青海尕龙格玛矿区火山岩地层对成矿的控制作用

摘要

From the aspects of rock and mineralogical characteristics,rock chronology and rock geochemistry the volcanic strata are studied and analyzed in Galonggema copper polymetallic deposit.Combined with pre-vious research results of the tectonic setting of the northern part of Sanjiang mineralization belt,it is inferred that the deposit is formed in island arc environment,volcanic strata are closely related to copper polymetallic mineralization,and the control effect on mineralization is obvious.It has a certain Referential significance for the further geological prospecting in the region.%从岩石及矿物学特征、岩石年代学、岩石地球化学特征等几个方面对尕龙格玛铜多金属矿区火山岩地层进行分析研究,结合前人对三江北段成矿带大地构造背景研究成果,认为该矿床形成于岛弧环境,火山岩地层与铜多金属矿成矿关系密切,对成矿有明显控制作用,对本区进一步开展地质找矿有一定的借鉴意义.
