“…However, most authors favor the Mongol-Okhotsk Orogeny and subsequent collapse as the main driving force for the Late Jurassic-Cretaceous cooling and denudation in the Altai, given the more proximal location of the Altai to the Mongol-Okhotsk collision zone. The widespread Cretaceous AFT ages and late Mesozoic cooling episode obtained for the Ili-Balkhash basement ranges are hence compatible with previous thermo-tectonic studies in the adjoining area, and are interpreted in the same context, mainly as far-field effects of the Cimmerian collisions at the southern Eurasian margin and possibly also of the MongolOkhotsk Orogeny in SE Siberia during the Jurassic-Cretaceous (Choulet et al, 2013;De Grave et al, 2007Dumitru et al, 2001;Hendrix et al, 1992;Jolivet et al, 2013b) (Fig. 8).…”

“…AFT dating and the sediment record is not always clear. Discrepancies between the sedimentological record and low-temperature thermochronological data in the Mesozoic are described by Jolivet et al (2010) for the Chinese IIi Basin, and by Jolivet et al (2013b) and Vincent and Allen (2001) for the Junggar Basin. Also, Jolivet et al (in press) demonstrate that the link between tectonic uplift and the sediment record is often not straightforward, and can be considerably modified by climate variations as in the case of the Upper Jurassic-Lower Cretaceous alluvial fan deposits of the Kalaza Formation for example.…”

“…In addition, far-field effects of the MOOB to the NE of the study area during the Jurassic-Cretaceous cannot be excluded, although its extent and influence is at present highly contested (e.g. Jolivet et al, 2010Jolivet et al, , 2013aJolivet et al, , 2013bMetelkin et al, 2010;Wilhem et al, 2012 and references therein). In the southern Altai Mountains, several AFT studies point to a Late Jurassic-Cretaceous basement cooling event, which is generally linked to both the Mongol-Okhotsk and the Cimmerian Orogeny during the Mesozoic (Cogné et al, 2005;De Grave et al, 2007Glorie et al, 2012aGlorie et al, , 2012bHalim et al, 1998;Yuan et al, 2006).…”

“…De Grave et al, 2013;Jolivet, in press;Jolivet et al, 2010Jolivet et al, , 2013b. Evidence for these reactivation episodes is often documented in the cooling histories of the exhumed basement rocks and in the sediments of the intervening basins, but the extent of these reactivation events is still under discussion (e.g.…”

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

The geological evolution of Central Asia commenced with the evolution of a complex Precambrian–Palaeozoic orogen. Cimmerian blocks were then accreted to the southern margin during the Mesozoic, leading to tectonic reactivation of older structures and discrete episodes of basin formation. The Indian and Arabian blocks collided with Asia during the Cenozoic, leading to renewed structural reactivation, intracontinental deformation and basin development. This complex evolution resulted in the present-day setting of an elongated Tien Shan range flanked by large Mesozoic–Cenozoic sedimentary basins with smaller intramontane basins distributed within the range. The aim of this volume is to present multidisciplinary results and reviews from research groups in Europe and Central Asia that focus on the western part of the Tien Shan and some of the large sedimentary basins in that area. These works elucidate the Late Palaeozoic–Cenozoic tectono-sedimentary evolution of the area. Emphasis is placed on the collision of terranes and/or continents and the ensuing fault reactivation; the impact of changes in climate on the sedimentation is also examined.

Cenozoic intracontinental deformation and exhumation at the northwestern tip of the India-Asia collision-southwestern Tian Shan, Tajikistan, and Kyrgyzstan

Along the Ghissar-Alai Range of the southwestern Tian Shan (southwestern Kyrgyzstan, northern Tajikistan), the deformation front of the India-Asia collision-the Pamir-Tibet orogen-is interacting with the intracontinental Tian Shan orogen without the intervening Tarim Craton. Apatite fission track (n = 33,~3.3-145.6 Ma, 27% <10 Ma) and (U-Th)/He (n = 32,~1.9-26.1 Ma, 56% <10 Ma) thermochronologic ages suggest approximate isothermal holding (very slow cooling to weak reheating) during relative tectonic quiescence between~150 and 15 Ma. Accelerated exhumation (~0.2-1.0 km/Myr, median~0.5 km/Myr) and cooling (11-16°C/Myr) occurred over the last~10 Myr. Geomorphologic parameters-incision, river steepness, and concavity-confirm the youth of the southwestern Tian Shan's mountain building. High exhumation/cooling rates are correlated with pronounced local relief, produced by Cenozoic faults reactivating inherited (Late Paleozoic) structures. Regions with similarly young exhumation are centered along rims of rigid crustal blocks in the central and eastern Tian Shan. Structurally, the Ghissar-Alai Range is a broad, east trending zone of dextral transpression that includes the northern Tajik Basin (Illiak Fault Zone) and the Pamir Thrust System of the frontal northern Pamir. It is the particular deformation field at the northwestern tip of the India-Asia collision-the interaction of the westward gravitational collapse of the Pamir Plateau into the Tajik Basin with the bulk northward motion of the Pamir-that transformed the southwestern Tian Shan into a dextral transpression belt. The dextral transpression in the southwestern Tian Shan contrasts with sinistral strike-slip shear localized along inherited fault zones, accommodating dominant north-south shortening, in the central and eastern Tian Shan. The deformation field influenced by the Pamir and the associated young exhumation make the Ghissar-Alai Range a unique feature in the Tian Shan orogen.
