“…The lack of Early Paleogene ages from the low‐temperature thermochronology data northern Tian Shan and the occurrence of several meters‐thick Palaeogene calcareous paleosols, in the basins surrounding the range, together imply a semi‐arid climate, low subsidence rate, and no significant tectonic uplift at that time (Jolivet et al., 2018; Yin et al., 2017). Thermochronology studies have indicated that the strong deformation in the Tian Shan piedmont was initiated during the Early Miocene (Hendrix, Dumitru, & Graham, 1994; Sobel et al, 2006), consistent with the timing of provenance change (Chen, Fang, Song, & Meng, 2012; Xiang et al., 2019). During the Late Miocene‐Early Pleistocene, renewed compressive deformation and glaciation erosion in the Tian Shan region were inferred by structural analysis (Charreau et al, 2008; Lu et al., 2010, 2015; Sun, Li, Zhang, & Fu, 2009), 10 Be‐based paleo‐erosion rates (Charreau et al., 2011) and low‐temperature thermochronology (Yin et al., 2017; Yuan et al, 2004).…”

The Chinese Tian Shan is one of the most actively growing orogenic ranges in Central Asia. The Late Miocene‐Quaternary landscape evolution of northern Tian Shan has been significantly driven by the interaction between tectonic deformations and climate change, further modulated by the erosion of the upstream bedrocks and deposition into the downstream basins. In this study, only the accessible Kuitun River drainage basin in northern Tian Shan was considered, and detrital zircon geochronology and heavy minerals were analyzed to investigate the signature of the driving forces for Miocene sedimentation in northern Tian Shan. This study first confirmed a previously recognized tectonic uplift at ca. 7.0 Ma and further revealed that the basin sediments were mainly derived from the present glacier‐covered ridge‐crest regions during 3.3–2.5 Ma. It is suggested Late‐Pliocene to Early Pleistocene sedimentation was likely a response to the onset of the northern hemispheric glaciation. Although complicated, this study highlights that the tectonic‐climatic interaction during the Late Cenozoic orogenesis can be discriminated in the northern Chinese Tian Shan.

“…various Cimmerian blocks (Vincent and Allen, 2001;Xiang et al, 2018). Therefore, evidence indicates that the Chepaizi Uplift and the Sikeshu Depression records a major NE-SW strike compressional regime that took place throughout the Late Jurassic (Fig.…”

Geological mapping, interpreted cross sections, structural analyses and residual thickness maps were used to characterize the evolution of stress setting, structure and stratigraphic distribution of the Chepaizi Uplift, which is a NW-SE trending structure located in the Western Junggar Basin. The NS-trending faults show an important transpressional phase during the Late Permian, as demonstrated by tectonic stress field and stratigraphic thickness variations. A major compressional thrusting and strike-slip phase during the Late Jurassic created a series of NW-SE faults that originated by the large-scale uplift event in the Northern Tianshan. Faults were reactivated as thrust and dextral strike-slip faults. In addition, the angular unconformity observed between Jurassic and Cretaceous provide evidence of this tectonic event. Lots of normal faults indicate that the area records southward tilting and regional derived extensional stress that took place during the Neogene. Before that, thick Early Cenozoic strata are widely deposited. The balanced cross-section highlights the evolution of stress setting and stratigraphic distribution of the Chepaizi Uplift.

“…However, U mass fractions in AFT dating can also be determined by LA-ICP-MS (Hasebe et al 2004) with 44 Ca or 43 Ca typically used as an internal standard element, and 238 U mass fractions either calibrated against NIST SRM 610 or NIST SRM 612 reference material glasses (Soares et al 2014) or using a zeta approach (Cogné et al 2020). FT and U-Pb dating are therefore two of the most useful (and most rapid) techniques in apatite provenance studies, with detrital apatite U-Pb analyses yielding high-temperature cooling ages, whereas detrital AFT data could constrain the timing and degree of cooling related to tectonic uplift and/ or erosion in the source region (Xiang et al 2019).…”

Apatite is a ubiquitous accessory mineral in various rocks (e.g., igneous, metamorphic and clastic sedimentary rocks). However, precise and accurate U-Pb LA-ICP-MS dating of apatite is often compromised by high common Pb levels. Among the different common Pb correction methods, the main advantage of the 204 Pb correction method is that it does not assume U/radiogenic Pb concordance. However, 204 Pb is difficult to measure using ICP-MS instruments because of the isobaric interference of 204 Hg on 204 Pb. We overcome this limitation by using a reaction cell sandwiched between two quadrupoles within an ICP-MS, which can allow the online chemical separation of two different elements. Ammonia reacts efficiently (> 98%) with Hg while isotopes of Pb are not affected. The approach was tested on eight apatite reference materials (McClure Mountain, NW-1, UWA-1, Otter Lake, Slyudyanka, MK-1, Durango and Fish Canyon Tuff) for which there are independent constraints on the U-Pb crystallisation age, by comparing U-Pb dating results employing different reaction gas mixes (NH 3 -N 2 O and NH 3 only) in two laboratories. Based on the U-Pb data and SEM analyses on each sample, we can exclude apatite inter-and intra-grain U-Pb age heterogeneity, except for a c. 4% variability of ages in the Otter Lake sample. Our results show that accuracy and precision for U-Pb dating are not measurably affected by different reaction gases, and we accurately reproduce ages of numerous independently characterised apatites within 4% of the reference ages, and the age reproducibility is typically better than 2%.
