中条山地区地质特征及铜矿床类型

中条山地区出露的地层主要有新太古界涑水麻粒岩-角闪岩相杂岩、绛县群角闪-绿片岩岩相变质岩、古元古界中条群绿片岩相变质岩、担山石群变质砾岩-石英岩、西阳河群安山岩、沉积岩和中新元古界沉积岩。区内岩浆作用强烈，以绛县期、西阳河期火山喷发、涑水期岩浆侵入为主，火山作用为铜矿床的形成提供了大量的成矿物质。深断裂构造和褶皱构造，特别是其交汇处为成矿物质的运移和沉淀提供了空间。按成因该区铜矿床可分为次火山-火山气液再造型、远火山-沉积变质型、沉积变质型、层控热液型和热液脉型铜矿床，代表性矿床有铜矿峪、筐子沟、胡家峪、横岭关、落家河等矿庆。

Geological Features and Copper Deposit Types in Zhongtiao Mountains

In Zhongtiao Mountains , the main strata are Archean Shushui Complex(granulite facies complex), Jiangxian Group (amphibo-greenschist facies metamorphic rock), Paleoproterozoic Zhongtiao Group (metamorphic conglomerate and quartzite), middle Proterozoic Xiyanghe Group(andesite and sedimentary rock), Neoproterozoic Changcheng group(sedimentary rock). The magmatism were strong, dominated by Jiangxian and Xiyanghe epoch volcanic eruption, Shushui epoch magmatic intrusion, the volcanism supplied large amount of metallogenic material for Cu deposit formation. Deep faults especially their crossings, provided space for the movement and deposition of ore-forming material. According to genesis, the Cu deposits can be divided as subvolcanic-volcanic hydatogenetic reconstructed type, far volcanic-metamorphic sedimentary type, metamorphic sedimentary type, volcanic-sedimentary reconstructed type, hydrothermal type and hydrothermal vein type. The representative deposits are Tongkuangyu, Bizigou, Hujiayu, Henglingguan and Luojiahe. The most important deposit in the region is Tongkuangyu Cu deposit of volcanic-subvolcanic hydatogenetic reconstructed type.
