“…The ESR ages of the sediments on the Yunmeng planation surface and terrace T 5 are ca. 0.75 Ma and 0.73-0.7 Ma, respectively (Xiang et al, 2005(Xiang et al, , 2020, so we believe that the paleo-Chuan River flowed westward before 0.75 Ma and reversed to flow eastward between 0.75 Ma and 0.73 Ma (Fig. 11a and b).…”

“…Most of the high-elevation landforms related to the plateau were distributed east of the main Himalayan collision zone, where the crustal volume increased more than 2 × 10 7 km 3 in Cenozoic times (Clark et al, 2005). The crustal deformation and thickening in the southeastern Tibetan Plateau had a significant effect on large fluvial systems, landforms, and climate in East Asia (Brookfield, 1998;Zhong et al, 2018;McRivette et al, 2019;Li et al, 2020;Xiang et al, 2020;Li et al, 2022). Thus, research of river evolution can reveal the processes and degree of effect of the Tibetan Plateau tectonic activity on East Asia and its surrounding regions, and help us better understand the significance of the Tibetan Plateau uplift.…”

In the Three Gorges and adjacent areas, there are three planation surfaces and five terraces along the Yangtze River that record the evolution history of the river system. Here, we used diagnostic heavy minerals, U-Pb geochronology, and trace elements of detrital zircons from one planation surface, two terraces, and a modern point bar to reconstruct the evolution history of the upper Yangtze River, specifically the Chuan River in the Sichuan Basin. The sediments in the lowest planation surface had different felsic source rocks derived from east of the Three Gorges, which indicated that before the disintegration of the lowest planation surface (0.75 Ma), there were two paleorivers: the westward-flowing paleo-Chuan River and eastward-flowing paleo-Yangtze River separated by the Huangling Dome. At 0.75–0.73 Ma, the dominant detrital zircons from the Sichuan Basin in the sediments of terrace T5 (the highest terrace) confirmed that the paleo-Yangtze River cut through the Three Gorges and captured the paleo-Chuan River, and the Daliang Mountains became the new drainage divide. Finally, the appearance of materials from the upper Jinsha River in terrace T2 indicated that the paleo-Yangtze River progressively captured the paleo-Jinsha River, and the modern upper Yangtze River formed before 0.05 Ma. These river capture events of the upper Yangtze River confirmed the Quaternary uplift of the SE Tibetan Plateau.

“…The region is dominated by a subtropical humid climate nowadays, which is warm in winter and cool in summer. Sedimentological and geochemical studies of the river terrace deposits in the TGR indicate a warm-wet climate during the Early and Middle Pleistocene period and gradually change to a cold-dry environment since the late Middle Pleistocene probably in relation to the uplift of Qinghai-Tibet Plateau (Gonghe Movement), which enhances the plateau monsoon and weaken and block the Indian monsoon (Xiang et al, 2020).…”

The Chronology of Early Human Settlement in Three Gorges Region, China—Contribution of Coupled Electron Spin Resonance and Uranium-Series Dating Method

The Three Gorges region (TGR) located in the geographic center of China, is a transition zone between mountain and plain areas, and a probable migration corridor for hominins and other mammals between South and North China. Detailed chronological information of paleoanthropological evidence in this area could help us better understand the human evolution in East Asia. The OSL and U-series dating methods are two conventional dating methods generally adopted to date such sites; however, their applications were limited by the dating range—restricted to several hundred of millennia and ambiguous stratigraphic relationship between the archaeological remains and the dating target materials. Cosmogenic nuclide burial dating of quartzite stone artifacts and coupled electron spin resonance and uranium series dating (ESR/U-series) of fossil teeth have the potential to date Early–Middle Pleistocene hominin sites in Asia and were applied increasingly in China in recent years. However, the application of cosmogenic 26Al/10Be burial dating is limited in TGR because most sites are dominated by limestone, leading to the scarcity of the quartz component. In this case, the coupled ESR/U-series method plays a more important role in the establishment of the chronology of human settlement. In TGR, by using the coupled ESR/U-series method, we have dated seven important Early and Middle Pleistocene hominin settlement sites, including Longgupo, Jianshi, Yunxian, Meipu, Bailongdong, Changyang, and Yumidong sites. Based on our dating results, we propose that hominins were settled in TGR probably from the early stage of Early Pleistocene (∼2.5−2.2 Ma) at the Longgupo site to the late Middle Pleistocene to Late Pleistocene of the Yumidong site (∼274−14 ka) and very likely to spread to other parts of East Asia during this time period. In view of the potential of coupled ESR/U-series dating on fossil teeth from the hominin sites in the TGR, future work may consider the micro damage or non-destructive analysis of enamel fragment with the ESR method and laser ablation ICP-MS techniques that will make possible the direct dating of precious human fossils in China.

“…The accurate stratigraphic chronological framework provides an appropriate temporal reference system for studying the evolution of the Quaternary sedimentary environment (Gibbard and Hughes, 2021; Xiang et al ., 2020). Quaternary depositional environments were largely influenced by tectonic movements and climate change, with marked differences in temporal and spatial scales (Blockley et al ., 2012; Deng et al ., 2019; Wang et al ., 2021).…”
