Evolution of the Transantarctic Basin (Southern Gondwana): Insights From Quantitative Sandstone Petrography

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
The deposition of the sandstone sedimentary succession of the Beacon Supergroup lasted more than 200 Myr (Devonian to Early Jurassic) in Victoria Land and nearby territories in the so‐called Transantarctic Basin, recording crucial events in the history of the Earth.

Oxidation State of the Lithospheric Mantle Beneath Komsomolskaya–Magnitnaya Kimberlite Pipe, Upper Muna Field, Siberian Craton

, 2020
The oxidation state of the mantle plays an important role in many chemical and physical processes, including magma genesis, the speciation of volatiles, metasomatism and the evolution of the Earth’s atmosphere. We report the first data on the redox

Low Water Content of the Lower Continental Crust Induced by Decompression Melting: Evidence From the Weichang Granulite Xenoliths in the Northern North China Craton

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 2, February 2026.
Abstract The water content of granulite xenoliths from the Cenozoic Weichang basalts in the northern North China Craton (NCC) is investigated to constrain the nature and evolution of the lower crust. Granulites are categorized into felsic and mafic groups, characterized by widely developed glass‐bearing sieve textures in their constituent minerals ...

Reconciling Seismic and Thermo‐Chemical Models of Cratonic Lithosphere

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 2, February 2026.
Abstract Most published global and regional shear‐wave (VS ${V}_{\mathrm{S}}$) velocity models of cratons include a VS ${V}_{\mathrm{S}}$ increase with depth below the Moho, with a maximum at 100–150 km depth. This feature has long been debated, as it appears to require either (implausible) temperature decreases with depth, or substantial, layered ...

A review on the magnetotelluric studies over the Central Asian Orogenic Belt—recent developments and future aspects

Frontiers in Earth Science
The Central Asian Orogenic Belt (CAOB) was originated from the subduction, closure, convergence, and post-collisional extension of the Paleo-Asian Ocean located between the North China Craton, Tarim Craton, and the Siberian Craton during the late Permian

The Mesoproterozoic mantle plume beneath the northern part of the Siberian craton

, 2016
The study of the Mesoproterozoic (1473 ± 24 Ma) dolerites of the Olenek uplift of the Siberian craton basement has shown their petrologic and geochemical similarity to typical OIB produced with participation of a mantle plume.

The Proterozoic evolution of northern Siberian Craton margin: a comparison of U–Pb–Hf signatures from sedimentary units of the Taimyr orogenic belt and the Siberian platform [PDF]

, 2017
Identifying the cratonic affinity of Neoproterozoic crust that surrounds the northern margin of the Siberian Craton (SC) is critical for determining its tectonic evolution and placing the Craton in Neoproterozoic supercontinental reconstructions ...

Protracted intercontinental aridification preserved within the early Late Cretaceous strata of the Eastern Gobi Basin, Mongolia

Sedimentology, Volume 73, Issue 1, Page 147-185, January 2026.
ABSTRACT Mongolia's Eastern and Western Gobi Basins preserve a globally significant record of Cretaceous terrestrial vertebrates, yet their biostratigraphic correlations are complicated by a complex geological history. The Eastern Gobi Basin, a northeast‐southwest trending fault‐bounded rift system, includes several minor sub‐basins with distinct ...
