小秦岭地区与金矿成因有关的燕山期文峪花岗岩及其派生石英脉中发育了非常丰富的ＣＯ２－Ｈ２Ｏ包裹体，其流体为富含ＣＯ２的低盐度（＜１０％ＮａＣｌ）流体，这与含金石英脉内的包裹体类型及金矿成矿流体性质上十分相似。与金矿成因无关的华山岩体内包裹体类型则为水溶液包裹体，流体性质为贫ＣＯ２的低盐度流体。与金矿有关，但其周围矿化很差的娘娘山岩体内ＣＯ２－Ｈ２Ｏ包裹体数量很少。因此，ＣＯ２－Ｈ２Ｏ包裹体可以作为与金矿成因有关的花岗岩体关联程度的判别标志，而ＣＯ２－Ｈ２Ｏ包裹体的丰度可以作为金矿床品位和规模评价及成矿前景展望的依据
In the Xiaoqinling area, the Yanshanian Wenyu granite and its derived quartz veins related to gold genesis have very rich CO2-H2O inclusions and their fluids are CO2-rich low-salinity (<10% NaCl) fluids It is very similar to the type of inclusions and the metallogenetic fluid in the gold bearing quartz vein. The type of inclusions in Huashan Rock, which has nothing to do with the origin of gold deposits, is an aqueous solution inclusions, and the properties of fluids are CO2-depleted low-salinity fluids. In relation to the gold deposit, the amount of CO2-H2O inclusions in the Niangniangshan rock, which is poorly mineralized around it, is small. Therefore, the CO2-H2O inclusions can be used as discriminant markers for the association degree of granite bodies related to gold genesis, and the abundance of CO2-H2O inclusions can be used as the basis for evaluating grade and size of gold deposits and prospect of metallogenic potential
