| 摘 要： | 赋矿的普朗含矿复式斑岩体,具典型斑状特征及铜、钼、铁成矿专属性,由边缘到中心具石英闪长玢岩→石英二长斑岩演化关系,硅化钾化、绢英岩化蚀变与铜矿关系密切,尤以石英二长斑岩蚀变和矿化作用最强烈。硫同位素表明岩体属幔-壳源硫特征,铅同位素显示岩体铅集中分布于造山带演化线附近及下地壳、造山带、岛弧重叠区的特征。

| Abstract: | The Pulang ore-bearing complex porphyry body is characterized by the typical porphyritic characteristics and Cu-Mo-Fe metallogenetic specialization.The evolution relationship is quartz diorite porphyrite—adamellite porphyry from margin to center.The Cu deposit is close related with the alteration of silicification,K alteration(potash-feldspathization and biotitization),sericitolitization.The alteration and metallogenesis of adamellite porphyry are especially intense.The S isotope shows the mantle-crust derived characteristics of rock body.The Pb isotope shows the characteristics of Pb concentration near evolution line of orogene and in superimposition area of lower crust,orogene and island arc. |
