| 摘 要： | 文中介绍了北京南口—孙河断裂带上白浮断层土壤气四个不同集气深度H_2/Ar,N_2/Ar,CO_2/Ar,~4He/~(20)Ne,~4He/~(40)/Ar,~(40)Ar/~(36)Ar比值与地震活动,降雨等的关系,得到各项指标的变化与地震的发生具有一定的关系,但受季节变化的影响。通过断层剖面的工作,证明该断层具有较强的活动性。

| Abstract: | In this paper the ratios of H2 / Ar, N2 / Ar, CO2 / Ar, 4He / 20Ne,4He / 40Ar, 40Ar /36Ar in the soil gases from 4 different depths along Baifu fault, which is located on the Nankou-Sunhe fault zone, north of Beijing are introduced, and the relation between those ratios and seismicity, rainfall is also discussed. The research result indicates that there is a certain correlation between the earthquake occurrence and variation of the above-described ratios, but the season change would effect the ratios of soil gases. Study on fault profiles reveals that the Baifu fault has relatively strong activity. |
