SIKHOTE ALIN AS A POSSIBLE PROVINCE OF HYDROTHERMAL SEDIMENTARY GOLD, SILVER, PGE, TIN, ZINC, LEAD, AND TUNGSTEN DEPOSITS

Abstract

The Triassic–Jurassic carbonaceous sequence of Sikhote Alin contains metalliferous sediments composed of siliceous–rhodochrosite rocks and their metamorphosed analogues (mainly, manganese silicates and aluminosilicates), pyrophanite-bearing siliceous rocks (hereafter, brown cherts), tin–iron ores, ilmenite–biotite–feldspar rocks, and itabirites. Metalliferous sediments of all types have high contents of Au, Ag, and PGE.
