The Altai-Mongolia terrane in the Central Asian Orogenic Belt (CAOB): A peri-Gondwana one? Evidence from zircon U–Pb, Hf isotopes and REE abundance

Precambrian Research, 2011
Abstract Understanding the tectonic nature of the Altai-Mongolia terrane is significant in tectonic reconstruction of the Central Asian Orogenic Belt (CAOB), a Paleozoic accretionary one similar to the present-day SW Pacific archipelago. Uncertainty in stratigraphic frame of this terrane has led to many controversies in tectonic interpretation.

Comparison between the Permian mafic dykes in Tarim and the western part of Central Asian Orogenic Belt (CAOB), NW China: Implications for two mantle domains of the Permian Tarim Large Igneous Province

Lithos, 2013
Abstract Ages and chemical and isotopic compositions of the Permian mafic dyke swarms from Kelamayi, eastern Tianshan and western Tianshan in western part of the Central Asian Orogenic Belt (CAOB), NW China, are reported here in order to gain more insights into the Permian Tarim Large Igneous Province (Tarim LIP).

Constraining The Ages Of Late Devonian Extinction Events In The Central Asian Orogenic Belt (CAOB): U-Pb Geochronology And Igneous Petrology

, 2019
The Late Devonian was a time of drastic changes in climate and biodiversity. Two of the top six most devastating extinction events occurred during the Late Devonian, although the reasons for these extinction events remains unknown. More than 96% of studies on these Late Devonian extinction intervals have been conducted on continental margins or in ...

Missing adakitic granite and syn-subduction mafic dikes within Permian volcanic belts of the southern margin of the CAOB? Comment on “Permian oceanic slab subduction in the southernmost Central Asian Orogenic Belt: Evidence from adakite and high-Mg diorite in the southern Beishan”

Lithos, 2022
Abstract The petrogenesis of adakite and adakitic rocks and their tectonic settings are debated. Adakites may be derived by many processes which include: partial melting of subducted oceanic slab or lower crustal material; fractional crystallization of basaltic magma; magma mixing processes associated with arc-related and non-arc tectonic settings ...

Paleozoic tectonothermal event in Mt. Dongbatu, Dunhuang terrane, southernmost Central Asian Orogenic Belt (CAOB): Implications for petrogenesis and geological evolution

Lithos, 2019
Abstract In this contribution, systematic petrographical, whole-rock geochemical, geochronological and zircon Lu-Hf isotopic investigations were conducted on Paleozoic (ca. 410–400 Ma) metamorphic-magmatic rocks from Mt. Dongbatu in the central Dunhuang terrane.

Age and geochemistry of the Zhaheba ophiolite complex in eastern Junggar of the Central Asian Orogenic Belt (CAOB): implications for the accretion process of the Junggar terrane

Geological Magazine, 2016
AbstractWe report new field observations, zircon U–Pb ages and geochemical data for the discrete members of the Zhaheba ophiolite complex in northeastern Junggar of the Central Asian Orogenic Belt (CAOB) with the aim to understand the accretion process of the eastern Junggar terrane.

Ancient sub-continental lithospheric mantle (SCLM) beneath the eastern part of the Central Asian Orogenic Belt (CAOB): Implications for crust–mantle decoupling

Lithos, 2011
Abstract Potassic basaltic lavas erupted during the Cenzoic are widespread in Wudalianchi, Erkeshan and Keluo (WEK) areas, northeast China, and contain abundant mantle xenoliths. Mantle xenoliths in this study are selected from the Keluo potassic lavas, and mainly comprise spinel lherzolites and harzburgites with minor dunites and wehrlites.
