西藏达朵希巴地区成矿条件分析及遥感找矿预测

Analysis of metallogenic conditions and prospecting prediction by remote sensing technology in Daduoxiba area,Tibet

西藏革吉县达朵希巴地区处于班公湖—怒江成矿带西段物玛成矿亚带,成矿部位为岩浆岩与火山岩的接触带。利用WorldView-2高分辨率遥感数据在达朵希巴地区开展了构造及岩性解译,野外查证发现铜金矿化点。综合分析矿化点的矿化特征、成矿地质条件、控矿因素和找矿标志,建立了达朵希巴地区遥感找矿模式,为进一步的找矿工作提供了线索。

The Daduoxiba area, Tibet, is located in the Wuma sub-zone in the western part of Bangong Lake - Nu River metallogenic belt, the orebody occurs in the contact zone between magmatic rock and volcanic rock. Based on the interpretation of structures and lithology in Daduoxiba area by using WorldView-2 high resolution remote sensing data, several copper and gold mineralization oc- currences were found by the field investigation. The remote sensing prospecting model for Daduoxiba area was established by integrated analysis of mineralization characteristics, metallogenic geological conditions, ore- controlling factors and prospecting criteria, which provides key clues for further exploration in the area.
