双王金矿位于陕西省太白县西南部,矿床赋存于秦岭泥盆系地层中。双王金矿床8号、9号、7号、5号、6号、2号矿体内热液矿物流体包裹体系统研究表明:成矿早期、主成矿期和成矿后期包裹体均一温度主要范围分别为300～463℃、220～340℃和100～279℃。主成矿期成矿流体具有低盐度(2.1%～22.7%NaCleqv)、富CO2和含有N2、CH4等气体的特征。从矿区东部向西部成矿压力有逐渐降低的趋势,流体体系趋于开放。成矿流体来源较为复杂,以岩浆水和变质水为主,后期有大气降水的混入。包裹体的多样性及演化特征和角砾岩型矿化特征显示双王金矿床成矿流体具有不混溶性特征,成矿压力约为100～170 MPa。流体的减压沸腾是导致金沉淀成矿的重要原因。
The Shuangwang gold deposit is located in the southwestern part of Taibai County, Shaanxi Province, and the deposits occur in the Devonian strata in the Qinling Mountains. The fluid inclusions of hydrothermal fluids inclusions in No.8, No.9, No.7, No.5, No.6 and No.2 ore bodies of Shuangwang gold deposit show that during the early stage of metallogeny, the main homogenization temperature of the main ore forming and post-ore forming inclusions is mainly The ranges are 300 to 463 ° C, 220 to 340 ° C and 100 to 279 ° C, respectively. The main mineralization fluid has low salinity (2.1% ~ 22.7% NaCleqv), rich in CO2 and contains N2, CH4 and other gases. The pressure of mineralization gradually decreases from the east to the west of the mining area, and the fluid system tends to be open. The origin of ore-forming fluid is more complicated, mainly magmatic water and metamorphic water, with the mixing of atmospheric precipitation in the later period. The diversity and evolution of inclusions and the breccia-type mineralization show that the ore-forming fluid in Shuangwang gold deposit is characterized by immiscibility and the metallogenetic pressure is about 100-170 MPa. The decompression boiling of fluid is one of the important reasons leading to gold precipitation.
