呼和浩特地区隐伏断层土壤气氡、 汞地球化学特征

Abstract

Abstract: The geochemical characteristics of Rn and Hg, and the methods for detecting buried faults as well, are discussed on the basis of the concentrations of Rn and Hg in soil gas. The concentrations of Rn and Hg were measured at 2014 sites along eight profiles across three buried faults in the Hohhot region. The results indicate that the background values of Rn and Hg concentrations range from 2238.7 to 3715.4 Bq/m³ and from 21.1 to 79.4 ng/m³, respectively. Anomalies of Rn and Hg concentrations in soil gas along the eight geochemical profiles are as high as 1.7~10.3 folds of background values over the buried faults, which strongly demonstrate that the geochemical characteristics of Rn and Hg in soil gas can well reflect the locations of buried faults.

Key words: Rn, Hg, Buried fault, Soil gas, Hohhot region
