The Kuergasheng lead-zinc deposit, which is located in the middle of the Sailimu massif within western Tianshan of Xinjiang, is hosted in NW-trending faults and has veinlike and lenticular ore bodies. The primary fluid inclusions trapped in quartz include pure liquid inclusions and gas-liquid two-phase inclusions. Thermometry of two-phase inclusions gives a range of homogenization temperatures between 135.4 ℃ and 158.8 ℃. It is inferred that these data may suggest that a considerable part of the ore-forming metals might have come from the surrounding rocks. In summary, the Kuergasheng lead-zinc deposit may be a distal epithermal ore deposit related to porphyry.
