摘　　要：对西藏昆仑山南坡1∶2 0万化探工作中圈出的土则雪山HS1 6综合异常查证中,发现宽850m ,长约4km ,由8个铜、铜锌、铜铅锌和2个铜矿化体组成的大型铜多金属矿带,其矿床成因类型为兼具沉积砂岩型铜矿和中低温热液型多金属矿床的沉积改造型矿床。该调查区铜的找矿潜力极大,具备有发现矿田级铜矿产的前提。作为铜矿的伴生,共生银、铅、锌矿也具有相当的找矿潜力。Investigation and verification of HS16 composite anomalies delineated in Tuzexueshan during geochemistry exploration at 1:200,000 in the south slope of Kunlun mountain in Tibet has discovered a large-scale copper-polymetallic mineralized zone, which is composed of 8 mineralized bodies containing copper, copper-zinc, copper-lead-zinc and 2 copper mineralized bodies with a length 4km and a width 850m. The genesis of mineralization can be recognized as sedimentary deformation types with sedimentary sandstone copper type and moderate-low epithermal polymetallic deposit. Copper prospecting in this area will have a great potential and is possible to find out a copper field. Otherwise, some associated minerals, such as silver, lead and zinc, would have a great potential also in this area.
