池州东湖铜矿地质特征与典型矿床比较研究

Comparative Study on Geological Characteristics and Typical Deposits of Donghu Copper Mine in Chizhou

池州东湖铜矿是安徽沿江成矿带主亚带贵池成矿区一处小型矽卡岩型铜铁矿床,矿区上覆第四系、白垩系浅覆盖层,大地构造位于扬子陆块前陆盆地南部边缘,紧邻前陆南缘对冲带。东湖岩体为燕山早期中酸性岩类侵入体,发育侵入角砾岩。通过与姚家岭铜铅锌矿、茶亭铜金矿比较研究,发现东湖铜矿有姚家岭铜铅锌矿、茶亭铜金矿相似的成矿背景和控矿因素,因此应加强在贵池地区红层覆盖区的找矿工作。

The Donghu copper deposit in Chizhou is a small skarn copper-iron deposit in the Guichi metallogenic area of the main subbelt of the Yangtze River metallogenic belt in Anhui Province,with shallow Quaternary and Cretaceous overlying strata,and the geotectonics are located in the southern margin of the Yangtze block Foreland basin,close to the southern margin of the Foreland.Donghu rock body is an intrusive body of intermediate-acid rocks in the early Yanshanian period,and intrusive breccia is developed.Through the comparative study with Yaojialing copper-lead-zinc deposit and Chating copper-gold deposit,it is found that the Donghu copper deposit has similar metallogenic background and orecontrolling factors,so the prospecting work in the red bed cover area of Guichi area should be strengthened.
