“…The neotectonic evolution has, since a long time, been related to the evolution of the Tibetan Plateau (Peltzer et al, 1985;Tapponnier et al, 1986;Zhang et al, 1998;Sun, 2005;Yin, 2010;. In contrast to the strong deformation of the strata in the western margin of the Ordos Block (Wang et al, 2013;Li et al, 2015;Shi et al, 2015a), only brittle fracturing recorded in the graben owing to the Tibetan Plateau Cen et al, 2015;Shi et al, 2015b;Chen et al, 2015Chen et al, , 2016.

The Late Cenozoic basins in the Weihe–Shanxi Graben, North China Craton are delineated by northeast‐striking faults. The faults have, since a long time, been related to the progressive uplift and northeastward expansion of the Tibetan Plateau. To show the relation between the basins and faults, two Pliocene–Pleistocene stratigraphic sections (Chengqiang and Hongyanangou) in the southern part of the Nihewan Basin at the northernmost parts of the graben are studied herein. Based on the sedimentary sequences and facies, the sections are divided into three evolutionary stages, such as alluvial fan‐eolian red clay, fan delta, and fluvial, with boundaries at ∼2.8 and ∼1.8 Ma. Paleocurrent indicators, the composition of coarse clastics, heavy minerals, and the geochemistry of moderate–fine clastics are used to establish the temporal and spatial variations in the source areas. Based on features from the middle‐northern basin, we infer that the Nihewan Basin comprises an old NE–SW elongate geotectogene and a young NW–SE elongate subgeotectogene. The main geotectogene in the mid‐north is a half‐graben bounded by northeast‐striking and northwest‐dipping normal faults (e.g., Liulengshan Fault). This group of faults was mainly affected by the Pliocene (before ∼2.8–2.6 Ma) NW–SE extension and controlled the deposition of sediments. In contrast, the subgeotectogene in the south was affected by northwest‐striking normal faults (e.g., Huliuhe Fault) that were controlled by the subsequent weak NE–SW extension in the Pleistocene. The remarkable change in the sedimentary facies and provenance since ∼1.8 Ma is possibly a signal of either weak or strong NE–SW extension. This result implies that the main tectonic transition ages of ∼2.8–2.6 Ma and ∼1.8 Ma in the Weihe–Shanxi Graben are affected by the Tibetan Plateau in Pliocene–Pleistocene.

The evolution of the Jinshan Gorge in the middle reaches of the Yellow River in China has long been a topic of debate. Previous studies have primarily focused on the connection between the Sanmen Gorge and Jinshan Gorge, attributing this connection to the Yellow River's carving through the pre‐Cenozoic bedrock areas of the Sanmen Basin. However, the patterns of knickpoint propagation along the river, influenced by tectonic upheaval and base‐level changes, have yet to be explored, despite their potential to understand fluvial system and canyon evolution. In this study, we address this issue by employing forward and inverse numerical modelling of longitudinal profiles of the Jinshan Gorge of the Yellow River and its tributaries and correlating the river terraces in this reach. We investigated 18 terrace profiles to explore their formation processes. The results demonstrated that the steepness index (Ksn) values and the incision rates of tributaries increase downstream, aligning with the relationship between knickpoint elevation and proximity to the Hancheng Fault. The knickpoint propagation appears to be related to the tectonic activities of the Hancheng Fault before 130 ka and then was influenced by climatic change, resulting in the development of five‐stage knickpoints (named Kp1, Kp2, Kp3, Kp4 and Kp5 from old to young) that correlate with the formation of terraces in the downstream area. We calculated the formation ages of Kps 1–4 to be 1.59 ± 0.06, 0.94 ± 0.11, 0.57 ± 0.31 and 0.22 ± 0.14 Ma, respectively. Kps 1, 2 and 4 correspond to the formation of the Yellow River terraces with the ages of 1.24, 1.12 and 0.24 Ma, which were reported previously. The formation of the oldest knickpoint can be correlated to the establishment of the modern course of the Yellow River in this region, which is deduced to be ~1.59 Ma.

Yuncheng Basin, the southernmost basin in the Shanxi Graben System, is considered to be one of the earliest formed in this region. However, due to the insufficient study on the strata and the lack of drilling data, the initial time of the Yuncheng Basin has not been accurately constrained, which heavily restricts our understanding about the formation and evolution of the Shanxi Graben System. In this study, borehole SG-1, which penetrated through the entire Late Cenozoic sediments and reached the basement bedrock, was obtained in the northern part of the Yuncheng Basin, and a detailed magnetostratigraphic study has been carried out on the samples selected from the borehole SG-1. Results show that the borehole SG-1 records 17 normal (N1-N17) and 16 reversed (R1-R16) polarity zones which can correspond to the chron C1n-C4An.1n of the global geomagnetic polarity timescale (GPTS). The bottom of the borehole SG-1 is within chron C4An, and the age of the bottom can be extrapolated to 9.1 Ma according to the sediment accumulation rates calculated by two lowermost major polarity transition boundaries. This age provides precise limitation for the initiation of the Yuncheng Basin and the formation of the Shanxi Graben System. The sediment accumulation rates of the Borehole SG-1 was calculated by major polarity boundaries of chrons and subchrons in the borehole SG-1 and showed significant changes at 9.1, 3.6, and 1.2 Ma. Unlike other basins around the Ordos Block which formed much earlier under the influence of western subduction of the Pacific Ocean, the initiation and evolution of the Shanxi Graben system were mainly controlled by the uplift and outward expansion of the Tibetan Plateau after the Late Miocene. The initiation of the Shanxi Graben System indicates that the far-field effect of the uplift and outward expansion of the Tibetan Plateau reached the central North China Craton by at the latest 9.1 Ma. The effect posed a persistent impact on the evolution of the Yuncheng Basin since 9.1 Ma and led to significant changes of the sediment accumulation rates and sedimentary facies at 9.1, 3.6, and 1.2 Ma in the Yuncheng Basin which correspond well to the prologue of the Qingzang Movement, phase A of the Qingzang Movement, and Kunhuang Movement.
