-5 ~Ott d~~'ICIAI, US~ dNLY 5uch in brn~d nuCline~ ig tihe fundnm~nCdl ~~p~nC nf th~ prnbl~m. ~~r ehp timp b~ing eh~ pr~~Cic~1 r~~ulrg l.pgv~ much Cd b~ dpgir~d.

Therefore, in thig case gs we11 it is mos~ imporr.gnt to discriminate from the grent volum~ of informaeion thnt pa'rC of it which ig imporCanC for the prediction of flare~. This is cl~arly a thenreeical problem. With refinement of theory Che range of the neceaenry inforn?ation cgn be broaden- ed, but now it is necessary to combine theory and observations on the - basis of already available theoretical principlea ~nd the practice of ob- ~ervations of the developmettt of ective regions. tn order eo ~dvance further both in tlte forecasting problem and in the theory of flares itself there must be a clearer classification of the basic principles on the basis of which the modern Cheory is developed. It is useful to introduce evaluations of the basic principles of the theory, classifying them as: 1) reliable, 2) probable, 3) possible. The following principle can now be classified as reliable. ~ A solar chromospheric flare is a process of sudden transformation of mag- netic energy into forms which can be dire~tly observed. As is well known, flares occur only in active regions. We do not know of even a single case of a flare in the undisturbed chromosphere. Since this principle is un- _ questionable, it is necessary to adopt another principle which is not less reliable than the preceding one. It is as follows. [See footnoCe) The poCential f ield has the minimum energy among all the fields with a stipulated normal component on the boundary of the region occupied by the field. (This is the well-kno*.m theorem of classical potenCial theory, frequently called the "Thomson principle"). Therefore, the magnetic f ield - of an acCive region in a preflare state cannot be a potential field, that " is, a current-free state. In other words, above the surface of the photo- sphere in a preflare state Chere should be a current which changes its - configuration or inCensity in such a way that the energy of interaction Note: Cases of flares in active regions in the absence of spoCs are known (see SOLAR PHYSICS, Vol 36, pp 403-416, 1974. 36 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000100070035-5 APPR~VED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000100070035-5 rd~ o~r~cinr, us~ orrLx . of the currene with the external fi~ld tng~th~r wiCh ehe ~hnr~ct~ri~eic en- ~rgy df Clie currpnC field ig 1~gg eh~n Che ~um nf eh~ ~drreeponding initial v~~l~~:~.

The most important of theae principles is that the field of an ac- tive region in general differa little from a potential (harmonic) field. ~1 comparison of the energy of flares with the Cotal energy of the ~~gnetic � field of the active region shows that the energy of the magnetic field ex- - ceeds the energy of flares by two or three ordera of magnitude. Therefore, a current of about 1012 A exerts no considerable influenc~ on the general field geometry. A considerably greater current could appreciably distort the potentiul field, but such a currenC, speaking iii general, ahould lead to phenomena two or three orders of magnitude more powerful (which never has been observed). What has been said, obviously, gives only an indirect _ basis for considering the current to be relatively weak and the field to difEer little from a potential field. 37 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000100070035-5 APPR~VED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000100070035-5 ~OR d~I~ICIAL US~ ONLY d r.~ 5 Id 18 ~d ~9 , ~.~~~~J - - sg,~~ ?Ip b _ - ll6 - o id a ~ ~'�i .,,?,~d C?~ '~~vy ' - , ~ ~ 1B ~ =J20 ~ ~ ~ ' I60 70 ~ ~-=7b1 Sd' ~1? . ~..,.i . d 11 ~s U ~~s ,zo ~9 N~ o 0 ~ i ~ ~ b 10 16 .

An extremely important prc~blem is the localiz~tidn and Gonfiguration of the current. This problem for the time being can be solved on the basis of the preceding, probable theory of field quasipotentiality. On its basis it is possible to formulate a geometrical (and topological) theory of roagnetic Eields of active regions. Up to the present Cime this problem has been examined at the level of models: the field has been represented by some number of dipoles or individual spoCs gituaCed in the phoCosphere. AC the same time, the field nf aCtive regions is an example of an extremely com- plexly struceured vecCor field (and gn extremely detail~d measured field); mh~refor~, mddel representations 8o noe make it possible to use the greater pare of ~he field information. The expansion of the field in spherical harmonics used in classical problems , (description of the magnetic and gravitational fields of the earth and pla~- e~s) in this case is ineffeceive. There�ore it is necessary to turn to the general theory of vector fields making it possible to describe the qualita- tive structure of the field (in the sense of its ~o~logical properties), and also to draw basic conclusions concerninq the number and positioninq of s.inqular points in the field. It must be noted that the use of numerical methods in solution of the boun8ary problem arisinc here (Neum~nn problem) is completely necessary, but at the same time it is extremely important to have preliminary information on the singular points which can be obtained from an analysis of the boundary conditions. 3~ FOR OFPICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000100070035-5 APPR~VED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000100070035-5 ~~x n~~ic~nL us~ dNr~Y mhe gen~r~l ~d~a o� a qualitative c~esc~iption ~f vec~~or fi~lri~ wag expr~s~- ' ~d ~b~uti a hunctred ~~~rg ago by A~ Pc~inc~re.

The traditional "Zurich" classification of spot groups is customary and simple, but it does not reflect the real topological field complexity. The introduction and broad use of magnetic field rotation ~MFR), and also use of the ~bsolute maqnetic field (AMF') value instead of spot areas,is extremely rtx~dern and promising. We note that in a three-dimensional case the index of field rotation, determined as the "degree of representation" of the field on a unit sphere nf directions, is not equal Co th~ number of sin- gular points above the photosphere, but is only the difference in the num- ber of positive and negative indices of the singular points. Nowever, it is obvious that generally speakinq there is a correlation between the differ~ ence and the total number, and sin~e tihe flare$ arQ related to field com- plexity, MFR can serve as a characteristic of the flare'activity of groups. - Thus, in addition ta the absolute magnitude of the flux, in essence, the energy characteristic of the field, it is also possible to mention another characteristic reflecting the degree of field complexity. Thus, on the basis of a probabilistic principle of the theory (that concern- inq potentfality) it is possible to indicate the positioninq of sinqular points and find the general fiel8 structure. In a case when ft is possible to discriminate systems of independent magnetic fluxes, a current arises on the "limiting" line of force separating these fluxes. A correlation waa established between the parameters of plasma in the neighborhood of this line and the characteristics af the current layer (S. I. Syrovatskiy, 19?6). 90 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000100070035-5 APPR~VED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000100070035-5 ~OR d~~ICIAL US~ dNLY in p~rticui~r, t'~r paw~rfui flar~g wi~h an en~rgy releage ~f abou~ in~2 erg dn ehe bag3.~ c~~ th~~ry it w~~ pe~gibl~ ob~~in ~h~ Gh~r~~teri~~ic time n~ farm~~idn af.~h~ ~urr~nt lay~r C~�1~~ ~~sl~ h~ur~) ~nc1 ~ gt~~ion- - a~y in~en~i~y ~%B�lOZ7 ~rg/g~~~ beinq released ~or the moat pare in ~h~ regidn d~ the far ultravinl~t. mh~~~ ~h~r~C~erigtic~ m~sti ~vi~~n~~y b~ re- garded ag po~gible.

The Presidium of the USSR Academy of Sciences discussed the activity of the Institute of Oceanology imeni P. P. Shirshov. A report was presented by the institute director, A. S. Monin, Corresponding Member USSR Academ~ - of Sciences. ~port of A. S. Monin The scientific activity of the institute, stated the speaker, is directed to the solution of highly important problems in oceanology as a unified~ - complex science, and also practical problems of great importance to the national economy. Theoretical and experimental investigaCions are being - n~ade on the basis of modern attainments in phyeics, hydromechanics, applied mathem~tics, geology, chemistry and biology. physics of the ocean occupies a key place in the institute's worle. One of the principal events in oceanology during the last 10 years was the dis- covery, by the institute's expeditions, of inesoscale eddies having a dia- meter of several hundred kilometers and penetrating many hundreds of meters into the depth of the ocean. Most of the energy of ocean currents is concentrated in these eddies. Tt~e discovery of these eddies has forced a re-examination of concepts con- _ cerning the field of ocean currents and the task now is learn to predict _ the detailed structure of currenta in the ocean With the influence of eddies taken into account. 42 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000100070035-5 APPR~VED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000100070035-5 ~Ott U~~I~~AL US~ ONLY ~ ::�'l,y~ r � ~ i ~~~~U i .,::.a , s . . ~ }r ~~~~~d ~ri J*{ w1 ~a s't � k A 0x * : ~ ~ ; �q re~~~ ;1 y , r x ~ , S '4t~~ ~ t~l J~ ~ ~ ~ : ~~~f~a ~.a,~ re, fi~t~ . � , . ~ .c' ^,s~. ~ �j~~~ ~ ~ 4~: ~ `y . ~ . ~~~~1~~~~~1~ ~~~I ~-0~ tY ~.r if~ ~4~ ~ ~ I'~~ ~ I ~ I ~~r t~`~: Y ~:'y 7,'~ 4 ~ i fPi ' 8 . k' i:;. 9 { .y',>;~~ T , ' - ~ . - x 41 ~:rr - ~ . . rr?f � The "Chernomor" sealab ensures multiday work of a crew of 4-5 men at depths up td 30 m. At the institute there has be~n conaiderable development of numerical model- - ing of global currents and tides. Studies have been made of nonstationary and long-period movements in the ocean, including effects associated with di�ferent mechaniams of wave excitation, variable ocean depth, the earth's influence, and also taking ittCo account viacoaity and reaonance phenomena. These atudies are being carried out in close collaboration with the inst- iCutes o~ the Siberian Division USSR Academy of Sciences. The geophyaical probes with an increased resolution created at the insti- tute made it possible to detect a well-developed vertical microstructure o~ the ocean. [See: K. N. Fedorov, "Fine Structure of Phyaical Fields in the Ocean," V~STNIK AN SSSR, No 2, 1978.) Extensive experimental studies have been made of internal gravitational wavea. The poasibility of gener- ation o� a fine structure of hydrophyeical �ields in the ocean during the pas~age o� internal Waves has been demonstrated. Investigatiu~s of ocean microstructure are closely assuciated with a study of its small-scale turbulence. The large-scale measurements of the small-scale component of ocean turbulence s~hich have been carried out have led to neW concepts concerning it as being aeak turbulence (With small Reynolds numbers), concentrated in thin extenaive microstructure layers. - 43 FOR OFFICIAL USS ONLY APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000100070035-5 APPR~VED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000100070035-5 ~dit U~F'ICIAL US~ ONLY . 4 ~ ' t'. , A4~4... ~ k tra~ ,,,oi4~7 'f'~~i ~;:i ~ ~``'w~'~~~~Y.

Studies have been carried out for investigating the distribuCion of macro- components and microcomponents of gases, organic matter, the processes of their variability, annual circulation and balance in the waters of the world ocean. Specially synthesized polymer sorbents have been proposed and tested. These are for the extraction of uranium, silver and other trace elements from sea water.

Concepts have been developed concerning the generaCion of movemenC of lithospheric plates by deep processes. Models of processes of thrusting of lithospheric plates und::r island ares and the active margins of con- Cinents have been formulated. Studies have been carried ouC on the paleo- geography of the Phanerozoic. Maps of movement of the conCinents during tt~is period were prep~red. As a result of the investigations carried out by Che biological subdiv- isions of the institute it was possible to ascertain the basic patterns of d~stribution of biological ob~ects in the ocean, the peculiarities of zones with high and low productivity, vertical faunistic zonality, and maximum depths of abyssal Crenches in the ocean. There has been develop- ment of work in a new direction for the institute: study of funcCioning of ocean biosystems and the creaCion of biological productivity in them. New methods have been proposed f~r invesCigaCing biological groups (bac- teria, proCozoa, microzooplankton). Diagrams of the cycling of marter and the absorption of energy in biological systems in pelagic regions of the ocean h~ve been prepared. Specialists have formulated maChematical models of the functioning of biological co~nunities in pelagic regions.

It has formulated scientific recommendations on contending with world- wide coneamination of waters in the seas and oceans, on the development of fisheries, and improvement of navigation. These recommendaCions are ` being used successfully in the national economy. The work of the Institute of Oceanology is being carried out in close collaboration with other instiCutes of the USSR Academy of Sciences, min- istries and departments.

In conclusion, Che speaker told about the difficulties which the inst- itute encounters in its activity. The equipment and producCion base of the institute is inadequaCe for carrying out important and responsible tasks assigned it. The experimenCal-design bureau for oceanological apparatus does not fully ensure Che institute with instruments and equip- - ment for field and laboratory experiments. The technical fac~.lities available to the institute are not always used effectively enough. After the report a communication was presented by Academician Ye. P.

The InsCituCe of Oceanology over Che course of the IABt 10 years has been producing first-class scienCific publicntions An example is rhe multivolume work TIKIIIY OKEAN (Pacific Ocean), which has been nwarded the USSR State Prize (1977). Many of Che published works of'the instituCe gre being Cranslated into foreign languages, evidence of tlieir high internationul authority. I~ grear merit of the instituCe's work is the close relationships wieh acad- emic institutions and ehe insCiCutes of other departments and also its broad internatiottal connections. iJow ever-increasing attention is being devoCed to the exploitation of the mineral resources lying on the floor of the Pacific Ocean (even today 24~ - of all petroleum is produced from the floors of the seas and oceans). Evi- dently, the Institute of Oceanology must intensify research in this direc- cion in order to play a key role not only in the study of sedimentation, but also the resources 'lying on the floors of the seas and oceans. Academician V. Ye. Sokolov. The biological studies of Che Institute of Oceanology are quite well known. The commiasion of the USSR Academy of Sciences Presidium working at the institute (V. Ye. Sokolov was a commis- sivn member and was acquainted with the activity of the biological labor- atories) raised the quesCion as to whether it was legitimate for biolog- ical laboratories to be a parC of the Institute of Oceanology. The joining - together of physicists, chemists, geologists and biologists in a single insCitute is desirable when they carry out smooth complex work in a single direction. The commission drew the conclusion that at the Institute of Oceanology there is such a direction study o~ ecosystems in the ocean and its productivity. However, at the institute it is necessary to reduce classical biological investigations to a minimum and against this back- ground estab lish closer contact with the Division of General Biology. Admiral-Engineer P. G. KoCov.

The InsCitute of Oceanology, despite having inadequaCe Cechnical equipment, is functioning at the level of the leading scientific oceanological inst- itutes of the world. Its success~s are attributable both to Che successful selecCion of personnel and the productiive combination of theoretical and experimental investigationa. . A ma~or undertaking of the institute has been compilation of the 10-volume monograph OKEANOLOGIYA (Oceanology), which.a~fords a full idea concerning the status of the entire sc~.ence of the ocean. Four volumes of Chis mono- graph have already been published. The board of the division assumes that the institute shou~.d be more con- cerned with model laboraCory invesCigations and must carry out more in- tensive work in sealabs. Academician A. Yu. Ishlinskiy. Study of the ocean is a broad field of ap- plications for investigations in the field of inechanics. The motion of water is closely related to the movement of air masses and here there must - ' be specific hydrodynamic and aerodynamic investigations. Close contacts have been established between Che InsCituCe of Oceanology and the Insti- ~ tute of Mechanical Problems and a number of problems in hydrodynamics and acoustics are being solved ~ointly. In the implementation of such investigations under laboratory conditions the Institute of Mechanical Problems can ass~ist the Institute of Oceanology, since it has great ex- perience in constructing the necessary apparatus. Academician A. V. Sidorenko. The InstiCute of Oceanology is carrying out much important work on a broad complex of problems related to the mastery of the world ocean. There is a need for strengthening the material-tech- nical base of the institute, but the available equipment and methods are not being used sufficienCly effectively. 48 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000100070035-5 APPR~VED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000100070035-5 Fnx orr~crEu, us~ otvLY '1'he insCituCe shnu~.d occupy un ncC~.ve posieion in sCudy o~ rhe gheYves.

The prediction of indiv~.dua' phenomena or elements of the sea's regime requires a knowledge of the p�~ocesses transpiring 3n the ocean and atmosphere, their interaction and interrelationship. That is ~ahy the level of development of marine hydrological predictions is depen- dent to a considerable degree on our knowledge in the field of large-scale _ circulation of the atmosphere and successful solution of the problem of caeather forecasting for any parCicular time in advance. A role of more than a litCle importance, if not the bas3.c role in the de- velopment of marine forecasts is played by the availability of data from hydrometeorological observations from the entire surface of the seas and oceans which are of a sufficient degree of accuracy and spatial-temporal discreteness. The lack of such data is a serious impedimenC in the study of physical and other processes transpiring in the waters of the world _ ocean, and accordingly, in the field of development of inethods for mak- ing sea hydrological predictions. Despite the mentioned difficulties, in- vestigations in tha field of marine hydrologicai forecasts are success- fully developing. Generalizations of theoretical and empirical studies based on an analysis of the physical processes transpiring i~ the ocean and making it possible to comprehend the essence of the considered pheno- menon will make it possible to evaluate the level of present-day invest-~ igations in the field of marine forecasts and discern ways to develop _ Chem further, including methods for computing and predicting the thermal structure of the active layer in the ocean. It is this theme to wh~.ch this monograph is devoted. This monograph is the first attempt at generalization of Soviet and for- ~ eign studies on predictions of water temperature in the ocean.

TF~e uncertainty of many parameters entering into the equation~ nf hydro- nnd thermodynamics, such as the coefficienta of turbulent mixing, the roughness parnmeter and others, introduces gdditional difficulties when using theoretical models for practical compuCations. At the present level, the basic methods employed in routine work are phys- icostatisrical meChods. It must be remembered that there is a correlation between the two methods. Applicable to weather forecasCs, N. A. $ngrov wrote: "The framework of the physical model muat rest on some genaralization nf known empirical factors and all the numerous parameters of the model also, as a rule, are aet by Che empirical-statistical meChod... In the second approach to the fore- casting problem requirements on the physical structure of the atmosphere - must be imposed on the stochastic model, alChough in the most general form" [9J. These considerations unquestianably also apply to marine fore- c~sts. The development of the theory of random functions, the developm~nt nf prac- tical procedures for the staCistical analysis of observational data and the accumulation of field data favored the development of physicostatis- _ tical methods. It is noo~ possible to precompute many characteristics of the sea and ocean regime. 52 FOR OFFICIAL IJSE ONLY ~ APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000100070035-5 APPR~VED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000100070035-5 rd~ dri~~ICIAL U5~ nNLY J~m~g [~9~ h~g written ybdut eh~e ~mpiricgl nnture of predicCian df ehermttl ~truCtur~~ t,~evastu ~nd t~e1n [77) ~lgd nnte eh~t the pr~ctic~l uge df Cocnmer- ci~l oc~ttndgr~phy invniv~g ~ cnrr~lntion ~nalyai~ df dif~erene d~C~.

In shnre-rnnge forecasts there are ~;re~t possibilities fnr eh~ use of ineteoroldgicgl forecasts, but these pos- sibiliCies ~~re limiCed. For example, forec~sCs of m~ny meeeoralogical ele- mentg are not prepnred for ehe open regiong of the ~eas and ace~ng (ttir _ humidity, cloud cover, eCc.). Therefore in developing short- ~nd especially long-range predicti4ns an effort is made Co not use weather forecagCs. In nature there is a lag in changes in hydrological elements in comparison with meCeorological elemenCs (for example, sea level in comparison wiCh - the wind, water temperature in comparison wiCh air Cemperature, ~CC.); this lag is used in s~tting the advance time of the forecasts. Since these rime intervals are not always sufficienCly great, it is necessary Co use short-range meteorological forecasts (wittd, air temperaCUre forecasCs) for ittcreasing the advance time of the forecast. In developing methods for long-range hydrological predictions without using a meteorological fore- cast a weather forecast is prepared indirecCly. For example, in preparing ~ a prediction of ice conditions on the basis of the pre,ceding pressure sit- uation in actuality an air temperature forecast is prepared. An important role in the development oE methods for predicting hydrological elements for open regicns of the seas and oceans has been played by long- term observations aC mulCiday st~tions in the oceans and seas, work which _ began in the late 1950's. The so-cailed synchronous surveys, in actuality stretched out over raCher long Cime intervals, did not make it possible to separate temporal and spatial changes in hydrological elemenCS.

In this layer there can be depoaits of petrol- cum and gas ~creened.by aCeep salt slopes. The moaC favorable conditions f.or the formation of such trnp~ are created when the salt plugs are com- _ ~~licuted by overhang~ ("cornices"). Th~ existence of the latter wae con- firmed by deep drilling in some do~nes of the interiluve between the Ural and the Volga, in the Emba region and in the eastern marginal part of the Caspian depression. A petroleum gusher (borehole G-31) was obtained fror~ Triassic deposits beneath an overhang on the Zhanatalap salt dome structure. Taking the above into accounC, the mapping of salt overhangs is acquiring - great f.mporCance in petroleum prospecting. NoC only a detailed sLudy, but also the detection of salt overhangs, is ~ still an extremely complex problem. Uaing seismic prospecting by the re- flected and refracted wavea methoda it is possible Co trace the top of ehe salt only in Che arched parts of the domes. Reflections from the ateep slopes and especially from the lower surface of a salt overhang are dis- criminated extremely rarely and inadequately reliably even when using such complex modifications of seiamic prospecCing as Che controlled re- fracred waves method, directional profiling method, common deep-point method. This served as a basis for inv~stigating the problem of the pos- sibility of using data from gravimetric prospecCing for the prediction of salt overhangs. It is known that the salt domes in the Caspian depression are manifested in the gravitational field by strong minima. For this reason detailed gravi- metric surveys are being made on a large scale at the present time and this is affording broad possibilities for use of the gravitational field 56 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000100070035-5 APPR~VED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000100070035-5 rox nr~tctnL us~ drt~Y tn Hulvin~ mnr~ ~nmplex geologicgl prdbl~m~t ~Cudy of gteep ~tt1C ~lnr~~, tlie d~pth c~l' H~ilt in ehe zdne~ U~Cw~~n ddm~~, the eracing of di~l~cati~n~ tn tliu tlilr.kn~N~ ~f dhpn~ieH nbnv~ Che ~a1t, ~tc.

Computation of the gravitational field from the investigated models of salt domea was accomplished using a"Minsk-32" electronic computer prepar- ed specially for the conditions of the Caspian depression. The gravitation- al effect was co~puted from the deposita above the salt, approximated by recCangular parallelpipeds whose measurements along the direction of the profile increase from 0.25 to 2.5 km wiCh increasing distance from the computed point. The gravit~tional influence of masses at a distance as greaC as 22.5 km was taken into account. The program pravided for a~ump- like density change in a vertical direction. In solving the direct problem it is possible to approxima~e the model by ~~arallelpipeds whose dimensions are not the same in different sectors along the strike. The program makea it possible to compute the gravita- _ tional effect from models of salt domes complicated by overhangs. The direct problem is solved quite quickly. If the model consists of a set of parullelpipeds with identical dimensions along the strike the gravitation- .~1 effect at a hundred points is computed in 10 seconds. 57 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000100070035-5 APPR~VED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000100070035-5 I ~nlt t~~~~CIAL US~ (~NLY YI . � . � '~Y ~ � . . . . . � . . , ~ . . ,]p ]lI ; � . � ~ . . , . ~ , . . � , ~ . , , . � � . � - ~ , � � . . , , � ' ~ . . . r y . ~ ' + ? + + .

In auch a varianC it is impossible to ex- amine a section with sa1C overhangs because for determining the latter it is necessary to stipulate three values of depth~ aC a point. The change in depths in each cycle of approximations is accomplished automatically on the basis of the difference in the values of the interpreted and comput- ed anomalies with use of correlation of anomalies and depths. For a satis- factory selection of a model it is usually necessary to use 7-12 successive approximations. For a profile 100 km in length a total of 3-5 minutes com- puter time is required. - ~ The program provides for the imposing of limitations on th~e change in depths to the top of the salt when selecting the model.

Modern grE~vimeters make it possible eo measure the grnviCaCional field with an a~:curacy ensuring reliable registry of r~nomalies of such an inCensity. However, Che gravity minima caused by Che overhangs are situated under conditions exCremely unfavor~ble for their ~liscrimination. In ehese sectors there are considerable gradienCs of Che r~nomalous field creaeed by salt masses. The intensity of the gravitaCional minimum from the models of salt bodies which we have considered exceeds 20 mgal. The amplitudes of the anomalies over salt dome structures in the Caspian depression frequently exceed this value. ACtempts aC separating the anomalies from the salt overhangs and from the main mass of the sa1C bodies by means of filterins of the total field were unsuccessful. We tested different types of transformations with different - ~rid radii. For example, the radius of the grid when carrying out field transformation by the Andreyev-Griffin method varied from 1 to 4 km. Figure 1 shows anomalies from domes with and withouC overhangs, Cransformed by the An~ireyev-Griffin meChod wiCh a radius of 2 km. These curves do not differ nualitatively. Using anomaly curves computed from models of salt domes complicated by over- hangs we solved inverse problems on a"Minsk-32" computer using the program described above. It was found that if the depths to the top of the salt are ~considered known only in the middle part of the dome arch (outside the over- - hang sectors) a form of the top of the sa1C is selected whose relief is not complicated by overhangs and the gravitational effect with a high degree of ~nccuracy coincides with the initial anomalies. Even with a width of the overhangs up to 3 km the field from the selected model deviates from the initial field by not more than 0.5 mgal, whereas the effect from the over- hangs is 2.5 mgal (Fig. 2). It follows from all this that it is virtually impossible to establish the existence of salt overhangs from the qravita- tionnl field without using additional data. 59 FOR OFFICI~IL USE ONLY APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000100070035-5 APPR~VED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000100070035-5 , ~dit 0~~'ICIAI, US~ QNLY - . ,~,ti~ I ~ ~ r.~ ~ , . , . ~ . ~ ri~ . , . ~ ~ +4~ . ~o~i~~~"~~,,'''/ ~ 1 - n ~ ~ ~ ` r ~ . ~ ~ i -r~ ~ t~ ~ ~ +4~. ~ ~ / ' ~ ~ } ' ~ ? ~ ~11~ �~~...~*'~j~ ~ :4 ? + ~~.~.....F~~*..~ * ~ ~ ~ ~ . ~ ~.~..~...~......':~:'�'~'i~.~.. + + I ~+~2 3 ~4 ~S ~6 . ~ig. 2.

Since seismic investigaCions by the reflected waves method and the common deep point method usually make it possible to map the top of Che sa1C in the arch of the dome, it can be expected that the reflections from it are also traced in the overhar.g zone. This is confirmed by factual materials in the Begaydar Severnyy area. Here drilling has penetrated a salt over- hang in a sector where reflecCions from the top of the salt have been _ traced by aeismic prospecCing by the reflected waves method. It must be emphasized that seismic data for such sectors usually do not give a basis for drawing conclusions concerning the existence of overhangs since the wave field at times corresponding to depths below the top of the salt virtually do not differ from the wave field in the central p~srt of the dome. Cases when it is possible to obtain reflections not only from the upper, but also the lower surface of the overhang (for example, the soutti- - ern slope of the Kusanbay dome) are rare exceptions. _ As a result of this determination of the possibility of tracing the top of the salt in overhang zones by the seismic prospecting method it was pos- sible to solve the inverse problem for anomalies from models of salt domes 60 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000100070035-5 APPR~VED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000100070035-5 ron orrzcr~, us~ orrLY complicn~ed by overhnngs witih rigid deC~rmin~eion nf dep~hs tio the Cop o~ eli~ qulr in ehe nverh~ng zone~.

'I'he naCure of Che considered maxima of residual gnomalies is associated wieh ehe gravitneinnal influence of the deposits above the sa1C, lying - under the salti overhangs. The volume of these rocks, under the condieions ' prevailing in Che Caspian depression, can be considerably greaCer than the - volume of ehe sa1C overhang lying over Chem. This is tl~e reason why the - ampliCudes of the maxima of Che residual anomalies nbserved nver the over- ~ hangs in absolute value considerably exceed the gravitational effect from the salt overhangs. If, as was demonstrated above, it is virtually impos- - sible to discriminate the anomalies f rom salt overhangs, the method for _ detecting gravitarional maxima over overhang zones has been worked out quite well and involves the following. Seismic 3nvestigaCions are made by the common deep-point method. These make it possible to trace the top of the salt in the dome arch up to the steep "bench." The area is covered by a detailed gravimetric survey at a scale of 1:50,000. The gravitational field is interpreted by the selection (trial and error) method with a"Minsk-32" electronic computer using the prograr~ described above. In selecCing the salt model Che depth to the top of the salt, determined by seismic prospecting, is not changed. Curves of Che residual field are analyzed; these show Che differences between the observ- ed and selected anomalies. The presence of maxima of Che residual field over the ma rginal parCs of Che domes is an indicator of the existence of a salt overhang. The reliability of this indicator is dependent to a con- siderable degree on the reliability of seismic data on the structure of the Cop of the salt in the dome arch. Work experience shows that there can be errors of two types which can be the reason for both overlooking overhangs and spurious detection of over- hangs. For example, in the area of the Zhanatalap Vostochnyy structure the use of seismic prospecting did not make it possible to trace the top of the s11t to the edge of the overhang. A salt overhang was penetrated by drilling in a sector where reflections from the top of Che salt were not obtained. Under such conditions the additional use of gravimetric data for predicting a salt overhang does noC give positive results.

M. Avchyan and G. 0. Aksalyan] [Text] An investigation of the dependence of the velocity of propagation of a longitudinal wave vp in rocks on their densiCy d and porosiCy kp is necessary when using geophysical methods for studying deep structure of the earth's crust, breakdown of the geological cross section, interpreta- tion of data from acoustic logging, etc. - This dependence has been represented in analyCical form by different auth- ors [1-10]. For example, N. N. Puzyrev [6J cites the following relationship between vp and d for sandy-clayey and some var3eties of calcareous rocks: vp=6o'-11. V. "t. Berezkin [2], as a result of processing of data on vp and d for sandy- clayey rocks from different boreholes on the Russian platform,obtained a quadratic relationship between these parameters O' = 1.75 + 0.266vp - 0.O15vP. However, B. P. Belikov [lJ notes that there is no general functional rela- _ tionship between vp and O'. Due to its stochastic f orm, I. N. Mikhaylov [4] proposes that use be made of procedures for the statistical processing of data. Thus, available information on the relationship between rocks and their density shows that the investigated dependence ~s different for differ- ent rocks and regions. It should be noted Chat the mentioned investigations were carried out for rocks of platform regions where the influence of inech- anical stresses is caused primarily by geostatic and stratum pressures. In - folded regions the influence of tectonic processes causing the diagenesis = of rocks and a change in their density leads to a considerable decrease in density and a greater range of change in velocity than in platform re- gions [3]. Accordingly, it is of great interest to evaluate the possible relationships between vp and ~ for sedimentary rocks in folded regions, where there are considerable changes in the stressed state of rocks even at short distances. 63 - FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000100070035-5 APPR~VED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000100070035-5 ~ FOR OI~'~ICIAL U5E ONLY 'Che 1.nvesCig~ted ob~ecCs were sedimentary rocks from the zone of the Yer- evano-Ordub~dskiy deep fau1C in Che tierritory of Che Armenian SSR.

Figure l,a shows that rocks with a low densiCy have a caide range of velo- city change.

This ma~e it possible to neglect the change in density from pressure - and construct the dependence af vp on Q'dry for different p(Fig. 3). A comparison of the dependence of vp on O'd~, aC high presaures with the results presented in Figures 1 and 2 makes it possible to postulate that ttie conside~able interval of change in vp despite a constant density is a 66 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000100070035-5 APPR~VED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000100070035-5 1~OIt U~~'ICIAL US~ dNLY r~~u1C df ehe differene ~ere~~ad ~e~te of ehe rdcks.
