摘　　要：雪鸡坪斑岩铜矿床位于"西南三江"铜多金属成矿带,中甸-义敦岛弧带南部,矿区赋矿岩体为印支期石英闪长玢岩及石英二长斑岩。矿区围岩蚀变强烈,分带明显,且矿化强度与蚀变有着重要的联系。因此,研究其围岩蚀变与矿化特征对该矿区下一步找矿有着重要的作用。The Xuejiping porphyry copper deposit lies in the ＂Sanjiang＂ polymetallic metallogenic zone, and Zhongdian - Yidun island arc of the lndosinian Orogeny. The main rocks of this mining are diorite quartz porphyrite and quartz monzopor- phyry. There are fierce country -rock alteration in this mining, and zoned clearly. It has important contact with the intensity of mineralization and alteration. Consequently, studying the Fea- tures of country - rock alteration alteration and mineralization has the most important effect for the next prospecting.
