马鬃山铜矿的成矿条件和成因探讨

Discussion on metallogenic conditions and causes of MazongShan Copper Mine

铜矿床在金属矿产资源开发利用过程中占有举足轻重的地位,本文在前人研究的基础上,通过分析马鬃山铜矿的成矿地质背景、构造背景、变质作用、重磁背景及成矿特点等,对马鬃山铜矿的成因进行了探讨,为周边找矿指出了方向。研究结果表明,马鬃山铜矿矿体主要受北西向裂隙控制,局部显示同时受北东向裂隙影响,其矿床成因热液脉状是其表象,真正的成因类型应是斑岩型或超基性岩型,其深部找矿潜力巨大。

Copper deposit has play a decisive role in the development and utilization of the status of metal mineral resources in the process,based on the previous research,by analyzing the MazongShan copper mineralization geological background,tectonic background,metamorphism,gravity and magnetic background and metallogenic characteristics,discussed the causes of formation of Mazongshan Mountain Copper Mine,point to the direction for prospecting around.The results show that,MazongShan orebody is mainly controlled by the NW trending fracture control,display and local North East fracture effect,its causes thermal deposit liquid vein is its representation,genetic type really should be porphyry or ultrabasic rock type,the deep prospecting potential.
