五台—恒山地区多金属矿远景区预测及找矿方向

利用移动平均法对五台—恒山地区7幅1∶20万水系沉积物数据进行重新处理,并结合本区1∶20万重力数据和1∶5万航磁数据,发现所获得的综合异常与燕山期岩体相关矿床具有很好的吻合性。研究选取Au、Ag、Cu、Pb、Zn等综合异常以及高磁、低重异常作为预测准则,在本区共预测出13处与岩体成矿作用有关的多金属矿远景区。已有资料显示,本区共存在9条NW向断裂构造带,岩体侵位受NW向断裂和NE向断裂交叉部位控制,已知出露岩体与本次预测的11处远景区绝大部分分布在断裂构造带上,构成多条构造岩浆岩带,多金属矿床与燕山期岩体有着密不可分的联系。

The prediction and prospecting direction of polymetallic deposits in the Wutaishan-Hengshan area

In this study, the moving average method was used to reprocess the 1∶200,000 stream sediments data from seven sheets in Wutaishan-Hengshan area. In combination with the 1∶200,000 gravity data and 1∶50,000 aeromagnetic data obtained in this area, the authors found that the comprehensive anomalies are in good agreement with the deposits related to the Yanshanian rock mass. Choosing elements such as Au, Ag, Cu, Pb, Zn anomalies and high-magnetic and low-gravity anomalies as the prediction criteria, the authors predicted a total of 13 polymetallic ore prospective areas related to the mineralization of rock masses in the study area. According to available data, there are 9 NW-trending fault structural zones in this area. The intrusive position of the rock mass is controlled by the intersection of the NW-trending fault and the NE-trending fault. Most of the known rock masses and the 11 prospective areas predicted by this paper are distributed in the fault structural belt, forming multiple tectonic magmatic zones. The polymetallic ore deposit is inextricably linked with Yanshanian rock mass.
