Late Paleozoic tectonic evolution of the Paleo-Asian Ocean in the northern Alxa Block (NW China)

open access: yesTectonics, 2020
The northern Alxa Block occupies a key position in the southern margin of Central Asian Orogenic Belt (CAOB) and records late Paleozoic subduction and closure processes of the Paleo–Asian Ocean (PAO). However, there are still controversies regarding the timing and location of the final closure of the PAO. This study presents structural deformation data,

Subduction Initiation of the Southern Branch of the Paleo‐Asian Ocean in the Middle Ordovician in the Southern Beishan Orogen

open access: yesEarth and Space Science, 2023
AbstractThe subduction initiation and the early‐stage tectonics of the southern Paleo‐Asian Ocean have rarely been discussed. To address these problems, we report new geochemical and geochronological data of arc‐related volcanic rocks in the Huaniushan arc of the southern Beishan.

Early Permian magmatism above a slab window in Inner Mongolia, North China: Implications for the Paleo-Asian Ocean subduction processes and accretionary crustal growth

open access: yesSolid Earth Sciences, 2022
Identifying magmatic rock associations in a subduction zone is substantial for understanding the related geodynamic evolution. The final closure time of the Paleo-Asian Ocean and the exact subduction processes have continuously been controversial ...

U-Pb Isotope Geochronology of Syntectonic Granites from Hainan Island, South China: Constraints on Tectonic Evolution of the Eastern Paleo-Tethys Ocean

open access: yes, 2020
Since the recognition of the Indosinian orogeny in northern Vietnam, Triassic orogens have been widely identified around the western and southwestern boundaries of the South China block.

New insights on the early Mesozoic evolution of multiple tectonic regimes in the northeastern North China Craton from the detrital zircon provenance of sedimentary strata [PDF]

open access: yesSolid Earth, 2018
To investigate the timing of deposition and provenance of early Mesozoic strata in the northeastern North China Craton (NCC) and to understand the early Mesozoic paleotectonic evolution of the region, we combine stratigraphy, U–Pb zircon geochronology,

Late Paleozoic Southward Migration of the Dananhu Arc in the Eastern Tianshan (NW China)

open access: yesEarth and Space Science, 2022
The process of continental growth and closure of the Paleo‐Asian Ocean are controversial. To address this problem, we report new geochemical and geochronological data of granitic rocks along a N‐S corridor of the Dananhu arc. These rocks yield 401–270 Ma

Petrology, Geochronology and Geochemistry of the Xar Moron River Ophiolite: Implications for the Tectonic Evolution of the Paleo‐Asian Ocean [PDF]

open access: yesActa Geologica Sinica - English Edition, 2020
AbstractAs the largest accretionary orogen, the crustal tectonic framework and evolution of the Central Asian Orogenic Belt (CAOB) have always been one of the hot topics among geologists (Sengör et al., 1993, 1996; Jahn et al., 2000a; Badarch et al., 2002; Windley et al., 2007; Li et al., 2009).
