| 摘 要： | 马家窑金矿床是胶东地区比较典型的石英脉型金矿床代表，属中低温热液矿床，成矿流体盐度较低，气相成分以H2O，CO2为主，其次是Na^＋，Ca^＋和Cl^-，K^＋和F^-较贫，流体的成分与大气降水热液相类似。成矿流体的H，O同位素值则反映大气降水在不同温度和不同水／岩值条件下与栖霞超单元回龙夼单元交换后的分布特征，认为马家窑金矿床的成矿热液属大气降水成因。

| Abstract: | Majiayao gold deposit is the representative of typical quartz vein type gold deposits, which blongs to low temperature thermal deposit. Salinity of ore - forming fluid is rather low, and vapor phase compositions are majorly composed of H2O and COE, accompanying with Na^＋ , Ca^＋ , K^＋ and F^-. Components of fluid is similar with meteoric water. Isotopic values of H and O in ore - forming fluid reflect distribution characteristics of meteoric water under different temperature, water and rock values after being changed with Huilongkuang unit of Qixia superunit. It is regarded that ore - forming hydrothermal solution of Majiayao gold deposit is meteoric water hydrothermal solution. |
