Zhezhelevskoe occurrence, Vinickaya region, Kozyatinskiy district, village Zhezhelev
Commercial name: Cardinal Grey GG4
On Zhezhelevskom granite deposit in operation is three granite quarries, two of which are supplied mainly gravel, and the third focuses on the production of decorative stone block. Mining takes place staggered two-step system and separation of the granite monoliths of the overall array is done using black powder combined with classic buroshpurovym way.Attaching directly to field of stone processing plant in which part of the monolithic block made various building elements, as well as facing plates. Due to the low fracture of the granite on the field Zhezhelevskom possible production units having the correct shape and volume of up to 3 cubic meters.
In geology Zhezhelevskoe granite deposit usually attributed to the group of Precambrian crystalline rocks, which also includes migmatites, granodiorites and granites Pegmatoid. Together, these rocks form a so-called Ukrainian crystalline shield. Zhezhelevsky Ukrainian granite has a dark gray color and high, uniform grain. Less commonly zhezhelevsky granite porphyry is large inclusions of feldspar and mafic minerals. A kind of "calling card" of the stone can be considered as the presence of very large clusters of garnet and biotite gneisses xenoliths inclusions that give the breed characteristic patchy and sometimes banded pattern.
Granite Zhezhelevskogo field has good strength characteristics, responds well to polishing and easy to treatment. According to the testimony of control of natural background radiation, zhezhelevsky granite has a first class radioactivity that is intended to be universal and unlimited use in the construction work, including interior decoration.
