| 摘 要： | 为研究安阳南断裂带土壤气体地球化学特征及构造地球化学背景，采用野外流动测量的方法对安阳南断裂带宗村段开展2期土壤H2和Rn的重复观测。结果表明，第1期H2和Rn的浓度范围分别为（0.66~58.56）×10-6 和15~123 kBq/m3，背景值分别为6.87×10-6和52.49 kBq/m3；第2期H2和Rn的浓度范围分别为（0.36~29.73）×10-6和28.2~103 kBq/m3，背景值分别为0.89×10-6和47.49 kBq/m3。2期H2和Rn的测量结果均显示，在距测量起点210~300 m处气体浓度出现高值异常，气体在断裂带附近较为富集，对断层位置有一定的指示作用，利用断层气H2和Rn探测隐伏断裂的浅层位置在该区具有可行性。

| Abstract: | To study the geochemical characteristics of the gas in the soil layer and the tectono-geochemical background, which was reflected by fault gas in the south Anyang fault zone, two periods field measurement are used to analyze the concentration distribution of soil H2 and Rn in the one observation line of Zong village. The results show that the distributions of H2 and Rn concentration in the first phase range from 0.66 to 58.56×10-6 and from 15 to 123 kBq·m-3, respectively. The background values of H2 and Rn concentration are 6.87 ×10-6 and 52.49 kBq·m-3, respectively. The concentration distribution range of H2 and Rn in the second phase range from 0.36 to 29.73×10-6 and from 28.2 to 103 kBq·m-3, respectively, with background values of 0.89 ×10-6 and 47.49 kBq·m-3, respectively. In two phase measurement, a strong anomaly of H2 and Rn appears at 210 to 300 m, with anomalous values located near the fault zone, which could effectively indicate the fracture location. It is feasible to use fault gas H2 and Rn to detect the location of concealed faults in this area. |
