was first mentioned in an article by V. 9. Reutnve;kiy
in 1931, 7e. I. Gore no' discoverod rebbles rich In manganese oxide
(pyrolusite and psilomelane) near the Bann and Sukh springs in the Ivanov
mine area and came to certain conclusions as to the metathetic genesis of
the deposits.
In his/ -d7escription of tht, manganese ores of West9rn Siberia, A. A.
Vasil'yev L9 referred to the manganese deposit as eluvial. He felt that this
deposit merited detailed study and prospecting.
Notwithstanding such a favorable report, no proper attention was paid
to it until 1939.
In 1939, while making a gsologicai survey (scale 1:100,000) of the left
bank of the Use, south of -cha Ivanov mine, the author examined these
manganese ore outcroppings and ea'rsblished a close connection between manganese
mineralization, the genesis of which had not been previously determined,
and the-Cambrian limestone horizon containing archaeocyathus, first
discovered by him in the Bann SprlaS area.
. In October 1939, K. V. Radugin visited the Usa manganese deposit. After
cutting several trenches he concluded that the origin of the ore was sedimentary
ana that there were vast resources of carboeaceous ores in this region. In his
article E, RaIlugin made a bold fo.:ecast as to the stratified character of
the ores aa?i the at resources of the Ivance deposit. His a lisle gave an
impetus, in 1940, to prospecting.

Structurally these Cambrian deposits constitute a complex steep antiolinel

The very lowest horizons of carbonaceous depoeite pertaining, in our
opinion, to the :.ore' Cambrian -ware discovered along the Use River near the
Ivanov mine, along the Tummyae River, and in the vicinity of the Petrov Mine.
In the neighborhood of the latter, the chief outcropping was dark grey cccrecly
crystallized marbles. Patches of finely or medium crystallized light marbles
were encountered. Usually their lamination was a distinctive trait, but
sometimes they were eolidly crystallized. Under the microscope they showed
a uniformly granulated structure anri were composed of aggregates of calcite
around Nhich,a small admi.ture of fine quartz grains and flakes of sericite
and chlorite was often observed.
On the eastern slope of the Sekvelass pass, in the direction of the M. Tumuyae
River, dark, finely atra..lfied bituminous marbles were observed. The strata
dipped westward at em angle of 65 - 750. In an easterly direction tbse fdnbly
stratified marbles were replaced by dark grey solidly crystallized marbles,
which in turn eavo we? to light o,ey marbles with a strong rmeil of hydrogen

In this district, a zro:e of disi-.cation runs between the marbles and
the extremely crumpled greGn chlorite strata.
Skirting the Use and tLe Tumuyae rivers, in the center of the anticline,
dark marbled limestones and marbles crop out now and than with doubtful
algae (oncolites). The strike of the strata is to the northwest (340 -36)?.)
the dip is largely eastward at an angle of 7? - 85o.
Mining operations in the westernpart cf the ore-bearing horizon revealed
an eastern subaerial wall of dark limestones. Traces of scouring on these
'rocks have been clearly established in the form of sporadic occurrences of
limeetons conglomerates. Judged by the underlying strata, the development
of these dark marbles and dolour-ttized limestones is Lower Cambria? -m ptoldbly

opposite thn.Tumuyas confluence and forming,aecording to our data, the west side

inaccuracy of such a reference atoms from an erroneous idea of the structure of
the regia, in which the deposit is located.

Stratigrapnioally, tufaceaus sedimentary stratum of heterogeneous
composition occurred transgressively,ebo're the liueatone of archasooyathic
formation. At the bliss of this stratum, directly on the limestone, there
was a bed of pinkish-violet tuff conglomerates, ooneieti.ng of rounded dark
grey limestone Aetritus and porphyry detritus, cemented together by tufaceouc
and argillaeeaas sandstone substances.
The patch of conglomerates attained a width of 1(: to 120 motors. The
direct transgressive pressure of these conglomerates on the archaeocyathio lime-
stone horizons ia, clearly observable from the excellent profiles of the banks of
the Use near the Ivanov mine and of the !oft brvk of the B. Tuauyas (Figorre 2).
Near the mine office it is ?vldent that the bacumLent limestones dip eastward
at an angle of 700 and that the congiomeratee covering them also dip eastward
at an angle of 45 - 500.
Limestone detritus contained in the conglomerates indicates the occurrence
of scouring in the lower horizons of the Middle Cariorian carbonaceous deposits,

whilb the p,nx'thyry detritus may have been brought about in either or two
ways: because of dikes of diabasic porphyries intersecting the limestone,
or because of a completely eroded porphyritic blanket deposit which never
pressed on the limestone of the archaeoojathic formation. Finely laminated
violet tuf. sandstone overlies the conglomerates. These rocks, with an
eest'ard dip at or angle of 75 - 80?, have been traced for 500 to 600 meters
on the left b.a.nk of the B. Tcmuyao River. The apparent width of this patch
of violet tufaceous, calcareous sandstone amounts to 350 - 400 meters. A
microscopic examination of these spe~imene shoved that they consisted
chiefly of fine, acute angled grains of quartz, mica fragments, chlorite
and calcite aggregates, cemented together by a quartz, clayey, brown ferrous
cement. Among the accessory minerals present were zircon and titenomaguetite.
The high content of finely powdered iron obviously accounts for the
violet coloration of these rocks. The red stratum of tuff detrital and
scr'stose rocks described earlier, in all probability, developed in the
middle of the Middle Cambrian, since it overlaysthe limestone characterized
by fauna of the lower horizons of the Middle Cambrian and was, in its turn,
covered by a stratum of greenetone tuff-porphyrite, referred to the upper
parts of the Middle Cambrian

shaped like an irregular ore lens stretching 1,200 meters in a northeasterly
(35?v-00
) direction from the Usr. valley to the Magnetic Mountains with an
average breadth of a'+out 120 meters. The character of the lens toward the
north, where oreless limestone p"oduoee an abrupt change :n the ore horizon
at its meximur,. width, is not very'clear. It is possible that a uiajunctive
dislocation, masked by detritus, runs along the northern border of the ore
body.
The southern continuation of the so-called right-b-nk part of the
deposit, already exnlorcd, is on the left bank of the Use.
In 19'9, oxidized psi.lomelaue ore detritus was found by boring on the
left terrace along the line of the strike of the ore horizon. Farther south,
nlnn.n the elope of the vntorehed ridge tc~?..rd the for
4 kilometers to Azhegol brook, psilomelane ore detritus was^en.euntered
sporadically. Hen.;e, the total observed length of the ore horizon exceeded
5 kilometers. Prospecting in 1941, on the left slope of the Use
valley, brought- to light three ore beds, 750, 200, and 800 metiers
long,, within a distance of' ) kilometers. we must remark that, according to
our reasoning, in the left-bank section of the d6,,osit, embracing the Use
valley and the watershed which has been worn smooth but ;a ccWparativcly
sloping, there is every condition needed for a concentration of rich oxidized
manganese ores suitable for the extraction of ferromanganese.
I
The composition of the left-bank ore body is fairly complicated and, in
spite of the many channels passing through it, not completely explained.
Frequent interstratifications of various types of ore and slightly mineralized
limestones were observed inside this ore body, as well as oompleteiy orelese
light marbles and grey "silicilites" with rare seams of shale. In the
midst of the ore horizon there are dikes of diabasic porphyry, usually stretch-
ing in the same direction as the strike, of the carbcaaceous band. The width
of the dikes is 0.5 to 10 meters.
As we noted earlier, the veotprn c~)nta--t of the ore horizon is winding,
depending on its unccn'ormable pressure on the Lower Cambrian basement marbles.
In various cuttings in the west section of the deposit, light marble-containing
conglomerates were discovered. This layer is composed of'acute-angle] detritus
of black and grey marbles, held together b;; a cement of limestone ane sandstone
and sometimes of concentrated n;an8anese.

of the deposit, earr"ed out by the ZSTU ?arty under the direction of A. S.
Mukhin, and after the mineralogical analysis of the ores snide by A. V. Getseva,
two basic classes of ores have been distinguished -- chlorite carbonates ad
limeetc,neq (mengenooalcites).
Chlorite-carbonate or, as they were called earlier, silico-carbonate ores
are the chief industrial type of ore in this rich deposit. Macroscopically they
suggest field leminatel jasperoid rocks of dolomites shading from dark gray
V, ")lack. Under the microscope they display a finely dispersed and, at
times, oBlitie strur,-". Their chief cc+stituente are carbonates (70 to 85
percent) and chlorite.
At pr,sent, after the prospecting operations on the right-bank section
1. V. Radugin and laid doh ea a basis for proapeotisng, does not .gree with
the facts. Such a theory, without any p.)ssible basis, could impose limits
on the proepucte of the great manganese ore region of the Use.

action of Middle Cambrian limestones with characteristic fauna, proyee the
accuracy of our conclusions an to the monoolinal deposition of the are
horizon on the east side of the Una anticline near its center,
The comparatively rich ores in this class make up the central part of the
ore formation in the right-bank section of the Use deposit. They are bounded
on the west and east by poor limestone ores.
In cutter appearance these limestone ores recall the ordinary dark gro;;
or black limestone. Under the microscope such ores generally consist of
fine round grain of manganocascite with a alight admixture of clayey and
carbonaceous matter. They contain from 3 to 9 percent of manganese and change
gradually into oreless mangeniferous limestone.
In the lower (western) part of the cre-bearing formation sheets of ailico-
argillaceous ;re were isolated by A. S. ~.ikhin. They suggested greenish-grey
shale, brown in places. Under the microscope they consisted of finely
granulated silica, some spiculas of sponge, clayey matter, and varying amounts
of manganocaloite. The manganese content in these ores varied between 5 and 15
percent. and the silica between 40 and 60 percent.
It in interesting that we discovered practically identical clayey
siliceous ores in the Alexandrov Mine region, wh.re they also occur in
the lover part of a Middle Cambrian stratum.
The surface are& of the deposit has a well-developed. zone of oxi'ation,
varying in depth between one or 2 (for clone-,grained nre r :?.n' 10 cetera
(for very crumbling varieties near the tectonic zono).

The right-bank section of the deposit, as shown by prospecting, overlies
the east side of an anticlinal structure. Ite composition permits the
assumption that the praoence of the same ore-beating formation with an
industrial manganese concentration is possible on the west side of the

Chlorite carbonate ores; form the main industrial class in the right-bank
section which has been prospected.
In addition to this comparatively rich class of ore, there are also
limestone ores with a manganese content running between 2 to 3 and 10 percent
(average content 6 percent).
The question of utilizing these poor ores must be raised in co section with
the use of limestone for smelting and for blast furnaces in the Stalin
