Abstract

In the graphitized rocks of the northern margin of the Khankai terrane (Primorsky Krai), new manifestations of noble and rare-earth metals have been revealed with the participation of the authors. Ore mineralization is characterized by the presence of high-grade gold and silver, as well as monazite, xenotime, sulphides (pyrite, pyrrhotite, pentlandite, chalcopyrite, sphalerite, Co-containing arsenopyrite, galena, bismuthin, tetradymite), barite, rutile, uraninite. Graphite ore formations in the value of δ13C (from-2.1 to -5.5% 0) corresponds to mantle carbon. It seems that the main suppliers of carbon in the formation of noble metals, rare-earth-graphite ores were deep fluid flows.

KeywordsKhankai terrain, high-carbon rocks, graphite, noble and rare-earth metals, isotopic composition of carbon
