| 摘 要： | 三道湾子金矿位于大兴安岭燕山期成矿带东南部,为中-低温火山热液型金矿床,矿石类型为贫硫石英脉型.通过对矿床地质特征、地球物理特征、地球化学特征、矿石类型、成矿期次、流体包裹体及稳定同位素地球化学特征的研究,初步确定了该矿床的找矿标志为贫硫石英脉,北西向张性断裂,硅化,Au、Ag为主(伴有As、Sb)的土壤地球化学异常,高电阻率异常,成矿温度为中-低温,含盐度中等,成矿流体以大气降水为主,具幔源硫.该标志对于在三道湾子一带寻找同类型金矿具有一定的指导意义.

| Abstract: | The Sandaowanzi gold deposit, located in the southeast of the Yanshanian Daxinganling metallogenic belt, is an epithermal-mesothermal volcanic type of quartz ore with poor sulfide. Study on the characteristics of geology, geophysics, geochemistry, type of ore, stages of mineralization, fluid inclusions and stable isotopes of the deposit, the main prospecting indicators for the deposit are determined as poor sulfide quartz vein, NW-trending tensile fault, sillicification, high resistivity electric field, soil anomalies of Au and Ag with As and Sb elements, low-medium ore-forming temperature, medium salinity, meteoric water-dominated ore-forming fluid and mantle-derived sulfur which are significant in searching deposits of the same type in the metallogenic belt. |
