武山铜矿床地质特征及成因分析

Geological Characteristics and Cause-Effect Analysis of Wushan Copper Deposit

武山铜矿地处扬子准地台中的下扬子坳陷带西段,位于九瑞铜矿田中部,为长江中下游重要的铜多金属矿床。在分析区域地质背景、矿区地质和矿床地质特征的基础上,结合矿区最新工作成果,对区内控矿因素进行了分析。通过对比分析南北矿带的关系,认为武山铜矿矽卡岩型铜矿带和似层状硫化物型铜矿带为同一岩浆活动期后热液作用下的产物,具有统一的内在联系。

Wushan copper deposit is located in the west of the lower Yangtze depression zone in the Yangtze quasi-platform and in the middle part of Jiurui copper mine field,which is an important copper polymetallic deposit in the middle-lower Changjiang River.Based on the analysis of regional geological background,geological characteristics of mining area and mineral deposit,and the latest work achievements of mine area,the paper analyzes the ore-controlling factors in detail.By comparing and analyzing the relationship between the north and south ore belts,it is concluded that the skarn type copper belt and the stratified sulfide type copper belt of wushan copper mine are the products of the ore fluid action after the same magmatic activity period,which have uniform internal relation.
