摘要
本文对桂西北几个微细浸染型金矿床研究表明：Tl在矿石中富集，K／Tl、Ba／Tl比值，在矿石中明显低于围岩，Tl含量、K／Tl、Ba／Tl比值离差小，变化稳定，利用他们作为指示元素及特征比值寻找微细浸染型金矿床是一条可行途径。
In the microfine disseminated gold deposits in northwestern Guangxi, thallium is enriched in ores with K/Tl and Ba/Tl ratios being lower in the ores than in the wallrocks. moreoverl because of small coefficients of variation for thallium contents and K/Tl, Ba/Tl ratios, it is plausible that Tl contents and K/Tl and Ba/Tl ratios can be used as indicators for disseminated gold deposlts.
