大厂铜坑区东岩墙东部找矿潜力

Prospecting Potential of East Area of Dongyan Wall in Dachang Copper Pit District

通过对大厂铜坑矿区东岩墙开展构造研究及找矿预测,认为花岗斑岩为成矿后断裂充填物,预测东部仍存在矿体,经过坑钻工程验证,探获了锡多金属矿体(332+333)矿石资源量112万t,同时发现深部还存在锌矿体。实践证明,东岩墙东部找矿潜力较大,值得进一步研究。

Through the structural study and prospecting prediction of Dongyan Wall of Dachang Copper pit ore, the paper regards granite porphyry as the breakage filling of after mineralization. It predicts that ore body exists in the east area. By pit drilling work, it explores that the mineral reserve of tin multi--mineral ore （332＋333） is 1.12 million ton. Meanwhile, it finds that there is zinc ore in deep. Practice has proved that there is larger prospecting potential at the east area of Dongyan Wall, worthy of further study.
