河南省西峡县上庵-天宝寨金铜矿床地质特征及矿床成因探讨

Geological Characteristics and the Genesis Discussed of Au-Cu Deposit in Shangan-Tianbaozhai,Xixia County,Henan Province

上庵-天宝寨金铜矿床位于秦岭造山带北缘东段,为一产于蚀变构造破碎带中蚀变岩型金铜矿床。成矿受构造、岩浆岩控制明显,绢云母化、硅化、黄铁矿化等围岩蚀变强烈,矿床成因属热液型。区内圈出的数个金-铜-铅-锌组合异常以及通过工程揭露控制发现和圈定的12个金铜矿(化)体等勘查成果联合显示,区内具有较大的勘查潜力。

Shangan-Tian Baozhai Au-Cu deposit is located in the east section of northern part of Qinling orogenic belt and it belongs to altered rock type Au-Cu deposit occurred in tectonicalteration belt.Mineralization is obviously controlled by structure and magmatic rock.Wall rock alteration is intense,such as Sericitization,silicification,pyritization and so on.So the ore genesis can be attributed to hydrothermal type.The result of geological survey shows good prospecting in the area,according to several Au-Cu-Pb-Zn anomalies in the area and twelve Au-Cu mineralization by engineering.
