UNIQUE POLYCOMPONENT MINERALIZATION IN BRECCIA BODIES AT THE PAVLOVSK BROWN COAL DEPOSIT

Abstract

The Pavlovsk deposit is located at the margin of the Khankai Massif near the Voznesensk ore district, which is known for fluorite, tin, and tungsten deposits associated with the Paleozoic granitoid magmatism. The Cenozoic stage of ore formation in this region was related to rifting. Since the Eocene–Oligocene period, this region was characterized by the formation of numerous grabens followed by basic–alkaline basic volcanism and hydrothermal activity. Consequently, the Pavlovsk deposit area was marked by the formation of a unique Spetsugli germanium–coal deposit and several ore occurrences with unusual rare earth and gold–PGE mineralizations in coal-bearing sediments and argillized rocks of the basement. The present paper reports the first data on a new ore occurrence of the Cenozoic age. Ores of this occurrence are characterized by unique chemical and mineral compositions.
