摘　　要：鄂东南地区构造蚀变岩型金矿可分为浅变质碎屑岩构造蚀变岩,碳酸盐岩构造蚀变型等亚类型,北东向断裂是金矿一级矿断裂构造,次级断裂控制矿床分布,主要有变化硅化,黄铁矿化、绢云母化等。区域地质构造背景基础上,结合点上工作,总结鄂东南浅变质碎屑岩构造蚀变岩金矿成矿特征,探讨金矿找矿方向。Tectonic altered rock type gold deposits in southeast Hubei can be divided into shallow metamorphic clastic tectonic altered rocks,carbonate tectonic altered rocks and other subtypes.On the basis of regional geological structure background,the characteristics of gold mineralization are summarized,and the prospecting direction of gold ore is discussed.
