摘要:

在鲜水河—小江断裂带上布设10个测区,每个测区布设4条土壤气测量剖面,共640个测点,跨断层测量了土壤气CO₂、CH₄、H₂、Rn和Hg的浓度,分析了土壤气的空间分布特征及其成因,讨论了土壤气地球化学特征与断层活动的关系。结果表明,①鲜水河—小江断裂带土壤气CO₂、CH₄、H₂、Rn和Hg的平均浓度分别为0.4%、12.0 ppm、5.3 ppm、13.53 kBq/m³、11.29 ng/m³; ②鲜水河断裂炉霍段、安宁河断裂冕宁—西昌段和则木河断裂上高土壤气浓度值表明,历史大地震离逝时间越短、近期小震活动性越强、滑动速率越高的断层,其裂隙发育程度越高,从而导致土壤气浓度也越高; ③鲜水河断裂雪门坎段和小江断裂北段低土壤气浓度值表明,历史强震离逝越久、现今地震活动性越弱、滑动速率低的断层,其裂隙发育程度越低,从而导致土壤气体浓度也越低。

Abstract:

The concentration of soil gases CO₂,CH₄,H₂,Rn,Hg in the Xianshuihe-Xiaojiang Fault Zone was measured across the Fault,the spatial distribution characteristics of these soil gases and their causes were analyzed,and the geochemical characteristics of the soil gases and the fault's activity were discussed.In April 2021,a total of 10 surveying areas were arranged in the Xianshuihe-Xiaojiang Fault Zone,and 4 surveying profiles were arranged in each surveying area for soil gas measurement,with a total of 640 survey points.The measurement results show that:① The average soil gas concentration of CO₂,CH₄,H₂,Rn,Hg in the Xianshuihe-Xiaojiang Fault Zone is 0.4%,12.0 ppm,5.3 ppm,13.53 kBq/m³ and 11.29 ng/m³,respectively.② The high values of the soil gas concentration in the Luhuo Section of the Xianshuihe Fault,in the Mianning-Xichang section of the Anninghe Fault and in the Zemuhe Fault show that the shorter the elapsed time of the historical large earthquake is,the higher the sliding rate of the Fault will be.The intenser the activity of recent small earthquakes is,the more developed the fault fissures will be,and the higher the soil gas concentration will be.The low values of the soil gas concentration of the Xuemenkan Fault in the Xianshuihe Fault Zone and the North section of the Xiaojiang Fault Zone show that the shorter the elapsed time of the historical large earthquakes is,the weaker the current seismicity of the Fault will be.The lower the sliding rate of the faultis,and the lower the development of the fault fissures is,the lower the soil gas concentration will be.
