摘　　要：南澜沧江火山弧成矿带成矿条件优越,一直备受地质学家重视。通过对瘴气塘矿段1272及1220中段进行详细的构造蚀变岩相研究,划分了构造蚀变岩相分带,即围岩蚀变由中心向外依次为硅化钾化带→绢云母化带→青磐岩化带。矿化与区内蚀变有着密切联系,因此蚀变分带特征的研究为进一步找矿提供重要的依据。The South Lancangjiang volcanic arc metallogenic belt has been well regarded by geologists as its favorable metallogenic conditions.The tectonic alteration lithofacies have been divided by the study of the 1272 and 1220 segment of miasmian section,which means that the wall rock alteration is from the center to the silicified potassium zone,sericite zone and green rock zone.Mineralization is closely related to regional alteration.Therefore,the study of alteration zonation features provides important basis for further prospecting.
