APPLICATION OF GEOPHYSICAL TECHNOLOGY IN THE DEEP PROSPECTING IN JINCHANGGOU COPPER AND MOLYBDENUM DEPOSIT, HEILONGJIANG PROVINCE

摘要: 根据矿区内铜钼矿体与磁铁矿共生关系，采用高精度磁法测量，间接寻找铜钼矿体赋存有利部位；结合矿区岩（矿）石磁场特征圈定岩性界限，划分构造分布特征；采用可控源音频大地电磁法（CSAMT），根据区内不同深度岩层的电性特征，圈定岩体与老地层的接触带位置；并根据岩（矿）石电性差异，寻找矿致低阻异常，为深部找矿提供依据.

Abstract: Based on the coexistence relationship of the Cu-Mo ore and magnetite in the orefield, the Cu-Mo ore bodies can be indirectly located by high-precision magnetic survey. The lithological boundaries and tectonic distribution are ascertained with analysis on the magnetic characteristics of rocks in the orefield. With the controlled-source audiomagnetotellurics(CSAMT), the contact zones of intrusive rocks and strata are delineated by the electric characteristics of rocks in different depth. The electrical differences of rocks can be used to look for ore-induced low resistivity and provide basis for deep ore prospecting.
