遥感在夹皮沟地区构造及金矿成矿规律研究中的应用

根据遥感图像解译,结合计算机图像处理及物、化探资料分析和野外验证,发现夹皮沟地区存在如下构造格局:北部为大面积古生代及中生代花岗岩出露区,南部存在一个太古宙变质岩穹窿(会全栈穹窿),而南部与北部地区之间为一北西向板庙子-兴安屯弧形韧性剪切带(与夹皮为地区金矿带分布一致).根据区内断层、褶皱的性质与分布以及糜棱岩片理产状和糜棱岩的分布特征分析,笔者认为板庙子-兴安屯北西向弧形韧性剪切带的形成及演化与会全栈穹窿有密切关系。据金矿的分布及储量资料,结合断裂的分布、断裂的交切关系等的分析,笔者认为北西向弧形韧性剪切带为该区金矿成矿的导矿构造,由其派生的北东、北北东向脆性构造为容矿构造。

THE APPLICATION OF REMOTE SENSING ON THE STUDY OF THE STRUCTURE AND THE MINEROGENTIC LAW OF GOLD IN JIAPIGOU REGION

According to the interpretation and the analysis of the remote sensing image, combined with computer processing. geophysical and geochemical information as well as field verification, the structural framework in this area is considered as follows: the granite body of palaeozoic and Mesozoic Era distributes extensively in the North of the area. There is a Archeozoic Eon metamorphic dome (Huiquanzhan dome) in the South. The tectonic belt lying between the North and the South of the area strikes in NWdirection. It is the curve ductile shear zone (gold mineralization belt) in Banmiaozi to Xingantuen area, and it is related very closely with Huiquanzhan dome in the formation and the evolution. It is considered as structure of passageways for ore fluids, and the structure derived from it is regarded as the structure for ore housing.
