摘　　要：江西永平铜矿与朱溪铜钨矿位于华南地块,本文对两个矿区的大地构造背景、地层岩性特征、矿体赋存特征、矿石组构及围岩蚀变特征进行了系统的对比研究。研究表明,两个矿区均受深大断裂系统控制,具有相似的矿体赋存特征和矿石组构特征,但在围岩蚀变类型和矿化分带方面存在明显差异。朱溪铜钨矿表现为“上铜下钨”的垂向分带特征,而永平铜矿则以铜矿化为主。基于对比分析结果,文章提出永平铜矿深部找矿的重点方向和勘查建议,为类似矿床的勘查工作提供参考。Yongping Copper Mine and Zhuxi copper tungsten mine are located in South China block.In this paper,the tectonic background,stratigraphic lithology,orebody occurrence,ore fabric and surrounding rock alteration characteristics of the two mining areas are systematically compared.The results show that the two mining areas are controlled by the deep fault system and have similar orebody occurrence characteristics and ore fabric characteristics,but there are obvious differences in the alteration types of surrounding rock and mineralization zoning.The Zhuxi copper-tungsten deposit is characterized by vertical zonation of"upper copper and lower tungsten",while Yongping copper deposit is dominated by copper mineralization.Based on the results of comparative analysis,the paper puts forward the key prospecting directions and exploration suggestions of Yongping Copper mine,which can provide reference for the exploration of similar deposits.
