内蒙古白梁东铜金矿地质特征及找矿前景

Geological characteristics and prospecting potential of Bailiangdong copper gold deposit in Ejina,Inner Mongolia

通过野外地质勘查、显微岩矿鉴定等成果,对白梁东石英脉型铜金矿地质特征及其成因机制进行了初步的分析研究。综合分析表明,多金属矿体多呈香肠状、透镜体产出,受不同级次的北西向、北北西向构造断裂控制,产于华力西晚期二长花岗岩体外接触带之下石炭统白山组、绿条山组地层,严格受岩体和地层控制。矿体为华力西中晚期构造—岩浆活动的产物。

The Geological Characters and the Origin of Bailiangdong Copper Gold Deposit were preliminary studied by means of regional geological survey and rock-mineral identification. The analytic results show that:the polymetallic ore body is sausage shape or lensoid structure, strictly controlled by the NW-trending、the NNW trending structural faults in different orders. They occur in the Baishan and Lutiaoshan Formation of Lower Carboniferous and as exo-contact zone of Late Variscan granite adamellite, which was resulted from tectono-magmatic activities during the Middle-Late Variscan period.
