摘要
The Nariniya lead-zinc deposit, recently discovered in the Tibetan Plateau, is genetically linked to the activities of potassic volcanic magma. The data suggest that the magma was sourced from enriched mantle or the as the nosphere mantle which had been contaminated by lower crustal material. Ore bodies occur as NWW-striking veins in volcanic rocks, consisting of galena, pyrite, quartz, calcite, dolomite, and minor sphalerite, chalcopyrite, and sericite. The alteration is dominated by muscovitization and pyritization. The Nariniya lead-zinc deposit is significantly different from carbonate-hostedlead-zinc deposits in Tuotuohe region in geological and geochemical characteristics, so they belong to different ore-forming systems.
