“…Most previous studies suggest that the formation age of the Three Gorges is 1.2 –0.7 Ma (Pleistocene) based on studies of terraces in the Three Gorges, Quaternary deposits in the Jianghan Basin, and continuous cores of boreholes in the Yangtze delta (Tang and Tao, 1997; Li et al, 2001; Yang et al, 2006; Wang et al, 2009; Xiang et al, 2011, 2018; Liu et al, 2018; Sun et al, 2018). Other studies, however, have indicated that the Three Gorges formed before the Pliocene, based on the fluvial deposition in the lower reaches of the Yangtze River, detrital zircons in the Yangtze delta, Nd and Pb isotopes in the sediments of the Hanoi Basin, and the Cenozoic sediments in the Jianghan Basin and offshore basins in East China (Clift et al, 2008; Jia et al, 2010; Zheng et al, 2013; Yang et al, 2019; Fu et al, 2021; Sun et al, 2021; Zhang et al, 2021). Despite disagreement surrounding the formation time of the Three Gorges, previous studies have indicated that the opening of the Three Gorges was an important capture event that led to the birth of the modern Yangtze River (Yang et al, 2006; Wang et al, 2009; Jia et al, 2010; Liu et al, 2018; Sun et al, 2018).…”
