摘　　要：平和矾山地区围岩蚀变类型为次生石英岩化,可细分为石英-黄铁矿-明矾石化、硅化和绢云母-叶蜡石化等三个相带,具北西向带状对称式水平分带和略显垂直分带现象。蚀变以高硫型明矾石次生石英岩化为主,相当于紫金山铜金矿床蚀变分带的外带,即石英-明矾石化带。深部可能贮存有隐伏的铜多金属矿体,有进一步找矿的前景。The country rock alteration type is the secondary quartz lithification in the Fanshan of Pingshe County,and may subdivide for the quartz-pyrite-alunitization,the silicification and the sericite-pyrophylitization,which is possessed of the north-west banding symmetric horizontal zoning and the little vertical zoning characteristics.The alteration type is mainly the secondary quartz lithification of the alunite of the high sulphur type,which is equal to the outer of the alteration zoning of the Zijinshan copper-gold deposit,that is to say the quartz-alunite lithification belt.There is presumably conceraled copper polymetallic ores in the deep part.There is further ore-finding perspective targets.
