摘要

为明确土壤氡气异常与活动断层构造地貌的响应关系，探索隐伏断裂的快速预测方法，在川西阿坝南断裂盆地段开展了土壤氡气测量和无人机微地貌扫描研究。断裂活动形成的氡气异常区和构造特征与隐伏断裂分布区高度一致。结论是，土壤氡气测量与构造地貌分析相结合，可以快速准确地预测被第四纪沉积物覆盖的隐伏断裂。

Radon gas and geomorphic analysis as supportive tools for fault exploration: an example from the Aba South Fault basin, western Sichuan

Clarifying the response relationship between soil radon gas anomalies and active fault tectonic geomorphology, and to explore a rapid prediction method for concealed fractures, soil radon gas measurements and unmanned aerial vehicle micro-geomorphic scanning were carried out in the basin section of the Aba South Fault in western Sichuan. The areas of radon gas anomalies and tectonic features formed by fracture activities are highly consistent with the distribution areas of hidden fractures. It is concluded that the combination of soil radon gas measurements and tectonic geomorphologic analysis can rapidly and accurately predict hidden fractures covered by Quaternary sediments.
