本研究成果建立在对产于晚太古代绿岩带中的55个中温热液金矿床的137个大样的约70种元素的分析基础上。尽管这些矿床在成矿省和单个矿床的元素共生组合和富集上有明显差别,但总体来看,Au、Te、S、As、W、Bi、Ag和Se依然是金矿勘探中最重要的元素。Te、As、Bi和Se的富集一般大于玄武岩平均丰度的1000—100倍,而W、S和Ag的富集系数则为100—10。Sb、B、Mo、Cu、U、Hg、Pb、Sn、Cr和Co只在局部显得重要。在大量数据中,只有Te、Bi和Ag示出与Au有密切的关系,表明它们大概同时沉淀,因此是最适于详勘的元素。其他元素可能局部与Au有关,但它们的大量沉淀不是在Au之前,就是在Au之后。这些元素可在Au矿周围形成大范围的晕圈,因此最适用于区域勘查。
The results of this study are based on the analysis of about 70 elements of 137 large samples of 55 intermediate-temperature hydrothermal gold deposits dating from the Late Archean greenstone belt. Although these deposits are significantly different in the elemental symbiotic assemblages and enrichments of metallogenic provinces and single mineral deposits, Au, Te, S, As, W, Bi, Ag and Se are still the most important Elements. The enrichment of Te, As, Bi and Se is generally greater than 1000-100 times the average abundance of basalts, while the enrichment coefficients of W, S and Ag are 100-10. Sb, B, Mo, Cu, U, Hg, Pb, Sn, Cr and Co are only important locally. Of the large amount of data, only Te, Bi, and Ag show close relationships with Au, indicating that they are precipitating at about the same time and therefore are the most suitable elements for detailed investigations. Other elements may be locally associated with Au, but their bulk precipitation is not before Au, just after Au. These elements form a wide range of halo around the Au ore and are therefore most suitable for regional exploration.
