摘　　要：以红花沟金矿莲花山矿区５１号脉群为主要研究对象，对含金石英脉中的流体包裹 体进行了均一温度、冰点的测定，并对化学成分分析结果进行了计算．最后得出此矿床得成 矿温度范围为： １００～３２０℃，成矿流体盐度为中低值。成矿流体为Ｎａ（Ｋ）Ｃｌ－Ｈ_２Ｏ－ＣＯ_２ 型．成矿元素金是在弱酸－中性的环境中，以氯、硫氢络合物的形式迁移．矿源层为太古代 的变质岩，成矿流体主要来源于大气降水，成矿过程中可能有少量的岩浆水的加入．该矿床 属于中－低温浅成石英脉型金矿床．Liang Junhong Yao Yuzeng Jin Chengzhu, Wang Jianguo Abstracr:The paper includes the determination of homogenization temperature and ice point (salinity), analysis of chemical composition, and draws conclusions: the temperature scope of mineralizatioll is between 100 -320 ℃, the salinity of the ore-forming fluid is medium-low, the fluid type attributes Na(K)Cl -H_2O -CO_2, gold of metallogenetic element migrates as the sulfurhydride complex in. incompetent acid and neutral condition. Archaeozoic metamorphic rock are regarded as the original rock, atmospheric water becomes the main fluidogent ics, heat and volatile are provided by Hercynian-Yanshan magmatisim. The genetic type of ore district is medium-low temperature and epithermal quartz veins.
