摘要
本文研究了水银洞金矿床碳酸盐岩型矿石，表明含金黄铁矿具“三层式”结构特点，金赋存于沿自形半自形沉积型黄铁矿内核生长成的含砷黄铁矿环带中，含砷黄铁矿环带中金的含量达600×10^-6～1800×10^-6，高金含量与砷含量3％～6％、锑含量0．025％～0．075％、铜含量0．025％～0．075％、硫含量48％～53％相对应。Tl含量低于检出限，看不出Au成矿与Tl之间有何关系。
Detail study on carbonate - type ores in the Shuiyindong gold deposit shows that auriferous pyrite is characterized by ＂three - floor pattern＂, the gold is hosted in arsenic - bearing pyrite zone generating along hypidiomorphic and automorphic sedimentary pyrite kernel, which high content amount to 600×10^-6～1800×10^-6 in arsenic -bearing pyrite zone is in content equivalent to arsenic of 3 to 6 percent, antimony of 0. 025 to 0. 075 percent, copper of 0. 025 to 0. 075 percent and sulfide of 48 to 53 percent. Thallium content is lower than detection limit that is not obviously related to gold mineralization
