摘　　要：甲岗雪山钨钼(铋)多金属矿床位于昂孜错-崩纳藏布-甲岗雪山-色日荣成矿带西段,是首次在西藏发现并开展普查评价的中型规模的石英大脉型钨钼(铋)矿床。辉钼矿Re-Os同位素模式年龄平均值为21.37Ma,成矿时代为喜马拉雅中期,钨钼(铋)等金属矿化与喜马拉雅中期的二长花岗岩体有关。此外本文对区域成矿地质条件、矿体特征、控矿因素、矿石质量、围岩蚀变等作了系统论述。The Jiagang Snow Mountain tungsten-molybdenum(bismuth)polymetallic deposit is located in the western section of the Angzi Co-Bengna Zangbo-Jiagang Snow Mountain-Serirong metallogenic belt.It is the first medium-sized quartz vein-type tungsten-molybdenum(bismuth)deposit discovered and surveyed in Tibet.The average Re-Os isotope model age of molybdenite is 21.37Ma,and the mineralization age is the middle Himalayan.The mineralization of tungsten,molybdenum,bismuth and other metals is related to the monzogranite body in the middle Himalayan.In addition,this paper systematically discusses the regional metallogenic geological conditions,ore body characteristics,ore-controlling factors,ore quality,wall rock alteration,etc.
