Primor'ye as a New Promising Region of Russia with Gold-Palladium-Platinum Ore Mineralization of a Nontraditional Type

摘要

The following regionally distributed contact-metamorphosed metalliferous sediments occur in association with each other in the lower part (Upper Ole-nekian-Ladinian) of the Triassic siliceous formation of the Sikhote-Alin, which is enriched in carbon: manganese-silicate (metamorphosed siliceous-rhodoch-rosite) rocks, "brown cherts" (cherts with pyrophanite and spessartine), tin-iron ores, "ilmenite-biotite-feld spar" (metamorphosed argillous) rocks, and "itabirites" (gold-bearing jaspers). These rocks occur in association with the products of hydrothermal regeneration composing bodies of different morphology and composition, including deposits of manganiferous skarnlike (amphibole-pyroxene) rocks and skarns.
