“…60–50 Ma static peak of detrital AFT ages was also discovered in the Neogene HTTL section in the northeastern Qaidam Basin (He et al., 2018), in the Cenozoic sediments of the Jiuquan Basin north of the Qilian Shan (He et al., 2017) and the Subei Basin northwest of the Qilian Shan (He et al., 2020), suggesting that late Paleocene‐early Eocene rock exhumation occurred extensively in the Qilian Shan. This interpretation is in accordance with the early Eocene rapid cooling of bedrock in the Qilian Shan revealed by in situ AFT and 40 Ar/ 39 Ar ages (Li, Zuza, et al, 2020; Qi et al., 2016; Zhuang et al., 2018). The sedimentation patterns responded to this tectonic deformation event: proximal accumulation of coarse detritus and thrust‐related growth strata (progressive unconformity) developed in the Lulehe Fm.…”

The evolution of the tectonic deformation of the northeastern Tibetan Plateau (TP) in the Cenozoic is significant for understanding plateau growth during India-Asia convergence. However, when deformation began and how it has developed in this pivotal region remain controversial. We focus on the temporal progress of Cenozoic deformation in the Qilian Shan, a major tectonic belt of the northeastern TP. In the present study, detrital apatite fission-track (AFT) thermochronological analysis was performed on Oligocene-Quaternary synorogenic sediments in the northern Qaidam Basin, where detritus is sourced from the Qilian Shan. Age components of buried but unannealed detrital AFT samples reveal two static peaks (i.e., peak ages that are consistent upsection) at ca. 60-50 Ma and ca. 40-36 Ma and a moving peak (i.e., peak ages that are younger upsection) with increased lag time during ca. 30-8 Ma. These new detrital AFT ages, integrated with the analysis of sedimentary provenance and data from previously published studies, indicate that Cenozoic tectonic deformation began in the Qilian Shan in the late Paleocene-early Eocene. Furthermore, the Qilian Shan experienced a subsequent episodic deformation event in the late Eocene and the deformation or erosion of some terranes in the Qilian Shan decelerated during the Oligocene-Miocene. Our results suggest that the northeastern TP responded to the India-Asia collision almost instantaneously.

“…Last, the complex polyphase arc-collisional history in this region probably focused Cenozoic shortening and strike-slip faulting related to the India-Asia collision. This region occupies the northernmost margin of the Tibetan Plateau, and available thermochronology constraints suggest that exhumation and deformation here started shortly after initial India-Asia collision (i.e., Eocene; e.g., An et al, 2020;Dupont-Nivet et al, 2004;B. Li et al, 2020b;Qi et al, 2016).…”

Asian and the Tethyan oceanic domains are separated by the Tarim and North China cratons whose geologic histories are critical for deciphering the interactions of the two orogenic systems to the north and south. A major obstacle for establishing the geologic history of Tarim and North China cratons is that the two tectonic entities are currently bounded by Cenozoic structures along the southern margin of the Tian Shan and the northern margin of the Tibetan plateau (Figure 1). These structures have either reactivated or strongly modified the earlier tectonic configurations of the region (e.g., Yin & Nie, 1996). For example, Cenozoic structures that bound the southern margin of Tarim and North China cratons overprinted Mesozoic extensional basins (X.

Geomorphic expression of the Lenglong Ling area, eastern Qilian Shan, and its coupling relationship with the deep structures

Located at the outer edge of the northeastern Tibetan Plateau, the Qilian Shan has long been considered to be the key area to address the issue of how the Tibetan Plateau generates its high topography. However, in spite of the fruitful achievements on the growth pattern and subtle crustal structures of the Qilian Shan, what we know about the regional topography evolution and its relationship with the deep structures are still lacking. In this study, the landscape features of the eastern Qilian Shan and the probable drainage evolution history of the Lenglong Ling, located within the central part of the eastern Qilian Shan, are investigated, based on the multiple geomorphic analyses (i.e., HI and steepness distributions, and the Gilbert and χ metrics). The topographic results show that high HI and steepness values distribute mainly in areas controlled by active faults (i.e., the mountain areas). In addition, the Gilbert and χ metrics suggest that the main Lenglong Ling divide is stable. According to the drainage divide stability criteria, we suggest that the presence of the uplift rate gradient in the eastern Qilian Shan (i.e., with higher uplift in the Lenglong Ling area), which is suggested by the topographic results, has driven the main divide to migrate southward and is now “holding” the divide in place. Taking the previously published magnetotelluric imaging into account, we reveal the coupling relationship between the deep structures and the regional geomorphic features, and further suggest that the Lenglong Ling Fault, or the Qilian‐Haiyuan Fault, makes a difference in regional strain transferring and relief generation.
