“…For the Late Neogene (from~15 Ma onwards), renewed cooling associated with denudation and exhumation is suggested by the Novosibirsk massif thermal history model. The Late Neogene episode of rapid cooling is known in the entire CAOB to the south of the WSB (Figure 6) and supported by (1) thermal modeling [36,52,54]; (2) AFT ages of 17-10 Ma [38,62]; and (3) apatite U-Th-He ages of~15-5 Ma [65]. In our study area, geological data recorded (1) the general uplift of the WSB basement in the Early Miocene [30];…”

The West Siberian Basin (WSB) is one of the largest intracratonic Meso-Cenozoic basins in the world. Its evolution has been studied over the recent decades; however, some fundamental questions regarding the tectonic evolution of the WSB remain unresolved or unconfirmed by analytical data. A complete understanding of the evolution of the WSB during the Mesozoic and Cenozoic eras requires insights into the cooling history of the basement rocks as determined by low-temperature thermochronometry. We presented an apatite fission track (AFT) thermochronology study on the exposed parts of the WSB basement in order to distinguish tectonic activation episodes in an absolute timeframe. AFT dating of thirteen basement samples mainly yielded Cretaceous cooling ages and mean track lengths varied between 12.8 and 14.5 μm. Thermal history modeling based on the AFT data demonstrates several Mesozoic and Cenozoic intracontinental tectonic reactivation episodes affected the WSB basement. We interpreted the episodes of tectonic activity accompanied by the WSB basement exhumation as a far-field effect from tectonic processes acting on the southern and eastern boundaries of Eurasia during the Mesozoic–Cenozoic eras.

“…Mid-to Late Cretaceous cooling events have been widely recognized in the Tianshan belt (e.g., Dumitru et al, 2001;Wang et al, 2009b;De Pelsmaeker et al, 2015;Tang et al, 2015;Nachtergaele et al, 2018;Glorie et al, 2019;Rolland et al, 2020), and were generally interpreted as a response to the farfield effects of the Lhasa-Qiangtang collision (120-90 Ma) and/ or Kohistan-Dras Arc collision (90-70 Ma) (Yin and Harrison, 2000;Rolland, 2002;Rehman et al, 2011;Kapp and DeCelles, 2019). A compressional regime in the mid-Cretaceous (120-100 Ma) is documented by coeval tectonic inversion of the Turpan-Hami Basin (e.g., Zhu et al, 2004Zhu et al, , 2006b.…”

“…They are active intracontinental orogenic systems which record the poly-phase exhumation history of Central Asia (e.g., Tapponnier and Molnar, 1979;Yin et al, 1998;Shu et al, 2003;Jolivet, 2017). During the past decades, the reactivation processes of the Tianshan and Junggar have been explored by numerous thermochronological studies (e.g., Hendrix et al, 1994;Dumitru et al, 2001;Wang et al, 2009a, b;Glorie et al, 2010Glorie et al, , 2011Glorie et al, , 2019Jolivet et al, 2010;De Grave et al, 2011, 2012De Pelsmaeker et al, 2015;Jourdon et al, 2018a;Nachtergaele et al, 2018;Yin et al, 2018a;Gillespie et al, 2020), uncovering several distinct periods of exhumation and basement cooling during the Meso-Cenozoic. However, the cooling histories of certain regions turned out to be more complex and protracted, and existing data is still insufficient or contradictory to fully explain the thermo-tectonic evolution of the region.…”

The Eastern Tianshan and East Junggar orogenic belts are major constituents of the southwestern Central Asian Orogenic Belt. This study applies low-temperature thermochronology to constrain the thermotectonic history of these two domains. Apatite fission track (AFT) dating of Paleozoic basement samples from the Eastern Tianshan and East Junggar dominantly yield Cretaceous (126-70 Ma) AFT ages, except for two granitic samples from the East Junggar with older ages of 239 and 157 Ma, respectively. Thermal history modeling reveals that the Eastern Tianshan and southern part of the East Junggar experienced moderate to rapid basement cooling throughout the Cretaceous. We interpret it as a far-field effect of accretion and collision along the south Eurasia margin since the Early Cretaceous. Major faults were reactivated and thus may have played an important role in controlling localized fast uplift and cooling. We also dated seven Mesozoic sandstone samples collected from the eastern margin of the Junggar Basin. The detrital AFT age peaks, together with inverse thermal history modeling of the basement, reveal that the East Junggar underwent late Permian to Early Jurassic cooling episodes. These cooling events are thought to be related to post-orogenic transpression along major faults and distal effect of Qiangtang-Eurasia collision. Combined with already published evidence, our new data suggest that the Eastern Tianshan and East Junggar did not undergo significant exhumation during the Cenozoic.

“…The Central Asian Orogenic Belt (CAOB; Figure 1a), the largest Phanerozoic accretionary orogenic belt in the world (Xiao et al, 2014), is composed of abundant island arcs, accretionary wedges, ophiolites, back‐arc basins, oceanic arcs, and ancient continental blocks (Eizenhöfer & Zhao, 2018; Glorie et al, 2019; Vrublevskii, Nikiforov, Sugorakova, & Kozulina, 2020; Wang et al, 2020; Xiao et al, 2015; Xiao et al, 2020; Zhao et al, 2018; Zheng, Li, Zhang, Xiao, & Li, 2019; Zheng, Zhao, & Yang, 2019).

U–Pb age and Hf isotopic composition of detrital zircons from the modern river of the South Tianshan orogenic belt and their implications for Palaeozoic tectonic and crustal evolution

et al. 2020

View full text Add to dashboard Cite

The U-Pb and Lu-Hf isotopic research of detrital zircons was carried out in southern modern rivers of the South Tianshan (STS) orogenic belt to understand the accretionary processes and crustal evolution in this region. Detrital zircons from river sands yield two dominant age populations at 460-390 Ma and 310-260 Ma with several Precambrian age groups. Such age patterns imply that the significant magmatic events occurred during the Palaeozoic in the STS. Comparative studies on U-Pb age of the detrital zircons from northern and southern river sands in the STS belt provide constraints on the tectonic evolution of the STS belt and its surrounding blocks. Abundant 500-460 Ma detrital zircons in northern river sands probably reflect a bidirectional subduction of the Palaeozoic Central Tianshan Ocean under the Yili Block and the Central Tianshan Block. The 460-390 Ma zircon population in both northern and southern river sands likely implies a bidirectional subduction of the South Tianshan Ocean. A lack of the 380-320 Ma zircon grains in the southern river sands may indicates the northward subduction of the South Tianshan Ocean. A final collision between the Tarim Craton and the southwestern Central Asian Orogenic Belt possibly took place in the Late Carboniferous; the 310-260 Ma zircon population in both northern and southern river sands suggests syn-and post-collisional magmatism. Based on the Hf isotopic signatures in the detrital zircon and magmatic zircons, we propose new constraints on the Palaeozoic crustal evolution of the STS. The continent formation in the STS belt was characterised by reworking of the ancient crust in a compressional environment during the Ordovician (ca. 460-440 Ma). Abundant significant juvenile materials progressively added to the crust through time in an extensional tectonic regime since Late Ordovician to Devonian (ca. 440-390 Ma). The crustal formation is mainly dominated by reworking of the Precambrian basement rocks with limited contribution of juvenile components input into magma formation during Late Carboniferous to Early Permian (ca. 310-260 Ma).
