摘要
构造蚀变岩型金矿产于拆离断层附近陡倾斜破碎带中 ,矿体定位明显受控于拆离断层。文中分析了不同成矿阶段、围岩蚀变和含金破碎带产状变化对矿化富集的影响。根据矿化和主要蚀变类型的对称分布特点 ,认为拆离断层是金矿的直接导矿构造。
The structural altered rock type gold deposit is hosted in steep dipping fracturing zones near the detachment fault. It is clear that the location of orebodies is controlled by the detachment fault. The effects of varying metallogenic stages, wall-rock alterations and changes of attitude of the glod-bearing fracturing zones on mineralization and enrichment are analysed in the paper.According to the feature on symmetric distribution of the mineralization and main alteration types,the author has considered that the detachment fault is the direct ore-passing structure of the gold deposit.
