Abstract:
By studying the geological features of Lüliangshan copper deposit and Shuangkoushan lead-zinc deposit in the northern margin of Qaidam Basin Mountains,the author indicate that the adjacent rock of that two deposit is Ophiolite tectonic blocks that subjected to intense tectonic deformation fold and lower green-schist facies metamorphism,ore body which shows veined or like-layered occurs in the strong ductile shear zone band,respectively link to the two collision orogenesis,Caledonian and late Variscan to Indo-Chinese epoch,and probably corresponds with the formation of orogenic gold deposits of this area simultaneously.A series of Au dispersed flow element anomalies which has been found in the periphery district of Lüiangshan Copper and the Shuangkoushan lead-zinc are the cludes to looking for important target areas of potential orogenic-type gold deposits,and the indicating location of previously discovered VHMS copper mineralization in the Lüliangshan and SEDEX lead-zinc mineralization in the Shuangkoushan is important target area to look for post-transformation Qinglongtan-type copper mineralization and Xitieshan-type lead-zinc mineralization.
