“…There have also been some sedimentary provenance studies in the Tajik Basin, including the Peshtova, Dashtijum and Asku sections, from northeast to southwest, respectively (Figure 4 and Figure 8) (Chapman et al, 2019;Wang et al, 2019;Sun et al, 2020). In the Peshtova section, the youngest zircon U/Pb age peak at ∼45 Ma first appears in sediment with depositional ages of ∼35 Ma (Wang et al, 2019). In the Dashtijum section, the zircon U/Pb age peak at ∼45 Ma occurred in samples with depositional ages between the Late Cretaceous (sample DSH-1430 in the Sangoba Formation) and the Oligocene (sample DSH-2225 in the Baldshuan Formation).…”

“…The Pamir Plateau is an important part of the Western Himalayan Syntaxis in the NW Tibetan Plateau (Figure 1A). Numerous studies have focused on understanding the tectonic activities of this region (Cowgill, 2009;Sobel et al, 2013;Wei et al, 2013;Yang et al, 2014;Kufner et al, 2016;Liu et al, 2017;Rutte et al, 2017;Chen et al, 2018;Li et al, 2020), the Paratethys Ocean retreat (Bosboom et al, 2014;Wang et al, 2014;Carrapa et al, 2015;Sun et al, 2016a;Bosboom et al, 2017;Kaya et al, 2019;Wang et al, 2019;Sun et al, 2020) and coincident aridification across Central Asia (Zhang et al, 2007a;Zhang et al, 2007b;Huber and Goldner, 2012;Caves et al, 2014;Licht et al, 2014). The Pamir Plateau and the SW Tian Shan Mountains formed a geographic barrier that blocks the transport of moisture by the westerlies, leading to stepwise aridification across Central Asia and formation of the Taklimakan Desert (Sun and Liu, 2006;Zheng et al, 2015a).…”

“…Previous studies suggest a stepwise exhumation or uplift history of the Pamir, as follows. 1) Late Paleocene to Oligocene initial activities (Cheng et al, 2011;Carrapa et al, 2015;Sun et al, 2016b;Sun et al, 2020); 2) Late Oligocene accelerating uplift (Blayney et al, 2016;Blayney et al, 2019;Wang et al, 2019); 3) Mid-Miocene to Late Miocene rapid uplift that has continued to the present day (Sobel and Dumitru, 1997;Blayney et al, 2019). However, the timing and magnitude of each episodic uplift are debatable.…”

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.

“…The proto‐Paratethys sea incursions occurred during the Cretaceous and Paleogene until its drastic retreat during the late Eocene, followed by its isolation as the Paratethys during the Oligocene and Miocene (e.g., Kaya et al, 2019; Naidin et al, 1980; Popov et al, 2004). The fluctuations of this sea across Eurasia have not only shaped Asian paleoenvironments but also provide a valuable record of Asian tectonism and eustatism (e.g., Bosboom et al, 2017, 2014; Carrapa et al, 2015; Hendrix et al, 1992; Kaya et al, 2019; Ramstein et al, 1997; Sun et al, 2016; Wang et al, 2019). We focus here on the onset and early history of these fluctuations during the Cretaceous and Early Paleogene because the timing and drivers of the sea incursions into Central Asia still remain unclear.…”

Cretaceous Evolution of the Central Asian Proto‐Paratethys Sea: Tectonic, Eustatic, and Climatic Controls

et al. 2020

The timing and mechanisms of the Cretaceous sea incursions into Central Asia are still poorly constrained. We provide a new chronostratigraphic framework based on biostratigraphy and magnetostratigraphy together with detailed paleoenvironmental analyses of Cretaceous records of the proto-Paratethys Sea fluctuations in the Tajik and Tarim basins. The Early Cretaceous marine incursion in the western Tajik Basin was followed by major marine incursions during the Cenomanian (ca. 100 Ma) and Santonian (ca. 86 Ma) that reached far into the eastern Tajik and Tarim basins. These marine incursions were separated by a Turonian-Coniacian (ca. 92-86 Ma) regression. Basin-wide tectonic subsidence analyses imply that the Early Cretaceous sea incursion into the Tajik Basin was related to increased Pamir tectonism. We find that thrusting along the northern edge of the Pamir at ca. 130-90 Ma resulted in increased subsidence in a retro-arc basin setting. This tectonic event and coeval eustatic highstand resulted in the maximum observed geographic extent of the sea during the Cenomanian (ca. 100 Ma). The following Turonian-Coniacian (ca. 92-86 Ma) major regression, driven by eustasy, coincides with a sharp slowdown in tectonic subsidence during the late orogenic unloading period with limited thrusting. The Santonian (ca. 86 Ma) major sea incursion was likely controlled by eustasy as evidenced by the coeval fluctuations in the west Siberian Basin. An early Maastrichtian cooling (ca. 71-70 Ma), potentially connected to global Late Cretaceous trends, is inferred from the replacement of mollusk-rich limestones by bryozoan-and echinoderm-rich limestones.
