武山铜矿地处长江断裂南侧的九江-瑞昌构造带中心部位,发育于横立山-黄桥向斜的北翼.不整合面及武山岩体接触带是矿体赋存的主要部位;上泥盆统五通组含砾石英砂岩和中石炭统黄龙组白云质灰岩之间的层间断裂带、中石炭统黄龙组和下二叠统栖霞组灰岩的层间断裂带控制块状多金属硫化物体的成生与富集,而武山岩体与石炭系、二叠系灰岩、灰岩捕虏体的接触带则形成夕卡岩型矿体;在武山岩体和石英砂岩接触部位则难以形成工业矿体.在研究断裂构造、接触带构造、褶皱构造和围岩组成特征基础上,预测在标高-1 100 m之上,武山岩体与灰岩的接触带中仍有较好的找矿前景,而在武山岩体与泥盆系、志留系巨厚碎屑砂岩的接触部位则矿化较差.

Wushan copper deposit is situated at the center of Jiujiang-Ruichang tectonic belt on the southern side of Yangtze river fracture and on the northern limb of Henglishan-Huangqiao syncline. Ore bodies occur at the uncoformity plane and the contact zones of Wushan intrusive body. The interformational fractural zones between the conglomeratic quartzite of Wutong formation of Upper Devonian Series and the dolomitic limestone of Huanglong formation of Middle Carboniferous Series and between Huanglong formation of Middle Carboniferous Series and limestone of Qixia stage of Lower Permian Series control the enrichment of massive polymetallic sulfide and formation of the ore bodies. Contact zones between Wushan intrusive body and limestone of Carboniferous System and Permian System and xenoliths control skarn ore bodies. No industrial ore body occurs at the contact zones between Wushan intrusive body and the quartzite. Based on study of characteristics of fracture, contact zone and folding and the wall rock composition it is predicted that the contact zone between Wushan intrusive body and limestone above -1100m level is prospective for ore exploration and less prospective at the contact zones between Wushan intrusive body and tremendous thick clastic sandstone of Devonian and Silurian Systems.
