摘　　要：通过对水银洞超大型金矿赋存于Sbt（构造蚀变体）中的金矿石初步研究，表明该类型矿石物质组成较复杂，矿石有用组分除Au外，Ag—As—S皆达综合利用指标，有两件样品中Tl含量在0．0015％～0．0122％之间，达综合利用指标。矿石中的金以包裹金为主，暴露金次之，硫化物中金的分配率为40．07％，仅为金的较主要载体，而碳酸盐矿物和硅酸盐矿物中金的分配率则高达34．79％。Preliminary study on Sbt -hosted ores in the Shuiyindong super- large gold deposit, Guizhou Province indicates that there are complex constituents in the ores. Useful constituents are Au as well as Ag, As and S with higher contents above the comprehensive utilization index, and Tl contents of two ore samples are 0. 0015% and 0. 0122% , respectively, both of which are higher than the comprehensive utilization index. Gold in the ores are mainly inclusion gold and some exposure gold. The distributive rate of gold in the ore is 40.07% in sulfides and 34.79% in carbonate and silicate.
