山西省垣曲县葫芦峪一带铜矿地质特征与矿床成因

Geological characteristics and genesis of copper deposits in huluyu area,Yuanqu County,Shanxi Province

山西省垣曲县葫芦峪一带铜矿大地构造位置位于华北板块华北南缘板内活动带中条山-焦作板隆中条山块凸,笔者通过野外勘查,对区内地层、构造、岩浆岩、物化探特征等方面进行了综合研究,发现该矿体赋存于绛道沟组大理岩、钙绢片岩建造中,严格受地层控制,沉积条件是成矿的主导因素,并且该矿床具有大量变质成因标志,综合研究,矿床属于沉积变质岩型。

The tectonic position of huluyu copper deposit in Yuanqu County of Shanxi Province is located in Zhongtiaoshan Jiaozuo plate uplift Zhongtiaoshan block convex in the intraplate active zone of the southern margin of North China plate.Through field exploration,the author conducted a comprehensive study on the strata,structure,magmatic rocks,geophysical and geochemical characteristics in the area,and found that the ore body occurred in the marble and calcium sericite schist formation of jiangdaogou formation and was strictly controlled by the geological conditions The deposit is controlled by strata,sedimentary conditions are the main factors of mineralization,and the deposit has a large number of metamorphic genetic indicators.Comprehensive study shows that the deposit belongs to sedimentary metamorphic rock type.
