摘 要:在研究柴北缘绿梁山铜矿、双口山铅锌矿矿床地质特征基础上,指出上述矿床围岩为遭受了强烈褶皱构造变形及低绿片岩相变质的蛇绿混杂岩构造块体,矿体呈脉状或似层状产出于韧性剪切带内的强带内,分别与加里东期和晚华力西期—印支期的两次碰撞造山作用相联系,并很可能与区域上对应时期的造山带型金矿床的形成同步。暗示绿梁山铜矿区和双口山铅锌矿区外围是寻找潜在的造山带型金矿床的重要靶区,而在绿梁山铜矿区新发现的VHMS型铜矿化和双口山SEDEX型铅锌矿化指示位置,是寻找遭受后期改造的青龙滩式铜矿化和锡铁山式铅锌矿化的重要靶区。By studying the geological features of Ltiliangshan 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 duc- tile shear zone band, respectively link to the two collision orogenesis, Caledonian and late Variscan to In- do-Chinese epoch, and probably corresponds with the formation of orogenie gold deposits of this area sim- ultaneously. A series of Au dispersed flow element anomalies which has been found in the periphery dis- trict of Liiiangshan 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 Lfiliangshan and SEDEX lead-zinc mineralization in the Shuangkoushan is im- portant target area to look for post-transformation Qinglongtan-type copper mineralization and Xitieshan- type lead-zinc mineralization.
