城门山铜矿地质特征及成因分析

The gate mountain copper mine geological characteristics and genetic analysis

经过对城门山铜矿矿体特征的分析和研究,结果表明,城门山铜矿是燕山早晚期阶段的中酸性钙碱岩浆的数次侵蚀造成的块状硫化物和矽卡岩型与斑岩型的铜矿床,这种矿床属于岩浆期后中低温热液铜矿床。

Through the analysis and study of the gate mountain copper orebody characteristics,the results show that the gate is a late stage of early yanshan mountain copper mine,several erosion caused by the acidic calcium alkaline magma massive sulfide type and skarn and porphyry copper deposit,this deposit belongs to magmatic period after low temperature liquid copper deposit.
