摘要
对铲子坪金矿床流体包裹体、氢氧同位素和石英包裹体Rb-Sr年龄进行了分析研究.结果显示,包裹体均一温度范围是147~310℃;盐度值主要集中于10%~11%;密度范围为0.81~0.99g/cm3;成矿压力在105.99×105~342.10×105Pa之间;早中期阶段成矿流体以岩浆水为主,晚期阶段成矿流体以大气降水为主;Rb-Sr年龄等时线年龄为244±7Ma,表明其成矿时代为印支期.
This paper studies the fluid inclusion, the hydrogen and oxygen isotopes and the quartz inclusions Rb - Sr age determination of Chanziping gold deposit. It shows that the homogeneous temperatures rang from 147-310 ℃. The salinity values mainly focus on the 10% -11% ; the density ranges from 0.81 0. 99 g/cm3 ; the metallogenic pressure is between 105.99× 10^5 - 342.10 × 10^5 Pa. The early and middle stages of ore- forming fluid are mainly magmatic water, while in the later stage it is atmospheric precipitation. The isochron age of Rb - Sr age is 244 ＋ 7 Ma, showing that the metallogenic epoch is the indosinian stage.
