壤中吸附相态汞测量,是近几年发展起来的一种化■新方法。该方法在常规化探找矿效果不佳的厚层基岩覆盖区和厚履运积物覆盖区,已显示出较好的找矿效果,许多研究者已作过报道:实践表明,该方法的影响因素虽比壤中气汞测量要少,但仍不可忽视,否则会影响找矿效果。近几年来,我们对壤中吸附相态汞(简称壤中汞量)测量方法的影响因素作了探讨,在识别和消除部分干扰因素、正确评价壤中汞量异常方面做了一些尝试,取得了点滴经验,现简介如下。 (一) 地质影响因素 Adsorption of mercury in the soil by mercury measurement is a new method developed in recent years. This method has shown good prospecting effect in thick bedrocks and thick bedrocks covered by unconventional geochemical exploration, which has been reported by many researchers. Practice shows that this method Although the influencing factors are less than those of mercury in soil, they can not be neglected, otherwise, the prospecting effect will be affected. In recent years, we have discussed the influencing factors on the measuring method of mercury in the soil, and made some attempts to identify and eliminate some of the disturbing factors and correctly evaluate the mercury in the soil. A bit of experience, are briefings are as follows. (A) Geological factors
