青海黑石山地区铜多金属矿床地球物理特征及找矿标志

青海省都兰县黑石山地区铜多金属矿区内断裂构造发育,岩浆活动强烈,对区域的电物性特征、磁物性特征进行了分析,测定了区内出露的各类地层、岩(矿)石物性标本,并对物性标本测定的参数进行了统计计算,分析结果客观真实地反映了区内各地层、各类岩(矿)石之间的物性差异及其特征,然后对研究区圈出5条异常带进行了磁异常特征分析及解释,对3个测区进行了地球物理充电异常特征分析与解释,并分析了地质、地球物理和地球化学等找矿标志,为矿区下一步实施勘查工作的部署提供了技术支持及理论依据。

Geophysical Characteristics and Prospecting Indicators of the Copper-polymetallic Deposits in the Heishishan Area,Qinghai

There are numbers of fault structures exsiting in the copper-polymetallic mining area of Heishishan in Dulan County, Qinghai, in where the magmatic activity was very intensive. This paper has analyzed the regional electrical and magnetic properties of the area, indentified the various types of strata exposed in the area, tested the rock (ore) samples and calculated the statistical parameters of the samples according to the tests. The foresaid analytical results objectively and truly reflect the physical differences and characteristics of various of layers and rocks (ore). Accordingly, analysis and interpretation have been done on magnetic anomaly characteristics of 5 anomalous zones delineated in the study area, also on the geophysical charging anomaly characteristics of 3 surveyed areas. In addition, this paper analyzed the prospecting indicators such as geology, geophysics and geochemistry in order to provide technical support and theoretical basis for future prospecting in the mining area.
