摘　　要：丁家山金矿位于青木川-关口垭逆冲型韧性剪切带和金(铜)成矿带。本文研究了丁家山金矿的围岩蚀变类型及特征、蚀变期次,探讨了围岩蚀变与成矿之间的关系,将丁家山金矿分为成矿期和表生期,成矿期从早到晚可分为4个成矿阶段:硅化石英阶段、石英-黄铁矿阶段、金-多金属硫化物阶段、硅酸盐-碳酸盐阶段。Dingjiashan gold deposit is located in the north wing of Yuquanba synclinal slope,in Qingmu Chuan-Guankou ya thrust ductile shear zone and gold (copper) metallogenic belt. In this paper,the characteristics and stages of surrounding rock alteration of Dingjiashan gold deposit are analyzed and studied,and the relationship between it and gold mineralization is discussed,which is helpful to the further production and prospecting of gold deposits in the mining area,and also has great guiding significance for the prospecting of gold deposits in the region.
