Structural Style and Latest Activity Analysis of the Southern Segment of the Lanliao Fault

  • 摘要: 兰聊断裂南段构造样式复杂,分段活动特征明显。已有学者针对兰聊断裂的研究,主要集中在范县—东明县一带,而兰聊断裂南段的构造样式与最新活动性研究匮乏。为此采用地震反射剖面与钻孔联合剖面探测方法,对兰聊断裂南段进行较系统地分析,认为兰聊断裂南段构造样式为伸展走滑断裂尾端“马尾扇”结构,其最新活动时代为中更新世中晚期,晚更新世以来未活动,中更新世最大滑动速率为0.061 mm/a,据此判断兰聊断裂南段为中更新世断裂。
