摘要
中条山区铜矿床是在中条古裂谷地质构造环境中演化形成的。本文从涑水杂岩期－绛县期－中条期－西阳河期等不同时代地质历史演化，分别探讨了中条山区不同类型铜矿床时空分布和成因上的内在联系。它们早期形成的矿源层受不同时代的层位和岩性控制，但在后期的２０００～２１００Ｍａ和１８００～１９００Ｍａ较大规模的构造－热事件，对不同类型铜矿床进行了叠加和改造，使铜质进一步富集。
The copper deposits in the Zhongtiao mountains were formed in the geostructural environment of paleo rife On the basis of the evolution of geological history of Sushui complex stage Jiangxian stage Zhongtiao stage and Xiyanghe stage,the relationship between the spatial distribution and metallogenesis of different types of copper deposits in the Zhongtiao moutains is discussed The early formed ore source strata are controlled by the horizons and lithology of different ages The super imposition and transformation of different types of copper deposits by large scaled structure thermalevents of 2000-2100 Ma and 1800-1900 Ma had further inriched the copper grade and finally formed industrial deposits
