Abstract:: Based on the distribution of the concentration of the soil gas Rn and CO₂ in the Ruichang-Wuning Active Fault Zone obtained by cross-fault observation in the field,we analyze the geochemical characteristics of Rn and CO₂ in the Fault Zone,and reveal the relationship between the geochemical characteristics of the two soil gases and the Fault Zone.The results show that the strong correlation of Rn and CO₂ concentration indicates that in the Fault Zone Rn migrates to the shallow surface along with CO₂.The peak concentrations of Rn and CO₂ soil appear near the Fault Zone.The concentration of Rn and CO₂ in the middle of the Guilinqiao survery line is obviously higher than that at both ends of the line,while the average concentrations in the middle and both ends of the Wujiafan survey line are relatively close.The concentrations differ spatially mainly because of the different degrees of fault healing after the earthquake.The concentration of Rn in both the two survey lines is high,and the b-value scanning shows that the stress in the study area is increasing,indicating that the Fault activity is strong.This suggests that the concentration of Rn is closely related to the activity of the Ruichang-Wuning Active Fault Zone.
