  • 摘要: 断层土壤气是揭示断层性质和构造活动的重要地球化学手段，亦是研究断裂带释放气体对环境影响的重要观测途径.本文通过安宁河断裂带冕宁地区春季、夏季和秋季的三期断层土壤气观测，获取了Rn、CO2和Hg的浓度和分布特征.研究结果表明，安宁河断裂带冕宁地区地下气体Rn、CO2和Hg释放具有不均匀性，土壤气测线从西至东主要有3个土壤气体异常区段，可能揭示出安宁河断裂带上的3组主要破碎带位置.不同季节下，土壤气CO2和Hg浓度具有差异性，与温度和降雨有一定关系，显示出CO2和Hg浓度的季节效应.在土壤气Rn、CO2和Hg浓度较高的区域，居民生活应采取相应防护措施.本文结果为分析断裂带释放气体特征及对环境和生活的影响提供了地球化学参考依据.
    Abstract: Fault related soil gas is an important geochemical method to reveal fault properties and tectonic activities, and it is also used to study the impact of fault degassing on the environment. In this paper, the concentration and distribution characteristics of soil gas Rn, CO2 and Hg were obtained in spring, summer and autumn in Mianning area of the Anninghe fault zone. The results showed that the underground gas Rn, CO2 and Hg in the Mianning area of the Anninghe fault zone was heterogeneous. There were three soil gas concentration abnormal sections along the soil gas survey line from west to east, which might reveal the locations of three major fracture zones of the Anninghe fault zone. The concentrations of soil gas CO2 and Hg varied in seasons, and were probably controlled by temperature and rainfall, showing the seasonal effects. Protective measures should be taken in areas with high concentrations of Rn, CO2 and Hg. The results provided a geochemical reference for analyzing the characteristic of gas released from the fault zone and its impact on the environment and human life.
