“…In the Chinese West Junggar, transition from a Carboniferous subductionaccretion setting to a Permian post-accretion setting transpired around 305-300 Ma (Choulet et al, 2012(Choulet et al, , 2013Gao et al, 2014;Geng et al, 2009Geng et al, , 2011Tang et al, 2010;Yin et al, 2013;Zhou et al, 2008). Between~300-250 Ma, alkaline magmatism and A-type granites dominated with minor calc-alkaline and I-type granites in an overall post-collisional setting with major strike-slip deformation and associated extensional-transtensional tectonics (Chen and Jahn, 2004;Choulet et al, 2011Choulet et al, , 2012Choulet et al, , 2013Tang et al, 2010;Zhang et al, 2008;Zhou et al, 2008).

Late-Paleozoic emplacement and Meso-Cenozoic reactivation of the southern Kazakhstan granitoid basement

et al. 2015

International audienceThe Ili-Balkhash Basin in southeastern Kazakhstan is located at the junction of the actively deforming mountain ranges of western Junggar and the Tien Shan, and is therefore part of the southwestern Central Asian Orogenic Belt. The basement of the Ili-Balkhash area consists of an assemblage of mainly Precambrian microcontinental fragments, magmatic arcs and accretionary complexes. Eight magmatic basement samples (granitoids and tuffs) from the Ili-Balkhash area were dated with zircon U-Pb LA-ICP-MS and yield Carboniferous to late Permian (~ 350-260 Ma) crystallization ages. These ages are interpreted as reflecting the transition from subduction to (post-) collisional magmatism, related to the closure of the Junggar-Balkhash Ocean during the Carboniferous – early Permian and hence, to the final late Paleozoic accretion history of the ancestral Central Asian Orogenic Belt. Apatite fission track (AFT) dating of 14 basement samples (gneiss, granitoids and volcanic tuffs) mainly provides Cretaceous cooling ages. Thermal history modeling based on the AFT data reveals that several intracontinental tectonic reactivation episodes affected the studied basement during the late Mesozoic and Cenozoic. Late Mesozoic reactivation and associated basement exhumation is interpreted as distant effects of the Cimmerian collisions at the southern Eurasian margin and possibly of the Mongol-Okhotsk Orogeny in SE Siberia during the Jurassic – Cretaceous. Following tectonic stability during the Palaeogene, inherited basement structures were reactivated during the Neogene (constrained by Miocene AFT ages of ~ 17–10 Ma). This late Cenozoic reactivation is interpreted as the far-field response of the India-Eurasia collision and reflects the onset of modern mountain building and denudation in southeast Kazakhstan, which seems to be at least partially controlled by the inherited basement architecture

Closure Time of the Junggar‐Balkhash Ocean: Constraints From Late Paleozoic Volcano‐Sedimentary Sequences in the Barleik Mountains, West Junggar, NW China

et al. 2017

View full text Add to dashboard Cite

The Junggar‐Balkhash Ocean was a major branch of the southern Paleo‐Asian Ocean. The timing of its closure is important for understanding the history of the Central Asian Orogenic Belt. New sedimentological and geochronological data from the Late Paleozoic volcano‐sedimentary sequences in the Barleik Mountains of West Junggar, NW China, help to constrain the closure time of the Junggar‐Balkhash Ocean. Tielieketi Formation (Fm) is dominated by littoral sediments, but its upper glauconite‐bearing sandstone is interpreted to deposit rapidly in a shallow‐water shelf setting. By contrast, Heishantou Fm consists chiefly of volcanic rocks, conformably overlying or in fault contact with Tielieketi Fm. Molaoba Fm is composed of parallel‐stratified fine sandstone and sandy conglomerate with graded bedding, typical of nonmarine, fluvial deposition. This formation unconformably overlies the Tielieketi and Heishantou formations and is conformably covered by Kalagang Fm characterized by a continental bimodal volcanic association. The youngest U‐Pb ages of detrital zircons from sandstones and zircon U‐Pb ages from volcanic rocks suggest that the Tielieketi, Heishantou, Molaoba, and Kalagang formations were deposited during the Famennian‐Tournaisian, Tournaisian‐early Bashkirian, Gzhelian, and Asselian‐Sakmarian, respectively. The absence of upper Bashkirian to Kasimovian was likely caused by tectonic uplifting of the West Junggar terrane. This is compatible with the occurrence of coeval stitching plutons in the West Junggar and adjacent areas. The Junggar‐Balkhash Ocean should be finally closed before the Gzhelian, slightly later or concurrent with that of other ocean domains of the southern Paleo‐Asian Ocean.
