Meso-Cenozoic growth of the eastern Qilian Shan, northeastern Tibetan Plateau margin: Insight from borehole apatite fission-track thermochronology in the Xiji Basin

Paleogene–Neogene environmental evolution and the uplift‐sedimentation response of the NE Tibetan Plateau

“…This demonstrates that Liupan Mountain was still at a lower altitude before 8 Ma. (2) In the late Miocene, the uplift of the Liupan Mountain reached 1 000 meters (Figure 7; Li et al, 2014; Peng et al, 2022; Shi et al, 2006; Wang et al, 2014). The rapid exhumation events of the middle‐late Miocene widely developed on the north‐eastern margin of the Tibetan Plateau, as well as the changes in sedimentary facies, provenance, and climate of the basins (Qaidam Basin, Ningnan Basin, Hexi Corridor Basin, Lanzhou Basin).…”

“…Since the Miocene, the Longxi Block on the western side of the Liupan Mountain began to rise (e.g., Kou et al, 2021; Peng et al, 2022; Song et al, 2001; Shi et al, 2006; Wang et al, 2014; Zheng et al, 2005), and the Tibetan Plateau started to affect the Liupan Mountain. The main supporting evidence is as follows: (1) In the Longde section on the western margin of the Liupan Mountain, the Qingshuiying and Zhang'enbao formations are in unconformable contact.…”

“…Sketch map of the range of the north‐eastern margin of the Tibetan Plateau uplift since 23 Ma. The elevation data originate from Meng et al (2020), Peng et al (2022), Wang et al (2020), Zheng et al (2005), and Zhuang et al (2018). [Colour figure can be viewed at wileyonlinelibrary.com]…”

“…(2) In the late Miocene, the uplift of the Liupan Mountain reached 1 000 meters (Figure 7; Li et al, 2014;Peng et al, 2022;Shi et al, 2006;Wang et al, 2014).…”

“…Digital elevation model of the north‐eastern Tibetan Plateau (modified from Fan et al, 2007; Yan et al, 2006). The coloured square denotes the distribution of bedrock AFT; these data come from Wang et al (2014, 2021), Li et al (2020), He et al (2021), Peng et al (2022), Zheng et al (2005), and the references therein. The age of the fault is taken from Dupont et al (2008), Li et al (2020), Song et al (2020), Shi et al (2015), Zheng et al (2005), Wang et al (2011, 2014), and Yang et al (2019).…”
