| 摘 要： | 娄里金矿床位于华北地台山西断隆与华北断拗两个Ⅱ级构造单元结合部位的武安凹断束中。金矿床在区域上主要受火山机构控制,矿体主要产于白垩系下统娄里组凝灰熔岩中。通过对娄里金矿床成矿流体包裹体的温度、气液相成分和盐度的测试和分析,估算成矿压力和深度,从而对金矿床类型和成矿流体来源进行了探讨。结果表明,娄里金矿床成矿温度低、盐度低、成矿压力小、成矿深度浅,矿床类型属于浅成低温热液矿床。流体包裹体氢氧同位素组成显示成矿流体位于岩浆水与大气降水之间,是岩浆水与循环的大气降水的混合。

| Abstract: | Louli gold deposit is located in the Wuan concave fault bundle at the conjunction of two second order tectonic units of Shanxi fault uplift and north china fault depression in the North China platform.Ore body occurs mainly in tuff of lower Cretaceous Louli Formation and is controlled by volcanic apparatus.This paper according to test of temperature,composition of the gas and liquid phase and salinity of the fluid inclusions are estimated the metallogenic pressure and depth and discussed the type and ore fluid source of the gold deposit.The results show that the gold deposit a epithermal low temperature hydrothermal deposit formed under low salinity,low pressure and shallow environment.Hydrogen and oxygen isotopic composition of the fluid inclusions is between magmatic water and meteoric water,a mixture of magmatic water and the circulating meteoric water. |
