METALLIFEROUS SEDIMENTS OF THE TRIASSIC CHERTY FORMATION IN THE OL'GA ORE DISTRICT OF PRIMORYE: TIN-NOBLE METAL ORES OF A NEW GENETIC TYPE

Abstract

The Triassic cherty formation of Sikhote Alin hosts metalliferous deposits. They are commonly represented by siliceous–rhodochrosite rocks and their metamorphosed analogues (primarily, consisting of Mn-silicates and aluminosilicates) with high concentrations of Ga, Au, Pt, Pd, and other metals [3]. In the Ol’ga district, the metalliferous deposits are also represented by chocolate-brown siliceous rocks (hereafter, brown cherts) and tin–iron ores.
