津巴布韦GOOD HEART金矿成矿地质特征浅析

Analysis on Metallogenic Geological Characteristics of GOOD HEART Gold Deposit Zimbabwe

津巴布韦GOOD HEART金矿为绿岩带石英脉型金矿;矿体的受北东向复式背斜褶皱控制,分布在褶皱带核部及附近翼部裂隙带内。GOOD HEART金矿由于元古代花岗岩浆侵入提供热动力源;使矿源层内金离子活化沿北东向挤压剪切构造带迁移并在构造有利部位富集成矿。

GOOD HEART gold deposit in Zimbabwe is a quartz vein type gold deposit in greenstone belt.The orebody is controlled by the NE-trending compound anticline fold and distributed in the core of the fold belt and the fracture zone near the wing.GOOD HEART gold deposit provides thermal power source because of Proterozoic granitic magma intrusion,which makes gold ion activation migrate along NE compression shear structural zone and enrich metallogenesis in the favorable part of the structure.
