摘　　要：铜矿床的形成与分布受到多种地质因素的控制,深部地质结构是其中之一。本文通过收集江西矿山工程施工区域地质、地球物理、地球化学等资料,结合野外地质调查和钻孔资料,对该区深部地质结构特征及其与铜矿床分布的关系进行了系统研究。研究表明,区域内发育多期次构造运动,形成了复杂的深部地质结构格局,包括深大断裂、隐伏岩基、岩浆岩侵入体等,它们控制了铜矿床的空间分布规律。基底隆起部位和深大断裂交汇处是铜矿床的有利部位,岩浆岩侵入体与铜矿化关系密切。基于对区域成矿构造背景的分析,提出了找矿勘查的有利区段和靶区,为下一步探矿部署提供了依据。本研究可为类似成矿区带的铜矿勘查提供借鉴。The formation and distribution of copper deposits are controlled by many geological factors,and the deep geological structure is one of them.By collecting geological,geophysical and geochemical data of mine construction area,combining with field geological survey and borehole data,this paper systematically studies the characteristics of deep geological structure and its relationship with the distribution of copper deposits in this area.The results show that multistage tectonic movements have formed a complex deep geological structure pattern,including deep faults,buried batholepths and magmatic intrusions,which control the spatial distribution of copper deposits.The intersection of basement uplift and deep fault is the favorable part of copper deposit,and magmatic intrusion is closely related to copper mineralization.Based on the analysis of regional metallogenic tectonic setting,the favorable sections and target areas of prospecting and exploration are proposed,which provide the basis for the next exploration and deployment.This study can provide reference for copper exploration in similar metallogenic zones.
