郯庐断裂带新沂—泗洪段土壤气Rn体积活度和CO2浓度特征研究

Abstract

Abstract: Concentrations of soil gases Rn and CO₂ were measured at 4 profiles in Jiangsu segment of Tanlu fault, the results show that the average concentrations of Rn observed at the four profiles are 22.9 kBq/m³, 35.5 kBq/m³, 40.2 kBq/m³ and 26.6 kBq/m³, and the average concentrations of CO₂ are 0.669%, 0.400%, 0.503% and 1.109% respectively. The concentration of soil gases Rn and CO₂ in the study area has a good consistency with the spatial distribution, which may be related to the fact that CO₂ is the carrier gas of Rn. A comprehensive analysis of soil gases Rn, CO₂ and the leveling data, indicated that the highest Rn concentration observed in Xiaodian section, which may be related to the adjustment of regional stress-strain. The results not only provide a reference for soil gas research, but also provide a reference of geochemical data for tectonic activities research in the study area.
