L'vov, deciduous species are predominant, but the major part
of them belongs to species preferring warm climate. Neverthe-
less, also narrow-leafed evergreemplante play nere an import-
ant part. The flora of Vvov reflects conditions that are re-
lated to the dry subtropic climate. This is in no way contra-
diotory to the occurrence of elements preferring humidity,
e.g. of Pterocarya. These latter elements only indicate the
presence of some humid phytological areas. Judging from their
lithological characteristics, the rests of plants belong to

in any case they are older than the Conch level. From the
point of view of its overall composition and of its :eco-
logical type, the flora of Llvov is identical with the flora
of the Western Ukraine (Mishin and Dzhurov), but the former
has more species. If compared to Lower Tortonium, all Upper
Tortonian floras point to the climate becoming warmer and
being desiccated. Very significant is a distinct uniform mo-
dification in the climate in Intermediate Miocene of the
Black Sea and Caspian Sea area. It would be natural to con-
clude therefrom that a uniform process of climatic change
embraced bimultanqftq@y Central-Europe and the area just men-
tioned. A&--vmaJysia 6f ihe f1dra of L'vov and ofits position
with respect to the ftragmwkiy level leads to stil.1 more fun;-

of Amvrosivevka (Northern Azov area) are undoubtany the same
proves that their ages are identioal. As, by accepting this
conclusion, it is denied that the latter flora belongs to the
SarmtUn period (this applies also to the flora of Krynka),
it is necessary to reappraise critically all Intermediate and
Upper Hiocanic floras of the southern part of the USSR, which
originally had been*attributed to the "Sarmatlan" age of the

TITLE: On the Age of the Coal-Bearing Sediments of the Dilizhan
District in Armenia (0 vozraste uglenosnykh otlozheniy Di-
lizhanfikogo rayona Armenii)
PERIODICAL: Doklady Akademii nauk SSSR, Vol 124, Nr 2,

ABSTRACT: In the environments of the resort of Dilizhan continental
deposits are strongly developed which contain brown coal
beds of considerable thickness. According to their strati-
graphic position these sediments certainly belong to the
Tertiary, their age, however, has not yet been precisely
determined. According to the well preserved leaf residues
(collected by 0. A. Aslanyan, 1957) from these strata 13 plant
varieties were determined. According to these determinations
the flora complex is mainly represented by evergreen ele-
ments of the tropical and subtropical type. The climate is
supposed to have been hot and dry in this region. The summer-
green forms of Ostrya and Rhamnus are not in contradiction
with this conclusion. They accompany fossil and subtropical

floral elements in a quite usual way. According to its
composition an4he ecological character the Dilizhan brown
coal flora resembles the European Middle-Oligocene florgs
(Refs 6,8). There is a striking similarity between this
flora and the Viddle-Oligocene floras of the Zakavkazlye
(Transcaucasia, Refs 1-4). All floras mentioned are character-
ized from the genetic and ecological point of view by a
strong monotony and indicate an arid and hot climate. Their
species agree in almost all cases. Differences are expressed
only in the quantitative interrelations between the repre-
sentatives of individual genera. Thus, the flora of Dilizhan
brown coal can be placed to the Middle Oligocene. The
occurrence of Eugenia Bogatschevii (Lower Oligocene, Ref 5)
is no reason to regard the Dilizhan flora as being older. This
species has simply a wider vertical distribution as has hi-
therto been assumed. The Lower Oligocene floras do not
contain - apart from rare exceptions - small-leaved xerophy-
tic plants which were found in the Dilizhan flora. Theyreflect
a much more humid climate. 'Moreover, A differentiation of
Card 2/3 climatic conditions in the direction of the latitude becomes

obvious in the Lower Oligocene. A further confirmation of
the Middle-Oligocene age of the Dilizhan flora is the
occurrence of a single species of the chestnut-oak (Dryophyl-
lum curticelense). Its vertical distribution is discussed in
detail. In addition, the author concludes from the above age
determination that the coal formation in the Dilizhan district
(Armenia) and in the Akhaltsikh district (Gruziya) took place
under similar conditions and approximately at the same time,
perhaps somewhat earlier in Armenia. There are 8-referenceso
6 of which are Soviet.

ABSTRACT. Variation in
and in nonmetallic inclusions in the metal

Variation in Nonmetallic Inclusions During the Process of Melting (cont .)
heat tinting was used to determine the nature of sections thereof
It was found that, prior to deoxidation, solidified steel with 0. 02 17o
H contains only oxysulfides of Fe with a small amount of Mn
in solution in the liquid steel. After deoxidation and before pour-
ing, two types of nonmetallic inclusions were found in the steel:
highly dispersed particles of FeS with a little MnS, and droplet
silicates -- chiefly manganese orthosilicates of Ca, containing
more than 107o Ca, more than 101o Si and Mn, and less than 10%
Fe. It is observed that @01 diminished to 0. 0081 in 36GZS steel
at the moment of pouring owing to flotation of the nonmetallic in-
clusions, while in 20 P the figure was only 0. 0 154 O/o. This is to
be explained by the fact that in the second case the steel was not
left in the furnace long enough for uniform distriblition of Si Mn.
Three types of nonmetallic inclusions were found in ladle samp-
lings: highly- dispersed Fe and Mn sulfides, particles of
corundum, droplet silicates, and silicate glass containing corun-
dum crystals, more of the latter being found in 20P than in
36G2S steel. Specimens taken from the finished steel showed
corundum crystal particles, chiefly in the ZOP steel, and
elongated Mn - Al Fe - Ca silicates with MnS in solution or as
Card 2/3 films. The diminution in @03;,4ound to occur durinja the Dour

to 0. 0039 for 20P steel and to 0.0'J389/6 for 36G 2S steel is
explained by the flotation of nonmetallic inclusions out of the liquid
steel in the molds and runner boxes. It is noted that the oxides
and sulfides existing separately in liquid steel, the latter being in
solution, form complex oxysulfides during the cooling of 6-t
ingots and in heating for rolling, all the S being absorbed to form
Mn S.

pp. 12412-1219
TEXT: The methods described in publications (Refs. 1-4) for electrolytio
dissolution of stainless steel and high-cliromium steels for isolating
carbides and nonmetallic inclusions are inapprcpriate. When checking the
method of N. A. Saverina (Ref. 2) N. M. Popova, A. F. Platonova, and
K. P. Leonova (Ref. 5) found that at high current densities a dissolution
of the carbides and a considerable contamination of the anode deposits
occur. The authors of the present paper che ed the methods of Refs. 1
and 2 for the isolation of oxidejinoluston3t steels of the '.)(18149
(1Kh18N9)%iand 1X18H9T (MISN9T)Otypee and also noted that the anode
de-p-o-s-ils were appreciably contaminated. They further studied the
electrolytic method devised by Klinger and Ko3b (Refs. 6,8,- cz, an

of the catholyte and the anclyte as well as the operational conditions.
The most suitable current density was found to be a' 0.03 - 0.05 a/cm2,
if a neutral anolyte with 5@o KCNS t !% sodium citrate f 0.08% A9203 and
catholyte consisting of 51o' sodium oitrate acidified with citric acid to
give a pH = 2-5 - 3 are used in the flow-system. Under these condi!long
a. uniform dissolution of the steel sample is attained and no by.-prcducts
are formed. A good isolation of the carbide fraction is a@:hieved, The
X-ray structure analysis of the carbide deposit of the two steels
mentioned above shows that they consist of (Cr, Fe)23C6 and/or carbides
enriched in titanium. A chemical analysis of the cxiae Inclusions
obtained from an anode deposit of 'Khl8N9 steel which had been treated
with chlorine, shows that mainly S102 and A1203 occur which -Is in
agreement with the results of the vacuum melting., There are 5 figureo

TITLE: The influence of deoxidation on the viscosity of
molten iron
PERIODICAL: Izvestiya vysshikh uchobnykh zavedeniy. Chernaya
metallurgiya, no-5, 1962, 34-36
TEXT: The effect of deoxidation of steel by a deoxidising
element depends to a considerable extent on the velocity of
flotation of products of the deoxidising reaction. Since there
are no direct methods of measuring the velocity of flotation of
non-metallic inclusions from a liquid metal, the authors attempted
to evaluate this velocity from results of chang;s in the kinematic
viscosity of liquid iron during its deoxidation with silicon and
aluminium. The viscosity was determined from the torsional
vibrations of a cylinder filled with the liquid investigated.
The experiments were carried out at 1600 *C with additions of
0.1 and 1.0% Si and 0.5 and 1.026 Al to armco iron, in an
atmosphere of purified helium in a furnace with graphite heating
elements, so as to exclude the possibility of veoxidat�on.

The influence of deoxidation on ... S/148/62/000/005/001/009
E071/E135
In all the experiments addition of the deoxidant resulted first
in an increase of the viscosity, due to heterogenisation of the
liquid metal caused by the formation of deoxidation pro.ducts;
this was followed by a steady decrease in viscosity which
approached its-initial value for pure iron. The time taken to
reach the initial viscosity after the addition of a deoxidant can
serve as a measure of the velocity of flotation of deoxidation
products. The duration of flotation'of products formed on the
addition of 0.5 and 1'/@7 Al was 2-3 minutes. On adding 0.1@`O' Al the
velocity of flotation decreased considerably: the initial
viscosity was not attained after a considerable time (25 minutes).
Addition of l;o Si had a similar effect; on adding 0.1@lo Si the
velocity of flotation is considerable, after about five minutes
the deoxidation products were removed. This confirms that the
deoxidation with large quantities of aluminium is more effective
than deoxidation with silicon or small additions of aluminium.

It is established that the effect of vacuum upon the properties of
objects largely depends on the grain composition of the mixture, the extrusion
pressure and the baking temperature. At low baking temperatures extrusion under
vacuum does not change the porosity of objects. In the presence of a great
amount of coarse fractions in the granular structure vacuum does not show a
noticeable effect on the porosity. An increase in extrusion pressure at the
same vacuum and almost the same granular composition lowers the apparent porosity.
Vacuum shows the greatest effect with medium grain size and a riot very low (not
below 1,600 0C) baking temperature. In these cases the decrease in the apparent

porosity constitutes 5-20 percent and attains values of the order of 4 percent.
The addition of a considerable amount of crude serpentine while using vacuum
yields good results. The effect of extrusion in vacuum on thermal stability is
small. Slag stability is almost always better for vacuum specimens. A diagram
of a vacuum extrusion set-up is given and the method of testing is described.
