Abstract
The Tushkanikhinskoye deposit is confined to the Devonian basalt-bearing rhyolite calcareous-siliceousterrigenous formation, which is represented by sedimentary, volcano-sedimentary, sedimentary-volcanogenic, pyroclastic, volcanic rocks of felsic and basic composition, as well as their subvolcanic equivalents. Felsic volcanogenic rocks show signs of ignimbrites. Primary pyrite-polymetallic ores with an uneven distribution of the main sulfi sphalerite, pyrite, galena, and chalcopyrite have been identified. The presence of collomorphic, framboidal and granoblastic pyrite in the ores, as well as the presence of sedimentary breccia ores with sulfi in clasts and matrix advocates for the hydrothermal-sedimentary origin of the ores. The ore bodies represent destroyed hydrothermal structures, so-called "ore hills".
