| 摘 要： | 色尔腾山山前断裂得令山以东段属全新世活动断裂。距今约 30ka以来 ,断裂上升盘的平均抬升速率为 :大佘太段 0 19mm/a ,乌兰忽洞段 0 2 0mm/a。探槽揭露 ,大佘太段 ,约 32kaBP以来 ,发生过 4次古地震事件 ,事件发生时间依次为 (316 90± 1770 ) ,(2 30 0 0± 132 0 ) ,(15 42 0± 870 ) ,(74 40± 4 40 )aBP ,相应的位移量分别为 2 6 ,1 6 ,2 2 ,1 4m ;乌兰忽洞段 ,约 2 5kaBP以来 ,也发生过4次古地震事件 ,事件发生时间依次为 (2 5 130± 14 30 ) ,(14 5 70± 82 0 ) ,(116 6 0± 6 5 0 ) ,(72 2 0± 4 0 0 )aBP ,相应的位移量分别为 2 6 ,1 8,1 3,1 2m。根据位移量限定法 ,两个活动段落的古地震活动历史是完整的

| Abstract: | The Sertengshan piedmont fault is a very important active fault. Along with the Langshan piedmont fault, it controls the northwest boundary of the Hetao fault depression zone. We have carried out detailed investigation of fault activity and paleoseismology on east of Delingshan segment of this fault, on which little work has been done before. The result of investigation indicates that the geomorphic characteristics of late Quaternary activity on this segment of the Sertengshan piedmont fault are very remar |
