“…The time of collision between the Yili-Central Tianshan block and the Tarim craton ranged from Late Devonian to Middle Triassic (e.g., Xia et al, 2008;Han et al, 2011;Zhang et al, 2007). The model showing that final collision along the South Tianshan region terminated in the Late Devonian-early Carboniferous is mainly based on the regional unconformity at the base of the Dahalajunshan Formation (Xia et al, 2008(Xia et al, , 2012Charvet et al, 2011;X.Y.…”

“…Final closure of the South Tianshan Ocean has been proposed to mark the termination of the paleo-Asian Ocean in the southwestern corner of the Central Asian orogenic belt Xiao et al, 2009Xiao et al, , 2013. However, the proposed timing of the collision between the Tarim craton to the south and the Yili-Central Tianshan block is controversial, varying from Late Devonian to Middle Triassic (Zhang et al, 2007;Xia et al, 2008;Gao et al, 2011;Y.G.

“…A late Carboniferous collision has been supported by recent age data from postcollision granites (300-270 Ma; Biske and Seltmann, 2010;Gao et al, 2011;Han et al, 2011) and high-to ultrahighpressure ([U]HP) metamorphic rocks (320-310 Ma;Hegner et al, 2010;Su et al, 2010;Klemd et al, 2011; in the South Tianshan orogenic belt. However, some researchers place the major collisional event in the Late Permian to Middle Triassic, based on the ages of two Late Permian radiolarian specimens from ophiolitic mélange (Li et al, 2005) and Triassic zircon U-Pb ages from eclogites (Zhang et al, 2007). Meanwhile, it has also been suggested that the collision along the South Tianshan region terminated in the Late Devonian-early Carboniferous based on a regional unconformity (Xia et al, 2008(Xia et al, , 2012Charvet et al, 2011;X.Y.…”

Provenance of late Paleozoic strata in the Yili Basin: Implications for tectonic evolution of the South Tianshan orogenic belt

The Yili Basin in NW China preserves a late Paleozoic volcano-sedimentary succession, the provenance of which helps to constrain the tectonic evolution of the South Tianshan orogenic belt. U-Pb ages and trace-element and Hf isotopic compositions of detrital zircons from the Late Devonian to earliest early Carboniferous strata in the Yili Basin suggest that the unit contains detritus mainly derived from basement rocks and contemporaneous arc-related volcanic rocks.

“…However, despite abundant evidence that complex polyphase zircons with clear core-rim age differences are formed in a variety of geological settings (e.g., Carter and Moss, 1999;Whitehouse and Platt, 2003;Wu and Zheng, 2004;Wan et al, 2006;Zhang et al, 2007) and are thus commonly observed in the sedimentary record, there is no consensus on how such grains should be treated during U-Pb detrital provenance analysis. During the discussion sessions at the 3rd meeting of the Working Group on Sediment Generation on which this special volume is based, there was also no consensus between different geochronology laboratories on target spot location for detrital zircon grains.…”

Available online xxxx U-Pb detrital zircon geochronology is a powerful and well-established tool in provenance studies. Modern analytical techniques (particularly LA-ICPMS) increasingly facilitate the rapid acquisition of large datasets. While improvements in data handling approaches have been explored in detail (e.g., more robust propagation of analytical uncertainties and inter-laboratory age reproducibility studies), there currently are no commonly established protocols for target spot location on polyphase detrital zircon grains: should the analyst ablate the zircon core, rim, or both? Here, we present two regional U-Pb detrital zircon datasets, one from the Banda Arc in Eastern Indonesia and one from the European Alps pro-foreland basin. We demonstrate that preferential ablation solely of cores or rim overgrowths results in a failure to detect age peaks, and also that generation of single-grain core-rim age pairs can permit additional characterisation of the source rock. Thus, both cores and rims should be analysed where possible, to maximise the data obtained from detrital zircon. In addition, we advocate the use of the single-analysis concordia age in visualizing and presenting U-Pb data, which is currently under-utilised in detrital provenance studies. We utilise a large (ca. 49,500 analyses) detrital zircon dataset to demonstrate that the single-analysis concordia age maximises precision throughout geological time (which removes the need to present ages derived from different isotopic ratios across an arbitrary age threshold), and obviates the necessity to separately assess discordance.

“…Some authors argued that continent amalgamation was accomplished in the preCarboniferous and that a post-collisional continental rifting occurred during the Carboniferous to Permian (Che et al 1996;Xia et al 2004b). Others suggest that the collision in southwestern Tianshan occurred as late as Late Permian-Triassic (Li et al 2002(Li et al , 2005Zhang et al 2007). …”

Continuous magmatic activity occurred in the western Chinese Tianshan, Central Asia, from the Carboniferous to the Permian, i.e. before and after the Late Carboniferous amalgamation of Junggar and the Yili Blocks. Zircon U-Pb LA-ICPMS and Ar-Ar data reveal a coincidence in time between regional wrench faulting and granitoid emplacement. Permian post-collisional granitoids crop out within or at the margins of large-scale dextral strike-slip shear zones, some of them show synkinematic fabrics. The whole rock geochemical features of the Early-Middle Permian granitoids indicate an evolution from high-K calc-alkaline towards alkaline series. In other places of the North Tianshan, alkaline magmatism occurred together with deep marine sedimentation within elongated troughs controlled by wrench faults. Therefore, in contrast with previous interpretations that forwarded continental rift or mantle plume hypotheses, the coexistence of diverse magmatic sources during the same tectonic episode suggests that post-collisional lithosphere-scale transcurrent shearing tightly controlled the magmatic activity during the transition from convergent margin to intraplate anorogenic processes.
