Abstract:

Since the Middle to Late Miocene, the tectonic regime of eastern North China has undergone a significant transition from extensional deformation to a shear-dominated system under a nearly E-W compressional stress field. This shift is attributed to the combined influence of the eastward extrusion of the Tibetan plateau and the retreat of the West Pacific Plate. The Tanlu fault zone, a major active strike-slip structure in eastern China, serves as the tectonic boundary between the Luxi and Ludong blocks. Within the Luxi Uplift, located in the east part of the North China Craton, a prominent basin-and-range system has developed, controlled by a series of NW-trending faults. Late Quaternary activity along these faults, including the Cangni Fault, Xintai-Mengyin Fault, Tongyedian-Sunzu Fault, Zhangdian-Renhe Fault, Yidu Fault, and Shuangshan-Lijiazhuang Fault, demonstrates a parallel, roughly equidistant arrangement, with a convergent pattern toward the Tanlu fault zone.

The Shangwujing Fault is a crucial NE-trending dextral strike-slip fault, and the Shuangshan-Lijiazhuang Fault is a NW-trending sinistral strike-slip fault. Spatially, these two faults form an X-shaped conjugate structure, which governs the formation and evolution of the Linqu Basin. The shallow surface expression of the Shangwujing Fault can be segmented into northern, central-northern, central-southern, and southern sections, demarcated by Tongyugou Village, Dongliushui Village, and Yiyuan Beibudong Village. While prior studies identified Late Pleistocene activity in the central-northern segment, evidence for fault motion between Jiujie Village and Dongliushui Village remained insufficient.

Key words: Luxi block, Shangwujing Fault, Airborne Light Detection and Ranging (LiDAR), right-lateral strike-slip, late Pleistocene activity

摘要:

上五井断裂是鲁西地块内一条重要的NE向晚第四纪活动断裂, 与双山-李家庄断裂共同构成了“X”形共轭构造。在地表浅层, 上五井断裂从北向南以桐峪沟村、 东流水村、 沂源北埠东村为界, 大致可以划分为北段、 中北段、 中南段和南段。文中采用地质地貌调查、 机载激光雷达航测、 断层泥定年等方法, 重点对上五井断裂中北段九杰村—东流水村之间的段落进行了位移测量和活动性研究, 发现了该段落的新活动证据。结果表明, 九杰村—东流水村之间的断裂长约18km, 右旋走滑活动显著。九杰村南山脊的右旋位移量为475~580m, 崔木村东山脊的右旋位移量为48~74m, 东流水村附近冲沟的最小右旋位移量为35m。根据地貌位错和断层泥电子自旋共振定年结果((94±5)kaBP), 确定该段落晚更新世有活动。基于文中研究, 确定上五井断裂中北段晚第四纪活动段长约45km。历史上, 上五井断裂与双山-李家庄断裂的交会处曾发生1829年 6¼ 级地震, 综合分析认为上五井断裂的潜在发震能力可达6.5级。
