摘  要:寨上金矿位于西秦岭岷县—礼县成矿带西部。为缩小找矿靶区,发现有利成矿带,寻找有价值的工业矿体,对区内1∶20万水系沉积物所圈定的金异常区进行了1∶5万水系沉积物测量,在此基础上又开展了1∶1万土壤测量,共发现8处金异常,圈出2条金矿带。利用复合极距激电联合剖面测量对土壤金异常进行了评价,钻探工程验证金异常深部存在有价值的工业矿体。The Zhaishang gold deposit is located in the west of Min County to Li County mineralization belt of west Qinling. To narrow down the target area, find out the favorable mineralization belt, and seek valuable industrial ore bodies, 1∶50 000 stream sediment survey was carried out in the gold anomaly area, which was blocked out by the 1∶200 000 stream sediment survey. Based on this, 1∶10 000 soil survey was followed. According all above,8 gold anomalies were discovered and 2 gold belts were locked out. The gold anomaly analysis was made by different polar distance,the drilling process verified that these exist valuable industrial ore bodies in the depth of gold anomalies.
