“…Permian mafic dyke swarms and continental basalt eruptions are widespread in the region between the Siberia and the Tarim cratons (Zhang Y P et al, 2017), composing the Central Asian rift system, from Transbaikalia and Mongolia, to the Tarim Basin (Yarmolyuk et al, 2013). For example, the Early Permian (297-290 Ma) basalts and andesites indicate post-orogenic extension in the central and eastern Kazakhstan, which is consistent with the initiation of the Tarim LIP (Khromykh et al, 2020). Associated with the Tarim LIP, post-collisional and intraplate alkali-rich volcanic rocks, A-type granitoids, continental basalts, and mafic dyke swarms, with ages of 290-270 Ma, widely developed in the Central Asia .…”

This is a review of the formation and tectonic evolution of the continental Asia in Phanerozoic. The continental Asia has formed on the bases of some pre‐Cambrian cratons, such as the Siberia, India, Arabia, North China, Tarim, South China, and Indochina, through multi‐stage plate convergence and collisional collages in Phanerozoic. The north‐central Asia had experienced the expansion and subduction of the Paleo‐Asian Ocean (PAO) in the early Paleozoic and the closure of the PAO in the late Paleozoic and early Mesozoic, forming the PAO regime and Central Asian orogenic belt (CAOB). In the core of the CAOB, the Mongol‐Okhotsk Ocean (MOO) opened with limited expansion in the Early Permian and finally closed in the Late Jurassic–Early Cretaceous. The south‐central Asia had experienced mainly multi‐stage oceanic opening, subduction and collision evolution in the Tethys Ocean, forming the Tethys regime and Himalaya‐Tibetan orogenic belt. In eastern Asia, the plate subduction and continental margin orogeny on western margin of the Pacific Ocean, forms the West Pacific regime and West Pacific orogenic belt. The PAO, Tethys, and West Pacific regimes, together with Precambrian cratons among or surrounding them, made up the major tectonic and dynamic systems of the continental Asia in Phanerozoic. Major tectonic events, such as the Early Paleozoic Qilian, Uralian, and Dunhuang orogeneses, the late Paleozoic East Junggar, Tianshan and West Junggar orogeneses, the Middle to Late Permian Ailaoshan orogeny and North‐South Lhasa collision, the early Mesozoic Indochina‐South China and North‐South China collisions, the late Mesozoic Mongolia‐Okhotsk orogeny, Lhasa‐Qiangtang collision, and intra‐continental Yanshanian orogeny, and the Cenozoic Indo‐Asian, Arab‐Asian, and West Pacific margin collisions, constrained the formation and evolution of the continental Asia. The complex dynamic systems have left large number of deformation features, such as large‐scale strike‐slip faults, thrust‐fold systems and extensional detachments on the continental Asia. Based on past tectonics, a future supercontinent, the Ameurasia, is prospected for the development of the Asia in ca. 250 Myr.

“…In the Zharma area, the Early Carboniferous (Tournaisian–Visean) sedimentary sequences (Figure 4b) contain radiolarian‐bearing chert (Iwata et al., 1997), biogenic limestone, siliceous mudstone and turbidite (Safonova et al., 2012), and they coexist with contemporaneous supra‐subduction volcanics and volcaniclastics (Safonova et al., 2018). The Late Carboniferous–Early Permian successions (Figure 4b) begin with the Moscovian molasse conglomerate above the unconformity, followed by sandstones, siltstones and coal‐bearing clays (Khromykh et al., 2020; Kuibida et al., 2019; Safonova et al., 2012). All these data suggest that the Early Carboniferous marine sedimentary environment was already replaced by a terrestrial one in the Moscovian (Khromykh et al., 2020; Safonova et al., 2012).…”

“…The associations are analogous to modern examples in Hawaii (Holcomb et al., 1988) and the Kermadec arc, New Zealand (Wright et al., 2002). On the contrary, the Late Carboniferous–Early Permian volcanic rocks are characterized by large‐scale columnar joint (Figures 9h and 9j) and accretionary lapilli (Figure 8l) and tightly coexist with terrigenous molasses (Khromykh et al., 2020; Kuibida et al., 2019), lacustrine successions (Figure 9g), plant fossil‐bearing sandstones (Figure 8m) and coal seams (Figure 8n). These are indicative of subaerial eruptions and similar to the cases in Giant's Causeway, NE Ireland (Lyle, 2000), Columbia River, NW U.S (Long & Wood, 1986; Lyle, 2000), Staffa, NW Scotland (Phillips et al., 2013) and Laacher See, West Germany (Schumacher & Schmincke, 1991).…”

“…On the other hand, the large‐scale convergence along the Irtysh‐Zaisan suture ceased at ∼320 Ma, as indicated by a Paleozoic global plate model based on high quality paleomagnetic and comprehensive geological data (Domeier & Torsvik, 2014), followed by the sluggish convergence and strike‐slip motion along the southern margin of the Siberian continent (Buslov et al., 2004; Li et al., 2017) and the northern margin of the Kazakhstan microcontinent (Choulet et al., 2011) during the Late Carboniferous to Early Permian. Furthermore, the subduction‐related magmatism occurred at the northwestern margin of the Kazakhstan microcontinent during the Devonian–Early Carboniferous (Safonova et al., 2012, 2018), but the Late Carboniferous–Permian magmatism was generated in a post‐collisional setting (Khromykh et al., 2020; Kuibida et al., 2016, 2019), suggesting the Siberia‐Kazakhstan collision in the Late Carboniferous. Therefore, the bottleneck is when the Siberian continent docked with the Kazakhstan microcontinent of eastern Laurussia and incorporated into Laurasia/Pangea.…”

The Serpukhovian–Bashkirian Amalgamation of Laurussia and the Siberian Continent and Implications for Assembly of Pangea

The final assembly of Pangea is thought to be marked by the Siberia‐Laurussia amalgamation during the Late Carboniferous–Permian, but there are large uncertainties on the timing of the amalgamation in the previous paleogeographic reconstructions because there are no high‐quality Carboniferous–Permian paleomagnetic data available from the Siberian continent. The Zharma‐Saur area in the junction between the Siberia‐Laurussia amalgamation, involving the Zharma‐Saur arc on the northern margin of the Kazakhstan microcontinent, the South Chinese Altai terrane in the southern margin of the Siberian continent and the Irtysh‐Zaisan suture in between, can provide crucial geological constraints for the assembly of Pangea. In the Zharma‐Saur arc, the Tournaisian–Visean marine sequences are interbedded with thick pillow lavas, which were formed during southward subduction of the Irtysh‐Zaisan Ocean and unconformably covered by the Moscovian terrestrial bimodal volcanic associations and sedimentary successions, in which the basalts are columnar‐jointed in structure and the sandstones also contain the detritus derived from the South Chinese Altai terrane. The Serpukhovian–Bashkirian unconformity was coeval with the transition from the Tournaisian–Visean calc‐alkaline to the Moscovian–Early Permian high alkaline and bimodal volcanism. These dramatic changes in sedimentary environments, provenances and volcanism together indicate the Siberia‐Laurussia amalgamation during the Serpukhovian–Bashkirian and this event was almost simultaneous with the Laurussia‐Gondwana collision and the welding of Laurussia with the Kazakhstan microcontinent, but slightly earlier than the Laurussia‐Tarim collision. Therefore, the final assembly of Pangea could be completed in the Late Carboniferous.
