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．
The main study object is the pulse train of No. 51 in Honghuagou gold mine Lianhuashan mine area. The fluid inclusions in the gold-bearing quartz vein were measured for the homogenization temperature and freezing point. The results of chemical composition analysis were also calculated. The conclusion is that the mineralization temperature of this deposit is in the range of 100-320 ℃ and the salinity of ore-forming fluid is low. The ore-forming fluid is Na (K) Cl-H 2 O-CO 2 type. Metallogenic elemental gold migrates in the form of chlorine and sulfur-hydrogen complexes in a weak acid-neutral environment. The source rock is Archean metamorphic rocks, and the ore-forming fluids are mainly derived from atmospheric precipitation. There may be a small amount of magmatic water in the ore-forming process. The deposit belongs to medium-low temperature epithermal quartz vein type gold deposit.
