大平掌铜多金属矿床由块状硫化物矿体 (上部 )和细脉浸染状矿体 (下部 )组成 .前者的包裹体类型简单 ,均一温度、盐度和捕获压力较低 .后者以包裹体类型复杂、均一温度及捕获压力较高为特征 .其差异与成矿流体演化有关 .研究表明 ,成矿流体以富 K+、Na+、Cl-、SO2 - 4 、F-、CO2 和 CO为主 ,属中低温、中盐度的 K质溶液 ,主要来源于海水 ,并有深部岩浆水的混合
The Dapingzhang copper polymetallic deposit is composed of massive sulfide ore body (upper part) and veinlet disseminated ore body (lower part), with the former type of inclusions being simple and with homogenization temperatures, salinities and capture pressures lower, The results show that the ore-forming fluids are mainly K +, Na +, Cl-, SO2-4, F-, CO2 and CO , Is a medium and low temperature, salinity K solution, mainly from seawater, and deep magma water mixture
