本文通过摸拟汞源在液相、固相和气相中的转化迁移实验,了解汞矿体及含汞的其它金属矿体处在潜水面下的还原环境和表生氧化环境中,汞源能否转化成气态汞而透过含水层障碍进入气相的问题,并结合几个典型矿床的壤中汞气异常形成机理、汞的存在形式、主要迁移形式和途径等一系列有关形成机理的问题进行了探讨,取得了对壤中汞气异常评价的理论依据。此外,对影响壤中汞气异常的矿床地质条件、气候变化和采样工作方法等主要因素及其解决方法均进行了初步探讨。总之,本项研究成果,对于改进和提高壤中汞气测量的找矿评价效果具有一定的指导意义。
In this paper, by simulating the transformation and migration experiments of mercury sources in liquid, solid and gas phase, we know that the mercury sources and other metallogenic bodies containing mercury exist in the reducing environment and epoxide environment under the diving surface. Whether it transforms into gaseous mercury or not and enters the vapor phase through obstacles of aquifer, and combines with the formation mechanism of mercury in the soil of several typical deposits, the existing forms of mercury, the main migration forms and ways and so on to a series of problems related to formation mechanism In order to explore, a theoretical basis for the evaluation of abnormal mercury gas in the soil has been obtained. In addition, the main factors affecting the geological conditions, climate change and sampling methods affecting the mercury gas anomalies in the soil and their solutions were discussed. In conclusion, the results of this study are of guiding significance for improving and improving the prospecting evaluation of soil mercury measurement.
