本文对南非克莱克斯多普金矿田的瓦尔砂金矿的94个不同金粒样品进行Au、Ag及Hg的含量分析,结果表明:Au、Ag及Hg的含量分别为重量的80～95%、4～1 8%及0.5～4%,平均含量分别为:A u90%,Ag 8%及Hg 2%。金粒是同类的,但在单一样品的不同金粒之间,以及不同样品的平均组分之间,其成分相差很大。因此,金粒组分变化并不适合一种简单的模式—物源或变质均一化作用来控制。
In this paper, the content of Au, Ag and Hg in 94 different gold samples from the Valle Gold mine in the Klerksdorp gold field in South Africa was analyzed. The results showed that the contents of Au, Ag and Hg were 80-95 %, 4 ~ 18% and 0.5 ~ 4% respectively, the average contents are: A90%, Ag8% and Hg2%. Gold particles are homogeneous, but their composition varies widely between gold particles of a single sample and between the average components of different samples. Therefore, the changes in the composition of the gold particles are not suitable for a simple model - the source or metamorphism to control the metamorphism.
