“…The sedimentary sequence, tectonic evolution, and palaeomagnetic analysis proposes that the NE–SW direction of crustal shortening and related range uplift had not commenced until the Miocene (An et al, 2018; Bovet et al, 2009; Fan et al, 2019; Lin, Chen, Wyrwoll, & Cheng, 2010; Liu, Hu, Shi, Chen, & Yan, 2020; Liu et al, 2019; Liu, Wang, Zhang, Pang, & Yu, 2016; Lu & Xiong, 2009; Shi et al, 2015; Shi, Dong, & Hu, 2019; Wang et al, 2011, 2013; Wang, Zhang, Pang, et al, 2016; Wang, Zhang, Yu, et al, 2016; Wang, Zheng, et al, 2017).

The Late Cenozoic crustal shortening in the north‐east margin of the Qilian Shan: Evidence from the Fengle Basin, Gansu Province

The northeast margin of the Qilian Shan forms the front of the northeastward expansion of the Tibetan Plateau. Its Cenozoic crustal shortening is significant for understanding the uplift and growth of the Tibetan Plateau. The Fengle Basin, in the northeast margin of the Qilian Shan, is characteristic of the typical regional superimposed deformation in Cenozoic strata, documenting the Cenozoic tectonic evolution process in the northeast margin of the Tibetan Plateau. In this study, we conducted large-scale geological mapping and regional structural analysis in the Fengle Basin, and rebuilt the two phases of Late Cenozoic crustal shortening deformation in this area: (a) The NW-SE shortening deformation in the Middle-Late Miocene led to the formation of NE-striking folds in the Fengle Basin, and a hiatus between the Lower and Upper formations of the Gansu Group, probably linked with the far-field effect of the northwestward subduction of the Pacific Plate. (b) The NE-SW shortening in the Late Miocene-Early Pleistocene overprinted the early NE-striking folds, resulting in the development of a large-scale dome structure in this area. The NE-SW shortening is associated mainly with the northeastward growth of the Tibetan Plateau. This study provides crucial evidence for the reconstruction of the intracontinental deformation process in the northeastern periphery of the Tibetan Plateau.

Signals of uplift and deformation across the Tibetan Plateau associated with the Cenozoic India-Asia collision can be used to test debated deformation mechanism(s) and the growth history of the plateau. The spatio-temporal evolution of the Eastern Kunlun Range in northern Tibet provides a window for understanding the intracontinental tectonic evolution of the region. The Eastern Kunlun Range exposes the Cenozoic Kunlun left-slip fault and kinematically linked thrust belts. In this contribution, integrated field observations and apatite fission-track thermochronology were conducted to constrain the initiation ages of localized thrust faults and the exhumation history of the Eastern Kunlun Range. Our analyses reveal four stages of cooling of the Eastern Kunlun Range. We relate these four stages to the following interpreted tectonic evolution: (1) an initial period of early Cretaceous cooling and slow exhumation over the early Cenozoic, which is associated with the formation of a regional unconformity observed between Cretaceous strata and early Cenozoic sediments; (2) rapid Oligocene cooling that occurred at the eastern domain of the Eastern Kunlun Range related to the southern Qaidam thrusts; (3) extensive rapid cooling since the early-middle Miocene in most of the eastern-central domains and significant uplift of the entire range; and (4) a final pulse of rapid late Miocene-to-present cooling associated with the initiation of the Kunlun left-slip fault and dip-slip shortening at the western and eastern termination of the left-slip fault. Early Cenozoic deformation was distributed along the northern extent of the Tibetan Plateau, and overprinting out-of-sequence deformation migrated back to the south with the initiation of Miocene-to-present deformation in the Eastern Kunlun Range.

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.
