“…Xie, Luo, et al () provide no field photographs or photomicrographs of their ignimbrites. Correlative ignimbrites from the north limb of the Bogda Mountain anticline (Xie, Xu, et al, ) appear to be crystal or crystal‐vitric tuffs, commonly thin bedded, and no evidence is presented of welding of glassy clasts or thick cooling units. We prefer the IUGS term tuff, or pyroclastic flow tuff, for such rocks.…”

“…It has been proposed that magmatic activities within intercontinental extension‐rift structures exhibit alkaline affinity during the initial stage and gradually develop calc‐alkaline to tholeiitic characters when the rift matures (Palinkaš et al, ; Pamic, ). The Liushugou Formation on the northern limb of the Bogda Mountain anticline, dated at 315 to 319 Ma, is composed principally of trachyte–andesite to trachyte pyroclastic rocks (Xie, Xu, et al, ) that may represent the alkaline stage of magmatism in the basin. The 1,500‐ to 2,500‐m water depth of the basin in the Qijiagou Formation and the lack of crustal contamination may indicate a residual ocean basin (such as the Black and southern Caspian seas) or an oceanic back‐arc basin (such as the Tyrrhenian Sea) in a regionally extensional environment.…”

Facies architecture of a subaqueous volcano–sedimentary succession on Bogda Mountains, NW China—Evidence of extension in Late Carboniferous

A Late Carboniferous volcano–sedimentary complex outcrops on the southwestern flank of the Bogda Mountains, NW China. The volcanic architecture, spatial relationships, and emplacement mechanisms of the lithofacies were studied in detail, providing a lithofacies context for previously published structural and geochemical studies and constraining the reconstruction of palaeo‐environments. Four distinct volcano–sedimentary facies are identified in the Qijiagou Formation: close‐packed pillow basalts, pillow basalts with interstitial sediments, hyaloclastites, and peperites. Textural features of the lithofacies, especially hyaloclastites and peperites, provide clear evidence for in situ fragmentation of lava flows, co‐volcanic sedimentation of limestone, and intimate interaction between lava, water, and sediments. They demonstrate autochthonous, subaqueous origin of the succession. Discovery of peperites and stratigraphic transitions of the related lithofacies indicate a progressively deepening subaqueous environment, resembling a volcanic evolution from early stage of eruption at a shallower level to increasingly subsiding basin with increasing eruption frequency of basaltic lava at greater water depth. Vesicularity of basalts, ambient pressure, and peperitic features indicate eruption depth at between 1,500 and 2,500 m. The deep extensional basin in the Baiyanggou area was coeval with bimodal volcanism, uplift, and granite intrusion along strike in the region, all indicating continental collision and post‐collisional extension. The substantial depth of the Baiyanggou Basin indicates that it may have been a back‐arc or even a residual oceanic basin.

“…At the end of the Early Permian, the shallow water deposited sandstone directly overlying on the mudstone. The depositional environment transitioned from deep water environment to shallow water environment [73,74]. Further, the depositional environment was transferred from marine to nonmarine environment in the Middle Permian with the main lithology of fine sandstone, mudstone and oil-bearing mudstone.…”

“…From this collision, the tectonic setting of West Bogeda Shan changed to intracontinental tectonic evolution stage, and the original terrain of West Bogeda formed (Figure 13b). At the end of the Early Permian, most parts of the terrain were still a submarine environment, while only small parts were lifted up [32,74,[83][84][85]. distribution of bimodal volcanic rocks in the Bogeda Shan [73] and some submarine olistostrome in the West Bogeda Shan [30].…”

The Bogeda Shan (Mountain) is in southern part of the Central Asian Orogenic Belt (CAOB) and well preserved Paleozoic stratigraphy, making it an ideal region to study the tectonic evolution of the CAOB. However, there is a long-standing debate on the tectonic setting and onset uplift of the Bogeda Shan. In this study, we report detrital zircon U-Pb geochronology and whole-rock geochemistry of the Permian sandstone samples, to decipher the provenance and tectonic evolution of the West Bogeda Shan. The Lower-Middle Permian sandstone is characterized by a dominant zircon peak age at 300–400 Ma, similar to the Carboniferous samples, suggesting their provenance inheritance and from North Tian Shan (NTS) and Yili-Central Tian Shan (YCTS). While the zircon record of the Upper Permian sandstone is characterized by two major age peaks at ca. 335 Ma and ca. 455 Ma, indicating the change of provenance after the Middle Permian and indicating the uplift of Bogeda Shan. The initial uplift of Bogeda Shan was also demonstrated by structural deformations and unconformity occurring at the end of Middle Permian. The bulk elemental geochemistry of sedimentary rocks in the West Bogeda Shan suggests the Lower-Middle Permian is mostly greywacke with mafic source dominance, and tectonic setting changed from the continental rift in the Early Permian to post rift in the Middle Permian. The Upper Permian mainly consists of litharenite and sublitharenite with mafic-intermediate provenances formed in continental island arcs. The combined evidences suggest the initial uplift of the Bogeda Shan occurred in the Late Permian, and three stages of mountain building include the continental rift, post-rift extensional depression, and continental arc from the Early, Middle, to Late Permian, respectively.

“…The Bogda belt is predominantly composed of Carboniferous strata, including Lower Carboniferous marine volcanic ignimbrite, tuffaceous sandstone, and volcanic lava and Upper Carboniferous shallow marine limestone and clastic sediments, associated with submarine basalt, andesite, rhyolite, and felsic ignimbrite (Xia et al, 2004;Xia, Xia, Xu, Li, & Ma, 2008;Xie et al, 2016). The Permian-Mesozoic strata are discontinuously distributed along the piedmont of the Bogda belt, consisting of Lower Permian terrestrial clastic sediments intercalated with bimodal volcanic lava and Middle Permian-Mesozoic terrestrial clastic sediments (Tang et al, 2014;Xia et al, 2008;Xie et al, 2016). In brief, intensive Late Palaeozoic magmatism occurred in the Bogda belt and lasted from 350 to 280 Ma (Wali, Wang, Cluzel, & Zhong, 2018).…”

Detrital zircon U–Pb geochronology of the Permian strata in the Turpan–Hami Basin in North Xinjiang, NW China: Depositional age, provenance, and tectonic implications

et al. 2018

The Permian sedimentary rocks in the Turpan–Hami Basin are key records of the tectonic evolution in the Eastern Tianshan area, although their depositional ages and provenances remain relatively less studied. Here, we conducted detrital zircon U–Pb geochronology on subsurface samples collected from Well LN1 in the Turpan–Hami Basin to understand the depositional ages and provenances of the Permian rocks. In this study, detrital zircon U–Pb ages from the Late Carboniferous Sumuke Formation yielded a notable Permian age population with the youngest single‐grain age at 282.6 Ma. Compiling this result with a published dataset from the surrounding regions of the Turpan–Hami Basin, it shows that the Sumuke Formation was actually deposited in the Early Permian and the Late Carboniferous palynological assemblages within it are of recycled origin. The detrital zircon age spectra of the three Early–Middle Permian samples from Well LN1 define similar unimodal distribution, with prominent late Carboniferous age peaks and scarce Precambrian ages, further indicating that the zircon grains in these three samples should be ultimately sourced from the Jueluotag, the southern branch of the North Tianshan. Regionally, the Bogda, the northern branch of the North Tianshan, as catchment areas recorded interaction between southern and northern sources, and thus, there was a single greater Junggar–Turpan Basin during the Early–Middle Permian. During the latest Middle Permian to Late Permian, provenance shifts occurred at the Jueluotag and the southern piedmont of the Bogda, reflecting the uplift of the Central Tianshan and the Bogda and the isolation of the Junggar Basin and Turpan–Hami Basin. Integrating regional geological studies and provenance evolution trends, we suggest that the Turpan–Hami Basin and its surrounding regions were in a rift setting controlled by post‐collision extension during Early–Middle Permian. By contrast, tectonic contraction and inversion occurred during the latest Middle Permian to Late Permian as a part of the intraplate orogenic process in the Tianshan, which responded to the convergence between the Songpan–Ganzi terrane and palaeo‐Eurasian Plate.
