九江城门山铜矿新发现矿体特征分析及找矿潜力预测

Characteristics Analysis and Prospecting Potential Prediction of Newly Discovered Ore Bodies in the Jiujiang Chengmenshan Copper Deposit

城门山铜矿床是我国著名的大型铜矿之一,属长江中下游铁铜成矿带大冶九江成矿亚带的重要组成部分。该矿床具有斑岩型、矽卡岩型、块状硫化物型“三位一体”成矿模式特征。通过对城门山铜矿床北区新发现XCu矿体产出形态、赋存位置及矿石质量等矿体特征的对比分析与研究,进一步对矿区内成矿分带模式进行了总结。最终认为新发现XCu矿体具有成中大型矿体的潜力,且城门山铜矿床北区及其外围找矿远景巨大。该发现对矿区内下一步找矿工作具有较好的指示作用。

Chengmenshan copper deposit is one of the famous large copper deposits in our country.It is an important part of the Daye Jiujiang metallogenic subzone of the iron and copper metallogenic belt in the middle and lower reaches of the Yangtze River.The deposit has the characteristics of porphyry,skarn and massive sulfide type.By comparing and analyzing the characteristics of ore bodies,such as the occurrence form,occurrence location and ore quality of XCu ore body discovered in the northern part of the Chengmenshan,the metallogenic zoning pattern of the mining area is further summarized and optimized.Finally,it is believed that the discovered XCu ore body has the potential of medium to large orebody.and the northern area and its periphey of Chengrmenshan copper deposit have a great prospect.Furthermore,the discovery has a good indication for the next prospecting work in the Chengmenshan copper area.
