近几年来,为解决厚层覆盖区常规化探找矿效果不佳的问题,我们试验研究了壤中汞气测量方法。虽然在各类覆盖区,壤中汞气测量取得较好的找矿效果,但因该方法干扰因素多,特别是易受气候因素的影响,结果导致分析误差大、重现性差,不同季节的测量结果难以对比评价等。通过对壤中汞气异常形成机理的研究,发现含矿断裂上的土壤比非含矿断裂上的土壤含有更多的Hg、HeCl和HgCl_2,並且土壤中这种迭加吸附相态汞异常,主要来源于隐伏矿体。这就为地球化学探矿提供了理论依据。
In recent years, in order to solve the problem of poor prospecting effect of conventional geophysical prospecting in thick overburden areas, we have experimentally studied mercury gas measurement methods in soil. Although in all kinds of coverage area and soil, the mercury gas measurement has a good prospecting effect, but because of the interference of many factors, especially the susceptibility to climatic factors, the results lead to large analysis error, poor reproducibility, different seasons Measurement results are difficult to compare evaluation. Through the study on the formation mechanism of mercury anomaly in the soil, it is found that the soil on the ore-bearing fault contains more Hg, HeCl and HgCl 2 than the soil on the non-ore-bearing fault and this superimposed adsorption of phase mercury in the soil is abnormal, Mainly from hidden ore body. This provides a theoretical basis for geochemical exploration.
