Constraints of middle-late Permian granites in Eastern Inner Mongolia on the final subduction of the Paleo Asian Ocean [PDF]

Scientific Reports
The Xilinhot region, located in the eastern segment of the Xingmeng orogenic belt, represents a key area for investigating the evolutionary history of the Paleo-Asian Ocean due to its close association with Late Paleozoic subduction–accretion processes ...

Survived and disappeared intra-oceanic arcs of the Paleo-Asian Ocean: evidence from Kazakhstan. [PDF]

Natl Sci Rev, 2023
ABSTRACTThis paper reviews published and presents new data on U-Pb detrital zircon ages, and petrographic, geochemical and isotope (Sm-Nd, Lu-Hf) compositions obtained from greywacke sandstones of Kazakhstan in order to reconstruct fossil intra-oceanic arcs that once existed at Pacific-type convergent margins of the Paleo-Asian Ocean (PAO) in Paleozoic

Final closure of the Paleo Asian Ocean basin in the early Triassic

Communications Earth & Environment, 2022
The suturing of the southern Altaids and final closure of the Paleo Asian Ocean within Pangea occurred during the early Triassic, according to geochemical and detrital zircon provenance analyses of sandstones in the Muzitekexie fore-arc accretionary ...

INTRA-OCEANIC ARCS OF THE PALEO-ASIAN OCEAN

Геодинамика и тектонофизика, 2017
Intra-oceanic arcs (IOAs) form at Pacific-type convergent margins, in the upper “stable” plate, when the subducting plate submerges to the depths of melting, i.e., to ca. 50–100 km.

Natural observations of subduction initiation: Implications for the geodynamic evolution of the Paleo-Asian Ocean

Geosystems and Geoenvironment, 2022
Initiation of new subduction zones is an integral part of Earth's plate tectonics regime. It is generally accepted that the negative buoyancy of sufficiently old oceanic lithosphere provides the primary driving force for subduction initiation.

Provenance of the Lower Jurassic Badaowan and Sangonghe Formations in Dongdaohaizi Depression, Junggar Basin, and Its Constraint on the Karamaili Ocean

Journal of Marine Science and Engineering, 2023
The Paleo-Asian Ocean controlled the tectonic evolution of Northeast Asia and formed the Karamaili Orogenic Belt in the eastern Junggar basin. However, the chronological constrain of the evolution of the paleo-Karamaili Ocean remains unclear.

Accreted Terranes in the Paleo‐Asian Ocean [PDF]

Acta Geologica Sinica - English Edition, 2019
AbstractTerrane accretion is considered to be one of the main contributors to the growth of continental crust (Stern and Scholl, 2010). Allochthonous terranes can be categorized into three general groups, including island arcs, seamounts (oceanic plateaus, submarine ridges), and continental fragments.

The Lithospheric Structure of the Middle Solonker−Xar Moron Suture by Surface-wave Tomography

CT Lilun yu yingyong yanjiu, 2023
The middle section of the Solonker-Xar Moron suture and its surrounding areas have successively been affected by the closure of the Paleo-Asian Ocean during the Paleozoic, the closure of the Mongolian-Okhotsk Ocean during the Mesozoic, and the subduction

Quantifying the Extent of the Paleo‐Asian Ocean During the Late Carboniferous to Early Permian

Geophysical Research Letters, 2021
AbstractDating the closure of the Paleo‐Asian Ocean (PAO) is critical to our understanding of East Asian tectonics during the formation of Pangea, yet existing estimates differ by up to 130 Myr (380–250 Ma). We report two robust paleomagnetic results from 320 to 280 Ma volcanic strata in the South Mongolia‐Xing’an Belt. Stable characteristic remanences

Crust and upper mantle electrical structure of the eastern Central Asian Orogenic Belt revealed by the MT line from Zhangwu County to East Ujimqin Banner

Earth, Planets and Space, 2022
The Central Asian Orogenic Belt is bounded on the north by the Siberian Craton and on the south by the North China Craton and the Tarim Craton. It is one of the largest Phanerozoic accretionary orogenic belts on Earth.
