摘要
东峰顶金矿受断裂破碎带控制，矿石中主要矿物成分有石英、黄铁矿、重晶石及褐铁矿，其标型特征具成因和找矿意义。成矿流体为中低温、低盐度、弱酸性、低氧逸度和硫逸度。成矿物质主要来源于基底太古界变质岩系。表生作用使金的品位、成色获得大幅度提高。
The Dongfengding gold deposit is controlled by faulted zones. Its major mineral compositions are quartz, pyrite, barite and limonite, whose typomorphic characteristics have significance of genesis and prospecting. The ore-forming fluid is of medium-low temperature, low salinity, and low fugacity of O2 and S2. The metallogenic substance mainly comes from the Archeozoic metamorphic rock series in basement. Supergenesis makes the grade and fineness of gold increase greatly.
