摘　　要：破头青断裂为玲珑金矿田一级控矿构造带,是重要的导矿、容矿构造;其构造蚀变分带从下盘到上盘为:钾长石化带、绢云母化带和硅化黄铁矿化带。绢英岩及其附近的钾化花岗岩、正常花岗岩的矿化元素、稀土元素分析结果表明,破头青断裂带REE配分模式表现为LREE富集型,轻、重稀土分异明显,La/Lu=8.37-65.03,具有Eu异常,δEu=0.67～1.46,Ce无明显异常;Au与Ag、As、Cu、Mo等矿化元素具有相对较高的相关性,是同一成矿作用的结果。Potouqing fault was the first-grade fracture controlling orebodies,its alterative zones from the hanging wall-rock to the ore-body include potash zone,sericitization zone,silicification zone,pyritation zone etc.The results of REE and elements related to mineralization in Potouqing fault show that REE patterns appear as LREE-rich type,with better fractionation of lighter and heavy REEs and La/Lu=8.37-65.03.Ore-forming fluids have Eu abnormity,withδEu=0.67-1.46 and without Ce abnormity.Au is strongly correlated to Ag,As,Cu,Mo which is the result of the same metallogeny.
