Abstract:

对东昆仑断裂带西大滩段进行了断错地貌填图和古地震探槽揭露,共揭露出9次古地震事件,它们的年龄分别为39090±2348aB.P.,27780±2360aB.P.,24100±1451aB.P.,19850±1690aB.P.,12670±714aB.P.,8980±544aB.P.,6380±388aB.P.,4425±265aB.P.和3030±182aB.P.。古地震重复间隔分别为11310±2880a,3680±2211a,4250±1879a,7180±1392a,3690±897a,2600±668a,1955±470a,1395±321a和3030±182a。结果表明,西大滩段晚第四纪古地震活动具有准周期性,其中7次古地震事件发生时间与东昆仑断裂带库赛湖段古地震事件的发生时间非常接近,这意味着东昆仑断裂带库赛湖段和西大滩段既可以独立破裂形成中强地震,也可以同时发生破裂形成强震。东昆仑断裂带的古地震活动历史对于认识该断裂的破裂特征和强震复发规律具有重要的意义。
