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0．81～0．99 g／cm3；成矿压力在105．99×105～342．10×105 Pa 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±7 Ma，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 ×105 ~342.10 ×105 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.
