| 摘 要： | 中条山重要铜矿床都产于早元古代活动带中。它们是:绛县群(2500—2300 Ma)下部变质泥质—半泥质岩中的沉积变质铜矿床和中上部变质钾质火山岩建造中的变质火山斑岩铜矿床;中条群(2300—1830 Ma)变质碳酸盐黑色页岩建造中的沉积变质-再造铜矿床。这些原生成因不同的矿床,经过180 Ma左右的中条运动及其变质作用,而表现了某些相似的热液和地球化学特征,但没有从根本上改变受原岩建造控制的特点。

| Abstract: | The major copper deposits in the Zhongtiao Mountains all occur in the Early Proterozoic mobile belt. They can be classified into three types:1. Meta-sedimentary copper deposit in meta-pelitic-semi-pelitic rock formation of the lower Jiangxian Group (2500-2300 Ma).2. Meta-volcanic porphyry copper deposit in meta-potassic volcanic rock formation of the middle and Upper Jiangxian Group.3. Meta-sedimentary-remoulded copper deposit in meta-carbonate black shale formation of the Zhongtiao Group (2300-1830 Ma).Having undergone the Zhongtiao Movement at about 1,800 Ma and its related regional me-tamorphism, these deposits of different primary genesis exhibit similar hydrothermal and geo-chemical features, but are still controlled by the primary sedimentary or volcanic sedimentary formations. |
