Variation of soil gas 222Rn/220Rn concentration ratios along the Balçova–Narlıdere segment of the Izmir Fault

Year: 2025

Type: article

Abstract: The Balçova–Narlıdere segment of the İzmir Fault is an active tectonic region with high geodynamic significance. Soil gas radon (222Rn) and thoron (220Rn) concentration ratios were studied along this segment to evaluate their potential as geochemical indicators of fault activity. 222Rn concentrations ranged from 440 to 32,233 Bq/m3 and 220Rn from 328 to 29,367 Bq/m3. A special focus was on the 222Rn/220Rn ratio as a geodynamic precursor. 222Rn/220Rn ratios were analyzed specifically at locations where single gas anomalies were detected, allowing them to distinguish among different depths of the gas source and hence different fault processes.
