【摘要】：在六盘山东麓断裂带布设8条测量剖面,现场测量了土壤气Rn浓度及通量,来讨论六盘山东麓断裂带逸出气氡浓度特征及其与构造活动性间关系。测量结果表明:8个测区测量的气Rn浓度平均值在23.88~66.34kBq间,通量在2 194~14 091Bqm-3s-1间。断裂带土壤气Rn浓度平均值在空间分布上,自北向南逐渐增大,由44.61kBq升高至66.34kBq,到断裂带南段西贤村、刘店村两个剖面Rn浓度平均值减小,这可能是由空间上断裂活动性差异引起的。
[Abstract]:In order to discuss the characteristics of radon concentration in escape gas and its relationship with tectonic activity in the eastern foot of Liupanshan fault zone, eight survey sections were set up, and the concentration and flux of soil gas rn were measured in situ. The measured results show that the average concentration of rn in the gas measured in the 8 areas is between 23.88 and 66.34 kBq, and the flux is in the range of 2 194 ~ 14 091Bqm-3s ~ (-1). The average rn concentration of soil gas in fault zone increased gradually from north to south from 44.61 kBq to 66.34 kBq. to Xixian village in the south of fault zone, the average rn concentration of two sections of Liudian village decreased. This may be caused by the spatial difference in fracture activity.
