吉林省夹皮沟金矿区南段遥感构造解译及找矿方向探讨

Remote sensing structure interpretation and prospecting direction in the south part of Jiapigou gold mining area,Jilin Province

本文通过对夹皮沟金矿区南段遥感地质构造解译,提出该区段金矿产出受中生代形成的"帚状"压扭性断裂构造和"扇形"张性断裂构造体系的联合控制。"扇形"断裂构造体系发育在兴安屯—云峰村环形构造的东半部,主要为中生代花岗质岩浆侵入作用形成,为金等成矿元素的有利赋存空间。根据构造岩浆活动与金矿成矿作用的关系,探讨了区内金矿的成因。该研究结论为夹皮沟金矿区南段开展地表及深部找矿具有重要意义。

Through interpretation of the remote sensing geological structure in the south part of Jiapigou gold mining area,pointed out that the gold deposit occurrence in the district where was joint controlled by the ＂broom＂ type compresso-shear rift structure and ＂fan＂ type tensional fault structure system in the Mesozoic era.The ＂fan＂ type tensional fault structure system developed in the east half part of Xing＇antun-Yunfengcun annular structure and the structures formed by the Mesozoic era granite magma intrusion,and supplied with available occurrence space for gold and other mineralizing elements.According to the relationship between the structure magmatic activities and gold mineralization,this paper discussed the genesis of gold ore in the study area.The research conclusion has important significance for the surface and deep prospecting in the south part of Jiapigou gold mining area.
