摘要
安徽宣城狮子山铜(钼)矿床位于扬子陆块北缘江南过渡带内,狸桥—敬亭山复背斜北部,区域成矿地质条件优越。结合该区地质工作成果,详细讨论了狮子山铜矿成矿地质背景及矿床地质特征,并对矿床成矿作用过程及矿床成因进行了分析。研究表明:根据矿床物质组合及其围岩蚀变特征,成矿过程主要分为矽卡岩阶段、石英硫化物阶段、碳酸盐阶段、氧化作用阶段等4个成矿阶段,矿床成因属接触交代—热液矽卡岩型黄铜矿、辉钼矿矿床。
Xuancheng Shizishan copper( molybdenum) deposit in Anhui Province is located in the Jiangnan transition belt at the north margin of Yangzi continental block,and it is also distributed in the north of Liqiao-Jingting complex anticline. The regional metallogenic conditions is good. Based on the geological working results of the area,the metallogenic geological background and deposit geological characteristics of the area are discussed,and the metallogenesis and deposit genesis are studied in depth. The study results show that according to the mineral combination and surrounding rock alteration characteristics,the metallogenic process can be divided into the stages of skarn,quartz-sulfide,carbonate phase and oxidation phase,the genesis of the deposit is belongs to contact metasomatic-hydrothermal skarn chalcopyrite and molybdenum deposit.
