摘　　要：熊耳山地区金矿的成矿物质来源主要来自基底太华群中深成变质岩、燕山期钙碱性岩浆岩以及构造蚀变岩。矿床受燕山期岩浆岩和构造控制明显,不同级别的构造控制着金矿的规模和展布。控矿断裂具有明显的方向性,断裂交汇处及断面产状变化处控制矿体或富矿体产出。文章从花岗岩特征和构造的控矿作用方面总结该区金矿的成矿规律,以期为进一步找矿提供借鉴。The ore-forming matter sources for the Xiong ershan gold deposit is mainly come from the metamorhpic rocks of Taihua Group,calc-alkaline magmatic rocks and tectonic altered rocks of Yanshanian.The deposit is significantly controlled by Yanshanian magmatic rocks and structures with different classes of structures controlling the scale and spread of the gold deposit.With distinct directivity,the ore-controlling faults have orebodies and enriched orebodies controlled and occurred at their intersection sites an...
