遥感信息在青海督冷沟地区成矿预测中的应用

APPLICATION OF REMOTE SENSING INFORMATION IN THE MINERALIZATION PREDICTION IN THE DULENGGOU AREA, QINGHAI PROVINCE

青海督冷沟地区处于东昆仑成矿带,具有较大的找矿潜力。在该区运用TM遥感数据,进行了1∶5万遥感找矿信息提取,结合地质和化探异常资料分析,预测了5处找矿远景区,通过野外查证,在塔妥煤矿南部找矿远景区中发现大小铜矿体15条,铅矿体1条。由此可见,遥感信息在矿产资源潜力评价及找矿预测中具有重要作用。

Dulenggou area of Qinghai province is located in the east of Kunlun metallogenic belt, and has a very large ore-finding potential. In the area, TM data is used to extract Remote Sensing ore-finding information with a scale of 15000. Combined with analyzing of geological and geochemical abnormality, five ore-finding prospects are predicted. By the field survey and verification in the ore-finding prospect in south of Tatuo coal mine, fifteen large or small copper orebodies and a lead orebody were found. It is concluded that Remote Sensing information can play an important role in the evaluation of mineral resources potential and ore-finding prediction.
