Source-to-sink dynamics in the Kyrgyz Tien Shan from the Jurassic to the Paleogene: Insights from sedimentological and detrital zircon U-Pb analyses

International audienceNew insights in the Mesozoic geodynamic evolution and related basin-range interactions in the Kyrgyz Tien Shan were obtained based on new sedimentological and detrital zircon U-Pb (LA-ICP-MS) results from Jurassic to Paleogene sedimentary sequences. Studied sedimentary sections are located in the Fergana and Yarkand-Fergana basins to the west of the Talas-Fergana Fault (TFF) and in the Issyk-Kul and Ming-Kush-Kökömeren basins to the east. The ages of the Phanerozoic zircon grains found in 18 Jurassic to Paleogene sandstones can be divided into four groups: Caledonian (470–390 Ma), Hercynian (315–260 Ma), Triassic (250–210 Ma) and Jurassic (190–160 Ma) ages. The differences in sedimentation pattern and zircon U-Pb results suggest that the TFF played an important role in the distribution of the sedimentary deposits in the Mesozoic. During the Early - Middle Jurassic, the TFF was active and the strongest subsidence occurred in the Yarkand-Fergana Basin. The provenance of its sediments can be explained both by local sources close to the TFF and by more distal sources to the (south)west, probably stretching into the present-day Pamir. During the Late Jurassic – Early Cretaceous, renewed compression led to the inversion of the Yarkand-Fergana Basin. Around the Jurassic – Cretaceous transition, large alluvial fans developing in a semi-arid to arid climate traceable around the whole Tien Shan were also deposited in the Fergana Basin. A mafic sill intruded within these alluvial fans provides an emplacement age of 144 ± 8 Ma (apatite U-Pb) indicating (sub)volcanic activity during the Early Cretaceous. During the Late Cretaceous to early Paleogene, the area to the west of the TFF experienced marine incursions related to the proto-Paratethys Sea. The dominance of Caledonian ages in the Upper Cretaceous – lower Paleogene detrital samples indicates a change in provenance whereby the drainage areas became larger towards low-relief land area east of the TFF

“…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

et al. 2020

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.
