“…Traces of this post-collisional magmatic episode (mainly A-type and (per-)alkaline magmatism) can be found in e.g. the Kyrgyz North Tien Shan (De Grave et al, 2013;Kröner et al, 2008), the Chinese Central Tien Shan (Dong et al, 2011), the Chinese West Junggar (Shen et al, 2013a) and southern Altai (Tong et al, 2014).…”

“…These episodes are in agreement with the overall timing of collisional to post-collisional magmatism and can potentially be correlated to the early (~298-296 Ma) and late (~260 Ma) Permian ZUPb ages for the Kazakh West Junggar basement from this study. Also Kröner et al (2008) and Shen et al (2013a) reported the existence of Permian anorogenic, alkaline magmatism in East Kazakhstan.…”

“…According to Shen et al (2013a) two periods of ore formation in the Kazakh North Balkhash and Chinese West Junggar occurred during the late Paleozoic. A Carboniferous (328-312 Ma) porphyry Cu metallogenic event is related to calc-alkaline arc magmatism whilst early Permian (306-289 Ma) greisen W-Mo metallogenic deposits are associated with alkaline magmatism in a collisional to post-collisional context (Shen et al, 2013a). Also Chen et al (2010Chen et al ( , 2014 confirmed that late Paleozoic felsic magmatism occurred mainly during the late Carboniferous to earliest early Permian in that region.…”

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

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 best-known ore deposits in the BMB are the super-large Kounrad and Aktogai porphyry Cu-Mo deposits, the large-scale Borly porphyry Cu-Mo deposit, the large-scale Sayak skarn Cu-polymetallic ore-field, and a series of large-scale quartz vein-type W-Mo deposits such as the East Kounrad, the Akshatau, and the Zhanet. The West Junggar metallogenic belt in northern Xinjiang, China is the eastward extension of the BMB (Chen et al, 2010;Shen and Shen, 2010;Shen et al, 2012Shen et al, , 2013.…”

“…Furthermore, there are also porphyry Borly Cu-Mo deposits and the East Kounrad, Akshatau, and Zhanet quartz vein-greisen WMo deposits in the belt. Eastwards to China, there are the Baogutu deposits in West Junggar and the TuwuYandong deposits in the East Tianshan Mountains (Seltmann and Porter 2005;Chen et al 2010;Shen et al 2013aShen et al , 2013b.…”
