In Krasnoyarsk region the carbonate onyx cave, marble is found in karst caves and in Climatronic cavernous cavities.
In the South of Krasnoyarsk region there are about 12 caves with carbonate onyx, often called marble. The quality of the stone of some of these caves is not inferior to the best world standards. In the primary occurrence of sinter in the form of stalactites, stalagmites, crusts, draperies, developed on the arches, the walls and the bottom of the grottoes, and galleries, are the characteristic elements of paleolandscape. They determine the attractiveness of the caves and their damage is unacceptable. Only onyx from secondary gravitational deposits (mounds and rubble) can be extracted without compromising the beauty of caves. The most interesting manifestation of onyx carbonate in karst caves are the caves Bolshaya oreshnaya and vladimirovskaya, located in Mansky district.
The manifestation of the "Big Hickory" located in the left side of the valley R. tayezhnyy Badzhey, 3 km East of the village of Hickory. The cave is timed to coincide with the siliceous carbonate conglomerates of the Narva retinue of the lower Arctic age and has a complex shape, gallery-well-grotto type. The total length of the moves more than 14 km, depth up to 120m. The cave formations are represented by cows and, to a lesser extent, stalactites and stalagmites. The figure of the cortical cave onyx is plane-parallel. Stalactites and stalagmites in cross-section have concentric zonal or whimsical pattern formed by thin light brown and brown puffs and groups of puffs. The polished stone is of excellent quality. In the gravitational deposits of the cave there are fragments of stalactites and crusts ranging in size from 10 to 40 cm in diameter. Inferred resources graded onyx in the gravity deposits at the category P3 are estimated at 30 tonnes.
Manifestation "Vladimirskoye" is located on the slope of the right side of the valley of the taiga river Badzhey, 6.5 km East of the village. It is timed to coincide with a cave of complex form of grotto-gallery type, with a total length of 1.8 km and a depth of 80 m, formed in the siliceous-carbonate conglomerates of the Narva retinue of the lower Nordic age. Natechnye formations are mainly represented by cows developed on the walls and bottom of the grottoes and galleries, onyx Color is light brown with a clear parallel-striped pattern. Natural fractures provide the block size from 5х10х10 25х25х35 to see the polished Stone of excellent quality. The resources of an air-conditioned cave onyx in gravitational deposits are estimated at 20 tons in P3 category.
Marble onyx of the second type in the form of a veined bodies performing kollateralny cavernous cavity identified at torgashinskaya cave is the limestone deposits. This Deposit is located at the Northern tip of the man deflection in the northwestern part of the Eastern Sayan and is located in the field of distribution of Torgashin and shakhmatovskaya suites of the lower Cambrian, composing a single carbonate thickness. The total area of distribution of carbonate strata on the watershed of the Yenisei and Bazaikha rivers is about 50 km2. Carbonate strata is composed mostly of limestone with lenses and interbeds of dolomitic limestones and Dolomites with sporadic interbeds of brecciated limestones, siltstones, sandstones. Brecciated limestone cemented by reddish-brown calcareous sandy material. For carbonate rocks is characterized by gray and light gray color, they are massive, fine-grained. Cleavage is rarely shown. The strike of the rocks North-West, with the fall in the North-East at an angle of 40-50º. In torgashinskaya cave Suite Intrusive rocks occur, represented by a rare thin dykes of small extent, the composition of microgabbro to velsicol. Within the limits of carbonate thickness distribution the karst surface and underground cavities containing cave sintering formations and sometimes filled with loose clastic material are widely developed.
Torgashinskaya cave is a Deposit of marble onyx located on the southern edge of the city of Krasnoyarsk, on the Northern slope of the ridge torgashinskogo, in quarries of limestone for the Krasnoyarsk cement plant. The bodies of marble onyx were found on the area of 3,3x2, 5 km. the Deposit was Discovered in 1984 by geologists of the Complex thematic expedition of the Krasnoyarsk Ggeology PGO, but so far it is little known except for Krasnoyarsk geologists and stone lovers. The Deposit is represented by housing bodies of irregular shape marble onyx, the origin of which is due to the filling of fractured structures, which were often subjected to argillization processes, and ancient karst cavities with striped carbonate aggregates. Some researchers consider them to be products of hydrothermal karst, so these rocks are more consistent with the name marble onyx than sintered cave formations. Several vein and vein bodies of marble onyx, which are located within the "Blooming log" quarry, now closed, have been revealed. The two largest veins of the body have sizes 10х10х7 m and 10х5х5 m Dimensions to other known geleobraznye bodies of marble onyx in diameter does not exceed two meters. The total volume of bodies, together with small veins, is estimated at 1.1 thousand m3.
Marble onyx has a monomineral calcite composition. Aragonite and dolomite in these rocks is not detected. Banding is due to the alternation of layers of pure yellowish, yellowish-green calcite with layers of calcite, painted with an admixture of pelitomorphic material-products of argillization of brownish-red, brownish-red color, due to the increased content of iron hydroxides. In some veins onyx is met in the form of nodules. In the center of their observed or fragments of limestone or of calcite crystals. In some nodules, zones of concentric zonal onyx alternate with radial-hex crystals of calcite.
Analysis of different decorative features onyx torgashinskaya cave deposits allows to distinguish among these four textural types: straight-banded, undulating-banded, concentric-zonal banded and spotted. Onyx of the first three types are characterized mainly by a clear pattern and different band widths. Stand out subtly-banded varieties with the width of the color bands from a fraction of a millimeter to 1.5 mm, stripped and 5-10 mm broad-stripped – from 15 to 50 mm. In the last two visually you can see a more subtle rhythm. Widespread Krasnopolskaya difference, often characterised by a natural change in the type of poloschatosti from contacts lived to the center. In striped-spotted onyx, the bands 1-12 mm wide have inflations and constrictions, among which are white, light yellow spots of irregular shape, about 15x25 mm in size.the pattern of rocks depends, among other things, on the direction of the slice. At longitudinal sections of wavy-striped onyx it becomes spotted or concentric zonal.
The banding is also emphasized by different dimensions of crystals of calcite aggregate. The structure of the light-colored strips of fine and fine - grained, comb-and comb-Shestopalova; dark – cryptocrystalline. In some instances, wide strip is formed tusovochnym pink-white calcite.
The decorative nature of the rocks is enhanced by the multicolour of striped and spotted aggregates. The predominant color is red-brown in some varieties and yellow in others. Reddish-brown onyx has many shades from cherry red to orange and pink. Yellow color is mainly represented by light yellow and greenish-yellow shades, less honey. The change in types of poloschatosti change the color intensity from gustokashina to light, almost white.
According to experts of the expedition "Controversiality", conducted a qualitative assessment of samples of marble onyx torgashinskaya cave deposits of the first three varieties of it decorative. The most interesting of the second kind, characterized by clear delicate, often lace pattern and nice color. The stone is almost faultless, although some bands in onyx of the first variety of cavernous. Fracturing in the bodies of marble onyx allows you to remove the defect-free blocks size 10x10h10 cm or more. In some cases, it is possible to select blocks with sizes up to 10x50x50cm. All kinds of onyx marble take good Polish close to the mirror, Shine in plates with thickness up to 1 cm Stone retains integrity when cut into plates with thickness up to 5 mm and further processed.
Geleobraznye identified core body of marble onyx located in a worked out quarry. Onyx was a harmful admixture in the production of cement, so it was poured into dumps, which are likely to be from several hundred to the first thousand tons of this stone. At a low cost is quite possible the organization of its production from the dumps. In contrast to the karst formations of the modern cave (stalactites, stalagmites), core body torgashinskaya cave deposits are not environmental objects.
Carbonate onyx aforementioned fields can be used for the manufacture of artistic stone-cutting and mosaic products, and concursante onyx selectively can be used as jewelry-ornamental material for inserts in clothing accessories: rings, brooches, cufflinks, etc. the Size of the stone allows it to be used for finishing parts of the interiors of public buildings. All varieties of carbonate of onyx, sinter caves of the original form, and druses of calcite and concretely onyx torgashinskaya cave deposits are of interest as a fine collection material.
