对印度尼西亚金马石金矿的普穗蒙古、金巴克和金盆维特3个矿段的矿石中石英流体包裹体进行岩相学观察和显微测温,结果表明:包裹体类型简单,以富液相气液两相包裹体为主,属于NaCl-H2O流体体系;包裹体均一温度集中在240~320℃之间,盐度峰值为14%~17%;流体密度峰值为0.85~0.95 g/cm3,流体的压力值介于4.1~46.8 MPa之间,相应的成矿深度为150~1730 m,总体具有浅成低温热液矿床的特点。根据地质特征和矿石的石英流体包裹体特征推断,金马石金矿是高硫型浅成低温热液矿床,可能属于斑岩-(高硫型)浅成低温热液型成矿体系;Au沉淀以流体混合作用为主。
The petrographic inclusions in the quartz ore inclusions of the three gold mines in Puzong Mongolia, Jabuck, and Jinpenwett of the Kinmen-Smek gold deposit in Indonesia were observed and microscopic measured. The results show that the types of inclusions are simple, Phase fluid inclusions in the gas-liquid two-phase inclusions, which belongs to the NaCl-H2O fluid system. The homogenization temperature of the inclusions is concentrated in the range of 240-320 ℃ and the salinity peak is 14-17%. The peak value of the fluid density is 0.85-0.95 g / cm3 , The pressure of the fluid is between 4.1 ~ 46.8 MPa, the corresponding mineralization depth is 150 ~ 1730 m, and generally has the characteristics of epithermal deposits. According to the geological characteristics and the quartz fluid inclusions of ore, it is concluded that the Jinmashi gold deposit is a high-sulfur epithermal deposit that may belong to a porphyry (high-sulfur) epithermal-type hydrothermal metallogenic system. Au deposits The main role of fluid mixing.
