PROSPECTS OF CARBONACEOUS DEPOSITS IN THE CENTRAL PART ZAURALSK ELEVATION ON PRECIOUS AND RARE METALS

摘要

This paper considers the geological structure of the Troitsk area, located in the central part Zauralsk elevation. Particular attention is paid gorodyshchens’k, alexeyev, chulaksay suites potapovsk and komsomol strata within which developed carbonaceous deposits, as well as chebarkulsk-kazbaevsk and gabbro-ultramafic druzhninsk complexes. All of them have been tested for gold, silver, platinum, palladium, tungsten and molybdenum. Found that in the black shale formations gorodyshchens’k suite in the creek Osipovskiy Log present gold content up to 27 g/t, platinum – 0.75 g/t to mark the highly dislocated, and sulfidized silicified rocks penetrated by dykes gabbros. At 7 km to the north along stretch in the suite aboard river Sanarka in carbonaceous sediments intruded by dikes plagiogranites, set the gold content up to 7.7 g/t, platinum – 0.57 g/t, suggesting the presence here of a single zone of gold – platinum mineralization and recommend it for further exploration and evaluation project. Osipovsk manifestation of gold and platinum is the first object identified among carbonaceous deposits Zauralsk elevation.The research works indicate a very high perspective on the invention in gorodyshchensk and alexeyev suites gold – platinum, and in potapovsky suitet tungsten mineralization. Host rocks of Nizhnesanarsky granite massif, largely represented by carbonaceous deposits, riched by igneous rocks of different composition and age and survivored by moderate metamorphism, are the primary object for prospecting. The similar situation was noted by us on a number of manifestations of the southern Urals, in particular within Mayardaksky and Yamantausky anticlinoria and carbonaceous shales of Western framing Suunduksky granite massif
