摘要
The Narigongma porphyry molybdenum（-copper） deposit in Southern Qinghai Province is located in the northern part of Yulong metallogenic belt. The research on the deposit recognizes three types of alteration in the orefield, i.e. K-silicate alteration（biotite-K feldspar）, propylitic alteration（chlorite-epidote ± calcite） and feldspar-destructive alteration（sericite ± kaolin ± calcite ± anhydrite）. The metallogenesis is closely related to the quartz-molybdenite ± anhydrite ± chalcopyrite ± pyrite vein and molybdenite ± pyrite ± chalcopyrite vein.
