断层泥吸附气体特征与断层活动性关系初步研究

断层带中断层气异常测量作为气体地球化学方法之一,已应用于地震预报和断层活动性研究.断层泥是断层活动历史的直接记录,为了探索断层泥中的吸附气体与断层活动性之间的关系,对大柳树地区的断层泥取样,进行室内脱气和气体组分测定,分析了不同特征断层泥吸附气体质量浓度变化的规律,初步建立了断层泥吸附气体组分与断层泥测年值之间的相关方程,并计算了误差.结果表明断层泥吸附气体与断层特征和活动性关系密切.

Initial research on the relationship between absorption gases of fault gauge and fault activity

As one of the gas geochemistry methods, the determination of the anomalies of fault gases in fault zones has been applied to the research of earthquake forecast and fault activity. The fault gauge is the direct record of the history of fault activity. To study the relationship between absorption gases of fault gauge and fault activity, samples were taken from Daliushu area. The gases were taken off and determined. In order to study the law between the different characteristics of fault gauge and the content change of absorption gases, we initially set up the relevant equations between the absorption gases and the dating of fault gauge, and also calculated the error rate. The results showed that the absorption gases of fault gauge are in close relation with fault characteristics and activity.
