7he specific heats of andalusite and sillimanite at temperatures up
'to 120WC were measured by the thermal- analysis method. The specific
heat of serpentine at temperatures between 100 and 5OWC was
determined for the first time. The specific heats of granite, basalt,
-peridotite (52-0/6 serpentization). and serpentinite :zontaining 92-%
.6erpentine were also determined. -Results oMe measurements show..

basic rocks are abnormally high owing to the presence of serpentine.
The heat of dehydration of serpentine measured by thermal analysis
was in agreement with that computed from thermodynamic data (V. Ya.
L.eonidov, GEOKhl).
A new modification of,titanium dioidde (T2029), which is meta-
stable under normal conditions, was, -obtained as a result of an in-
vestigation of the stability of ruU16 under high pressures (40 to 120.kbar)'

.The x-ray density is equal to 4. 35 g1cm 1; the' increase in density at

L. F. Vereshchagin, IFVD).
Methods for the investigation of elastic and electrical properties
of rocks under high pressures have been developed in the section on the
physical properties of rocks of the Institute of Physics of the Earth,
Academy of Sciences USSR. In investigating the velocities of longi-
tudinal and shear elastic waves, as well as the electrical resistivity
and dielectric constant of the rock samples under the pressure of

;minirfturri is shiftea toward lower pressures. Owing to the exponential
dependence of electrical conductivity on temperature, an accurate
'measurement of the, temperature, and especially of its gradient in the
sample, is of - great importance. The errors in the measurement of
the temperature caused by the loss cf. heat through the thermo-
'.couple were evaluated by comparing the differdnce in-measurements
'obtained- using three Pt-PtRh thermocouples of different diameters,
.with their junctions in the high-pressure chamber. Results of

the error for thermocouple s with d0. 3 mm was 40* C (A. B. Slutskiy,

Alkali igneous'rocks. from the Kola Peninsula, having high
i.electrical conductivity and low activation -energy under atmospheric
conditions, exhibit a change in electrical resistivity of one-two
orders of magnitude at pressures up to 20, 000 kg/cm? and tempera-

!electrical resistivity when the pres,sure is increased from the atmos-
pheric pressure to 20, 000 kg/cm the activation energy also de-
:creases from 0.76 to 0.42 ev, and the pre-exponential factor decreases
from 10-4 to 6 x 10-4 ohm-1cm-1. Thus, in alkali rocks the decrease
in electrical resistivity with pressure is the result of a decrease in
the width of the forbidden band. Thus, when computing the distribution
of temperatures with,depth fromi electrical conductivity, it is necessary
to take into account the effect of pressure on the electric conductivity
of rocks (A. T. Bondarenko, IFZ).
In the carbon-nickel system, a new phase of carbon penetration
into nickel may be obtained at pressures of 16-20 kbar and temperaturew
of the order of 1, 500"C. The new phase is represented by elongated.

88% Ni. This product is easily soluble in hydrochloric and nitric

E)iper'ir@ents oh.aillcali basalts at high, temperatures and pressures
between 5-10 kbar in the'presence of water have shown that the
order of crystallization of the,minerals with decreasing temperature
is as follows: n agnetite,'monoclinal pyroxene, plagioclase, garnet,
rand biotite, I'n the range of pressures of 20-25 kbar, the order of
crystallization is as follows: magnetite, monoclinal pyroxene,
.',garnet, and amphib'ole. A simultaneous crystailization of plagioclase
1
and garnet has been observed at a pressure of about 15 kbar. Abrupt
,changes in (@mperature 4nd pressure are instrumental in causing
considerable fractionation of the crys;Zallizing melt. As a result of
@this, it is possible to obtain more acidic derivatives, corresponding
to diorite; grandodiorite, and garnet (Yu. S. Genshaft, V. V.
Nasedkin, Yu., N. Ryabinin, V. P. Petrov, IFZ, IGEM).
At temperatures up to 6700-C, two types of variations of electrical
1@resistivity versus pressure wer.e observed in quartz, microcline,
inepheline, and aegirite as pressure was increased up to a maximum
;of 20, 000 kg/cm2. A 50% decrease in elt-.,ctrical'resistivity of
quartz monocrystals was noted when the -pressure along UE optical
axis was changed.

,at higher temperatures was observed in measurements performed- in
nepheline along the optical axis, in quartz perpendicular to the optical
axis.and in microcline along the cleavage. Only increasing resistivit
-was observed in nephqline at,670*C. . Evidently, the increase in resistivity.,
with pressure is associated with a decreaso in mobility of charge A
carriers (E. Y. Parkhomenko, A. M., Bondarenko, IFZ).

density and the velocities of elastic longitudinal waves in rockb from

resistivity with pressure was attributed to the. high moisture content
of the highly porous rocki (Mi. P. Volarovich, Ye. I. Bayuk, K. P_

Spectral investigations at high pressures were conducted in an

TEXTs The hydrodynamics of pseudd-diluted solid-particle layers-were
investigated at 1-300 kg/cm2 and 2'5-300C with a stoiohionetrio gas mixture
used.for the synthesis of ammonia* Coke particles of good electrical con-
ductivity and metallic needle--'b6_nd lazella -s-haped filinge were used as
solid phase. The critical rate velocity,of the gas.-mixtuxe and the height
of the pseudo-diluted solid-particle layer during the process were deter-
mined. The gas mixture was purified of steam, oil droplets.and other
impurities, and ducted into a vertical, cylindrical high-pressure column
with an inner diameter of 25 mm which contained the solid-partiole,layer.
The mixture was then throttled to atmospheric pressure and its consumption
was measured with a rheometer. The transition of the solid-particle layer
