巴塘断裂氡气异常变化特征及其指示意义
Variation characteristis of radon gas anomaly in Batang fault and its indicative significance:A case study of Huangcaoping area
摘要
Abstract
Batang fault constitutes a critical segment of the western boundary fault of Sichuan-Yunnan rhombic block,and its activity has attracted significant attention.Soil radon gas measurement has been widely used in the reconnaissance survey of active faults.Huangcaoping area,crossed by Batang fault,was taken as the research ob-ject,and the means of field geological survey,soil radon gas measurement and UAV mapping were used to dis-criminate 5 secondary faults and seismic ground fissure in the study area.Fault F1 and the surface rupture S1,S2 are small in development scale,shallow in burial depth,and steep in occurence.Fault f,is in small scale,dip-ping to the southeast with a high dip.Fault f2 is a medium scale fault with a slightly gentle dip,dipping to the northwest,which is speculated to be the eastern boundary of Batang fault.The radon gas measurement anomaly corresponded well to the distribution characteristics of the faults in Batang fault,and the radon gas measurement method could determine the position of hidden faults in Batang fault more quickly and effectively.This method could provide references for the next step of fault activity research and historical earthquake research.关键词
