| 中文摘要: |
| 温区矿区位于西藏冈底斯斑岩铜矿带东部南缘，成矿条件优越，已发现多处大中型铜(钨)多金属矿床，本矿区现阶段矿床类型主要为矽卡岩型钨(铜)矿。此次工作是在 1∶5万水系沉积物温区 Cu-Mo-W异常区内开展 1∶2 5万岩屑地化测量，共圈定 61个异常，大体构成 3个异常带，分别是 Hy-1 Au-Ag-As-Bi-Mo、 Hy-2 Au-Ag-As-Pb、 Hy-3 Cu-Mo-W。通过异常验证，在 Hy-3 Cu-Mo-W综合异常带见矿效果较好，值得下一步继续研究；其他两个综合异常前缘晕较发育面积大，也显示深部具有较大的找矿空间。本文同时讨论了该矿区成矿有利的条件，提出了在该区带寻找矽卡岩型铜钨多金属矿水系沉积物、土壤或岩屑地球化学元素组合有其独特性，对下一步地质找矿有较好的指导意义。 |
| 英文摘要: |
| Wenqu evaluation area is located in the southern margin on east side of Gangdise porphyry copper belt,Tibet,with favorable metallogenic conditions Many large and medium-sized copper (tungsten) polymetallic deposits have been found in this area At present, the deposit type in this mining area is mainly skarn type tungsten (copper) deposit The 1∶25000 lithic geochemical surveys were carried out in the Cu-Mo-W anomaly areas of 1∶50000 stream sediment area in Wenqu,61 anomalies were delineated and these anomalies could be generally divided into three anomalies,such as HY-1 Au-Ag-As-Bi-Mo,HY-2 Au-Ag-As-Pb and HY-3 Cu-Mo-W Through anomalies veri cation,good mineralization has been found in HY-3 Cu-Mo-W comprehensive anomaly zone, which is worthy further study Other two comprehensive anomalies have large front halo areas showing great prospecting potential in the deep part At the same time,this paper discussed the favorable conditions of mineralization in the study area,and it also pointed out that the geochemical elements group in stream sediment,soil or cuttings has its own uniqueness for searching skarn type Cu-W polymetallic deposits,which has a good guiding signi cance for the further geological prospecting |
