摘要
对比研究了皖南西坑银多金属矿床中赋矿围岩蓝田组地层、成矿有关的花岗岩、矿石、矿床蚀变岩等地质体的稀土元素地球化学特征 ,借以示踪成矿物质来源。结果表明 ,西坑银多金属矿床成矿热液、成矿物质主要来源于花岗岩浆作用 ,成矿热液和富碳酸盐岩地层水岩反应使蚀变岩相对富集重稀土。
REE geochemical feature was studied by comparing ore with ore hosted Lantian group stratum, granite related to ore deposit, and altered rock, to trace metallogenic matter origin. The results indicate that metallogenic hydrothermal and metallogenic matter of Xikeng silver and multi metal ore deposit source from Yixian granite magma function, water rock reaction between metallogenic hydrothermal and rich carbonate stratum which results in HREE comparative enriching in altered rock.
