Hidden Eoarchean crust in the southwestern Central Asian Orogenic Belt

Lithos, 2020
Abstract U-Pb and Hf-isotope analyses of zircon xenocrysts from drilling-sampled Carboniferous volcanic rocks suggest the presence of unexposed Eoarchean crust beneath the Junggar Basin (NW China), southwestern Central Asian Orogenic Belt (CAOB). The oldest zircon population with U-Pb ages of 3.8 Ga shows chondritic eHf(t) of −0.7 to +0.7, and Hf ...

The Dunhuang block is a Paleozoic orogenic belt and part of the Central Asian Orogenic Belt (CAOB), NW China

Gondwana Research, 2016
Abstract The Dunhuang region is located in the east of the Tarim Craton and has long been considered as part of a Precambrian terrane of the Tarim or North China Craton. Aiming to further understand the tectonic evolution of the Dunhuang region and its relations with the adjacent tectonic units, this study is to investigate the metamafic rocks in the

The Origin and Crustal Evolution of Microcontinents in the Beishan Orogen of the Southern Central Asian Orogenic Belt

Earth-Science Reviews, 2018
Abstract Microcontinents with Precambrian basement have played an important role in the accretionary and amalgamation history of the Central Asian Orogenic Belt (CAOB). However, their geological evolution is only poorly constrained due to restricted exposure of the Precambrian rocks, which were extensively overprinted mainly by Paleozoic tectonic ...

Granitoids of the Central Asian Orogenic Belt and continental growth in the Phanerozoic

Earth and Environmental Science Transactions of the Royal Society of Edinburgh, 2000
The Central Asian Orogenic Belt (CAOB), also known as the Altaid Tectonic Collage, is characterised by a vast distribution of Paleozoic and Mesozoic granitic intrusions. The granitoids have a wide range of compositions and roughly show a temporal evolution from calcalkaline to alkaline to peralkaline series.

Accretionary processes and metallogenesis of the Central Asian Orogenic Belt: Advances and perspectives

Science China Earth Sciences, 2020
As one of the largest Phanerozoic orogens in the world, the Central Asian Orogenic Belt (CAOB) is a natural laboratory for studies of continental dynamics and metallogenesis. This paper summarizes the research progresses of the accretionary processes and metallogenesis of the CAOB since the People’s Republic of China was founded, and puts forward the ...

A Study of Orogenic Processes: The Tectonic Evolution of the Eastern Central Asian Orogenic Belt

Tectonics
Abstract The Great Xing'an Range (GXR) is a critical contentious region within the eastern Central Asian Orogenic Belt (CAOB), recording complex interactions among the Paleo‐Asian, Mongol‐Okhotsk, and Paleo‐Pacific Oceans since the Paleozoic.

Multiscale geophysical characterization of the continental crust of the Central Asian Orogenic Belt

2023
The Central Asian Orogenic Belt (CAOB) is a Paleozoic accretionary-collisional orogen located at the eastern Pangea in between the Siberian Craton to the north and the North China and Tarim cratons to the south. Several contradictory geodynamic models were proposed to explain the tectonic assemblage: oroclinal bending and strike-slip duplication of a ...

Ediacaran to Paleozoic magmatism in West Junggar Orogenic Belt, NW China, and implications for evolution of Central Asian Orogenic Belt

Lithos, 2019
Abstract The formation of the Central Asian Orogenic Belt is thought to be related to the evolution of the Paleo-Asian Ocean surrounded by the Siberian, European, and Tarim-North China cratons. The West Junggar Orogenic Belt (WJOB) in the southern Central Asian Orogenic Belt is part of the Kazakhstan-Junggar terrane between the Altay Orogenic Belt to
