| 摘 要： | 本文通过对红河断裂北段相态汞的构造地球化学特征研究,认为表生条件下土壤汞主要以氯化汞和硫化汞存在。可用土壤相态汞进行活动断层勘查,其中反映较好的有气态汞、总汞、氯化汞和硫化汞。红河断裂上部较高的气态汞含量反映其强烈活动性。本文最后讨论了表生条件下土壤相态汞的可能转化模式。

| Abstract: | In this paper, through a study on the tecto-geochemical characteristic of phase state Hg along the northern segment of Red River fault it suggested that Hg in the supergene soil is mainly existed in the form HgCl2 and HgS. The phase state Hg can be used to survey active faults, in which the gaseous state Hg, total Hg, HgCl2 and HgS serve as better reference data. The higher content oi gaseous state Hg in the upper part of Red River fault reflects the violent activity along the fault. Finally, a, probable transform model of phase state Hg in the supergene soil is discussed. |
