“…According to the true thickness (between KLY-3 and KLY-1) and average sedimentary deposition rates (for the bottom segment of the magnetostratigraphic profile), KLY-1 is estimated to have been deposited at ∼56 Ma (Figure 3 and Figure 4). However, the lithology of KLY-1 is consistent with Upper Cretaceous gravelbearing coarse sandstone strata in the SW Tarim Basin (Si et al, 2007;Sun et al, 2016b;Chen et al, 2018;Li et al, 2021), and the uncorrected magnetostratigraphic age may be affected by inaccuracies in the sedimentation rate or sedimentary discontinuities. On the other hand, detrital zircon U/Pb ages of KLY-3 and KLY-7 yielded the youngest single zircon ages of 43.7 Ma (n 1) and 23.1 Ma (n 1).…”

The Pamir Plateau region of the Northwestern Tibetan Plateau forms a prominent tectonic salient, separating the Tajik and Tarim basins. However, the topographic evolution of the Pamir Plateau remains elusive, despite the key role of this region played in the retreat of the Paratethys Ocean and in aridification across Central Asia. Therefore, the SW Tarim and Tajik basins are prime locations to decipher the geological history of the Pamir Plateau. Here, we present detrital zircon U/Pb and apatite fission-track (DAFT) ages from the Keliyang section of the SW Tarim Basin. DAFT ages show that sediments had three components during the Late Cretaceous and two components since the Oligocene. Detrital zircon U/Pb ages mainly cluster between 400 and 500 Ma during the Late Cretaceous, and coincide with ages of the Songpan-Ganzi and the West Kunlun Mountains. In contrast, detrital zircon U/Pb ages in the Eocene sediments are centered at around 200–300 Ma and 40–70 Ma, with a peak at ∼45 Ma, consistent with data from the Central Pamir and the West Kunlun Mountains. The ∼45 Ma peak in detrital zircon U/Pb ages since the Eocene indicates a new sedimentary source from the Central Pamir. Non-metric multi-dimensional scaling (MDS) analyses also show that the sedimentary source was closer to the Central Pamir after the Eocene, when compared to the Late Cretaceous. The result shows a clear Eocene provenance change in the Keliyang area. Moreover, this Eocene provenance shift has been detected in previous studies, in both the Tajik and Tarim basins, suggesting that the entire Central Pamir region likely experienced quasi-simultaneous abrupt uplift and paleo-geomorphological changes during the Eocene.

“…Balanced cross sections indicate that a large part of the total shortening across this range was accommodated by thin‐skinned tectonics within its foothills, with structures propagating into the southwestern Tarim Basin (Laborde et al., 2019 and references therein) (Figures 1c and 1d). Despite a growing number of studies documenting the deep structure of this outer part of the WKR from seismic profiles (e.g., Cheng et al., 2017; Jiang et al., 2013; Li et al., 2021; Lu et al., 2016; Sun et al., 2019; Wang et al., 2016, 2021) quantitative constraints are still missing to document the long‐term temporal evolution of deformation in this region.…”

Kinematics of Cenozoic Shortening of the Hotan Anticline Along the Northwestern Margin of the Tibetan Plateau (Western Kunlun, China)

et al. 2022

Kinematic constraints on the Cenozoic deformation along the northwestern edge of the Tibetan Plateau remain limited. Combining surface geological data and seismic profiles, we document the structural geometry and kinematics of the large‐scale east‐west striking Hotan anticline, along the foothills of the Western Kunlun Range. Four new balanced cross sections are constructed, and the temporal evolution of deformation is deciphered from the exceptionally well‐imaged growth strata at the front of the fold. This anticline results from a broad fault‐bend fold, subsequently deformed by a footwall duplex. The total shortening across the whole structure is relatively constant along strike, from ∼40 to ∼35 km. However, the shortening accommodated by the duplex varies laterally from ∼50–40% to 0% of the total shortening. Two distinct successive patterns of growth strata are recognized and are interpreted to be representative of deformation on the ramp anticline, followed by deformation on the duplex. The onset of deformation initiated by ∼16 Ma. Deformation of the underlying duplex began at ∼12 Ma to the west and subsequently propagated eastward. From these results, we determine a shortening rate of ∼5 mm/yr from ∼16 to ∼8–9 Ma across the Hotan thrust system, followed by a significant decrease in shortening rate, possibly down to <0.5 mm/yr. We explore the significance of this deceleration of deformation at the scale of the Western Kunlun foothills and at a broader regional scale as it may point to a regional kinematic reorganization by the late Miocene.
