摘　　要：大厂锑矿位于黔西南凹陷,是我国重要的锑矿产地之一。矿区内围岩蚀变现象非常发育,由于成矿流体和围岩的水岩反应经常使流体和周围矿物进行物质交换,蚀变作用发生过的矿体可以在一定程度上说明成矿流体的物质成分。围岩蚀变在一定程度决定了矿体的分布,本文着重对其作用特征进行探讨。Dachang antimony deposit is located in southwestern Guizhou sag, is one of China＇s major antimony deposit. The alteration of the surrounding rock in the mining area is very developed. Because the water-rock reaction of the ore-forming fluid and the surrounding rock often exchanges the material and the surrounding minerals, the ore body which has occurred in the alteration can explain the ore-forming fluid to a certain extent ingredient. The alteration of the surrounding rock determines the distribution of the ore body to a certain extent. This paper focuses on its characteristics.
