“…In the Eastern Tian Shan, the Bogda Range and the Harlik Mountain show different ages of initial uplift. The onset time of the Bogda Range uplift was probably in the early Jurassic or Triassic (Chen et al, 2015; Fang, Wu, Wang, Hou, & Guo, 2019; Zhao et al, 2019), whilst the uplift of the Harlik Mountain initiated in the Late Permian (Zhao et al, 2019). After a long‐term evolution in the Early Mesozoic, the initial shape of the basin and range in the Eastern Tian Shan area formed in the Late Jurassic (Fang et al, 2019; Yang et al, 2015).…”

Tectono‐geomorphic evolution of Harlik Mountain in the Eastern Tian Shan, insight from thermochronological data and geomorphic analysis

The Harlik Mountain is in the easternmost part of the Tian Shan and is a prime example of an intracontinental orogenic belt. Several studies have used low‐temperature thermochronology to understand the uplift history of this range. However, complicated structures have a profound impact on the study of the tectonic evolution of the Harlik Mountain during the Mesozoic‐Cenozoic. Here, we refine the structural characteristics of the Harlik Mountain and then acquire the detailed thermal histories in different parts of the range. Through field observations, we demonstrate that the brittle Harlik Fault experienced two activities, including early normal faulting and late right‐lateral strike‐slip normal faulting. In particular, geomorphic and river analyses indicate that the topography of the Harlik Mountain was significantly influenced by faults. Combined with the thermochronological data from previous studies, thermal history modelling based on our new data on the Harlik Mountain suggest three fast cooling phases in the 128–110 Ma, 70–55 Ma, and 50–35 Ma. The first and the third cooling phases were associated with fault activities and the second cooling phase was related to regional denudation. The first phase of faulting, in the late Early Cretaceous, may be caused by stress relaxation after the Cimmerian collision. The second phase of faulting was likely to relate to local stress adjustment from the India‐Eurasia collision during the Eocene to Oligocene. Moreover, Late Cretaceous to Palaeocene regional cooling was probably affected by the collision of the Karakoram Block with Eurasia.

“…This phase of rapid exhumation is also recorded by AFT data and thermal history modeling from the Bogda mountain east of Urumqi (e.g., [67,70]). Along the Du-Ku highway, numerous thermochronological data have been achieved with most dating ages ranging from the late Mesozoic to the late Miocene [14,18,43,48]. The late Oligocene-early Miocene is revealed by thermal history modeling of a single bedrock sample south of the Haxilegen Pass [14,43,48].…”

The present topography of Tian Shan is related to the India-Asia collision, whereas the mechanisms for the topographic growth of Tian Shan remain at the center of debate partly due to the poorly constrained onset timing of the Cenozoic tectonic deformation. Our new apatite (U-Th)/He (AHe) data in the northern Chinese Tian Shan suggest that rapid cooling commenced at 20.2±4.9 Ma along the northern margin, which is consistent with published fission-track data from the same area and confirms that the youngest component of fission-track has been totally annealed. Moreover, AHe data from the interior mountain suggest that enhanced cooling began at 28.0±2.3 Ma, which is slightly older than that from the northern edge of the mountain. Although thermochronological data suggest that both the interior and northern margin of the northern Chinese Tian Shan have undergone rapid cooling since the late Oligocene-early Miocene, well preservation of relict low-relief surfaces along the northern rim of the northern Chinese Tian Shan and published thermochronological data indicate that the northern Chinese Tian Shan may have experienced differential exhumation in the Cenozoic. Combining the thermochronological and geomorphological evidence, we propose a progressive northward growth model for the northern Chinese Tian Shan. During the late Oligocene and early Miocene, compressive deformation derived from the India-Asia collision have arrived at the northern Tian Shan to reactivate both the interior mountain and its northern margin, while intense exhumation was concentrated in the interior mountain range. Then, deformation extended northward into the foreland basin that may be initiated in the middle-late Miocene.
