THE TALITSA INTRUSIVE MASSIF,
MOLYBDPsNUM-WOLFRAM DTPOSITS
Up to the present, seven molybdenum-wolfram deposits are known to have
been discovered in the Talitsa Massif, but geological prospecting is being
carried out in only three of them. A brief description of the deposits fol-
lows:
Verkhne Slyud~vanka Wolfram Aeposit
This deposit is located in the Ust-Kalmanka Rayon of Altay Kray. ,It
was discovered by the author in 1941. The main mass of the ore body con-
sists of coarse-grained, often drusy quartz, whose color varies from gray to
white. Besides quartz, wolframite is distributed in pockets of ore; scheel-
ite is found together with wolframite in appreciable amounts; fluorite pyrite,
'and chalcopyrite are also present; and in the oxidized zone there is limonite,
malachite, azurite, and tungstite.
Although wolframi~te often coincides with the casings of the veins, giv-
ing the latter a belt-like structure, it is also often disseminated in the
veins without any ,regularity. Fine-grained wolframite prevails in the ores.
I Scheelite is always combined with wolframite and is very rarely found,
separately in the veins which have been surveyed. It permeates the grains of
wolframite by cleavage, or corrodes them. Scheelite is very often encountered
in the ores, although in smaller quantities than wolframite.
The formation of minerals occurred in this order: high-temperature min-
erals were formed first, namely wolfr~mite, tourmaline, coarse-grained quartz
and mica; later,-the sulfides. and fine-grained quartz, as well as scheelite
and fluorite were formed.

The enclosing rocks, particularly biotitic hornstones, are enriched by
tourmaline in the vicinity of the quartizitic veins. Fine micaceous fringes
have formed in the casing veins. The quartzitic dioxites are greisenized.
Mul?chinskoye Molybdenum-Wolfram Deposit
This deposit is located in the Scloneshnoye rayon of Altay Kray, 25
kilometers southeast of the Verkhne Slyudyanka deposit. It was.discovered
in August 1942. In the vicinity of the Mul'chinskoye deposit are found the
Chernukhinskiy and the Aleksandrovskiy deposits, which may be considered as
a single wolframite-molybdenum mining region.
phyries, which coincide with the marginal sections of the intrusion. They
extend in a strip of varying width, which reaches 2 kilometers along'the
Mul'chikha River. Aplite-like granites constitute the summit of Malaya
Rossypnaya mountain and are found among the granite porphyries. P~,.phyry-
like granites ,join the water divide of the Mul'chikha and Kuchikha rivers
and reach the. slopes of Maleyr, Rossypnaya mountain. Toward the south, on
the water divide of the two rivers, they are replaced by consertal biotitic
granites. Veiny rocks, aplites, and pegmatites are very rarely found. Some
quartzitic feldspathic pegmatites contain some wolframite, whose grains at-
tain a length of 5 cm.
scheelite is found in large amounts and often is combined with wolfram-
i.te. In contrast with the Verkhne Slyudyanka deposit, molybdenite is found
in considerable quantities among the ores of the Mul'chinskoye deposit. These
ores also contain arseno-pyrite, pyrite, chalc,pyrite, bismuthine, "eleplek-
tit," muscovite, feldspar, and fluorite. In the zone of oxidation occur
poi+ellite, molybdite, limonite, scorodite, bismutite, and wolfram ochers.
The enclosing rocks have changed to greisen. It is interesting that this
phenomenon occurs more sharply in that section of the Chernukhinskiy deposit,
where the granite porphyries have changed into quartzitic micaceous greisene
over a considerable area.
Kazandinskiy MolybdenummWolfram Deposit
This deposit is located in the mountainous sectc: of Altay xray on the
watex? divide of the Shcheleta River and its first tributary, the Kazanda, and
is 30 km south of Soloneshnoye. It, was discovered in 1944 in the course of
exploratory work conducted by the author. It has been quite thoroughly studied.
The deposit has quartizite accumulations with wolframite and molybdenum.. Over
an 800=m area to the west we determined six quartizitic veins from 6 to 20 cm
in width, having a northwest course of 280o and s vertical dip. The widest
vein in this course stretches over 200 m. The veins contain pypite, tour-
maline? bismuthine, and molybdenite. To the east, on the water divide of the
sources of the T.rishkin and Smordinnoye, quartzitic veins are located in the
main outcrops. They are up to 10 cm wide and contain tourmaline and wolfram-
ite. All the veins are located in aplite-like granites and are coordinated
with a system of fissures. Besides these, a series of quartzitic veins,
which contain bismuthine and scheelite, occur in hornstones, which are lo-
cated to the north of the above-mentioned point.
The mineralogical composition of this deposit differs somewhat from that
of the preceding deposits. The veins are composed of light gray and white
coarse-grained quartz with drusy vacuums and mountain crystal. Mica and feld-
spars sre very rarely found in the quartz. The following minerals are present:
huebnerite, molybdenite, scheelite, bismuthine. The molybenite here has a fine

flaky texture, and bismuth occurs in considerable amounts; dark green tour-
maline is lacking, and black tourmaline is rarely found. Pyrite occurs in
appreciable amounts and chalcopyrite in small amounts. Fluorite has been
found in some places.
In oxidized and very porous ores are found the following: limonite,
,jarosite, bismutite, bismite, gy,.sum, molybdite, wolframite others, and
natural sulfur.
The Talitsa deposit, discovered by M. A. Luppov in 1941, is located on
the right bank of the upper Anuyskaya Talitsa River, 12 km south of the Ka-
zandinskiy deposit. It is a quartzitic accumulation with molybdenit~, hue-
bnerite, fluorite, muscovite, and feldspars.
Karakol'ski.y Molyrtidenum Deposit
This deposit is situated on the eater divide of the Kyzyl-Kalbals,
Uskucha and Malaya Talitsa rivers, 20 km east of the Talitsa deposit. It
was discovered by V. A. Kuznet~ov in 1941, and in 1942-43 it was studied
by the Bashchelakskaya geological survey group of the "Soyuzzolotorazvedka"
Trust.
It is located among splits-like and muscovite granites and hsa quartzi-
tic veins ,'-nd dikes of aplites. The veins consist of gray and light gray
coarse grained druse-like quartz, in spots of which are Pound the following:
molybdenite, scheelite, pyrite, chalcopyrite, powellite, limonite; natural
sulfur, and fine greenish mica. In 1944, we discovered wolframite in ore
slimes, taken Prom the alluvial deposi+,s of the Terta (Uskucha) River and
its tributaries.
