Geochemistry and geochronology of the Delinggou Intrusion: Implications for the subduction of the Paleo-Asian Ocean beneath the North China Craton

Gondwana Research, 2017
Abstract The formation and evolution of the Central Asian Orogenic Belt (CAOB) are intimately related to the opening and closure of the Paleo-Asian Ocean. The final closure led to amalgamation or collision between the CAOB and North China Craton. However, the issue about the subduction polarity and final closure of the Paleo-Asian Ocean has long been

Permian to Cretaceous tectonic evolution of the Jiamusi and Songliao blocks in NE China: Transition from the closure of the Paleo-Asian Ocean to the subduction of the Paleo-Pacific Ocean

open access: yesGondwana Research, 2022
Zhangguangcailing Orogen constitutes a significant part of the Eastern Asian Continental margin. Its evolution was constrained by the oceanic consumption processes between the Jiamusi and Songliao blocks during late Paleozoic and Mesozoic time, resulted ...

Influence of subducted carbonate on the composition of basalts in the Paleo-Asian Ocean domain

open access: yesGondwana Research, 2023
The fate of subducted carbonate of the Paleo-Asian Ocean and its control on the compositional variability of Cenozoic basalts to the west of the Daxing'anling-Taihang Gravity Lineament remain uncertain.

Final amalgamation of the Central Asian Orogenic Belt in NE China: Paleo-Asian Ocean closure versus Paleo-Pacific plate subduction — A review of the evidence

open access: yesTectonophysics, 2015
The Central Asian Orogenic Belt (CAOB) evolved through complex closure of the Paleo-Asian Ocean from the Neoproterozoic to the late Phanerozoic. This caused the Chinese cratons to collide with Eurasia and led to the formation of the world's largest ...

From Cambrian subduction initiation to Carboniferous mantle plume−related DUPAL magmatism in the Paleo-Asian Ocean

open access: yesGeological Society of America Bulletin
Understanding subduction initiation and mantle plume dynamics is central to plate-tectonic evolution but remains poorly constrained in ancient orogens. The tectonic evolution of the North Tianshan paleo-ocean basin, a key segment of the Paleo-Asian Ocean of the Altaids, has long been debated owing to the scarcity of diagnostic ophiolitic records.

Final Closure of the Paleo‐Asian Ocean and Onset of Subduction of Paleo‐Pacific Ocean: Constraints From Early Mesozoic Magmatism in Central Southern Jilin Province, NE China

open access: yesJournal of Geophysical Research: Solid Earth, 2019
When the Paleo-Asian Ocean closed and the Paleo-Pacific subduction started in NE China remains controversial. To constrain these key issues, we carried out zircon U-Pb-Hf isotopic and whole-rock geochemical studies of Early Mesozoic igneous rocks in ...

Crustal-scale Seismic-reflection Profiling Constrains How the Paleo-Asian Ocean Was Closed

Tectonics, 2023
AbstractThe Central Asian Orogenic Belt (CAOB) is the most significant accretionary orogenic belt since the Phanerozoic and the most ideal site for studying continental growth evolution processes. A 460‐km‐long high‐resolution crustal‐scale seismic reflection study was conducted across the eastern CAOB in North‐Central China to constrain the closure ...

Opening and Tectonic Evolution of the Paleo-Asian Ocean

International Geology Review, 1995
The Paleo-Asian ocean is defined by units located between the Russian (East European), Siberian, Tarim, and Sino-Korean (North China) continents. The study of the composition, age, and structural position of island-arc magmatic rocks, ophiolites, and high-pressure meta-morphic assemblages and their mutual correlations made it possible to identify ...
