摘要
Zhaxikang deposit is the only large Pb-Zn-Sb-Ag symbiotic deposit in the northern Himalayas gold-antimony polymetallic belt,with its ore body located in the high-angle twisting fault zone striking SN direction. The δ34S of pyrite, sphalerite, galena, jamesonite, stibnite ranges from 4.5‰ to 12.0‰, with the majority ranging from 8‰ to 11‰, and it is enriched in sulfur with a narrow range, indicating that the same sulfur source, mainly from the rock formation in the marine sulfur reduction. The deposit formed by replacement and filling along the SN fault zone, which belongs to sedimentary-structural-geothermal water multi-stage replacement and hydrothermal vein deposits.
