Geochemistry, Geophysics, Geosystems, Volume 27, Issue 2, February 2026.Abstract The mid‐Norwegian Margin, part of the North Atlantic Igneous Province (NAIP), is a well‐studied volcanic rifted margin formed during the breakup between Greenland and Eurasia ∼56 Ma, with the largest accumulation of magmatic material hosted by the Vøring Margin section.

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 Lithospheric Drip Triggered Green and Colorado River Integration
Journal of Geophysical Research: Earth Surface, Volume 131, Issue 2, February 2026.Abstract The integration of the Green and Colorado Rivers shifted the continental drainage divide of North America, marking a key event in the hydrological and biogeographical evolution of the continent. Sedimentological and stratigraphic evidence shows that for integration to occur, the Green River likely cut through the Uinta Mountains between 8 and ...

Raising the Roof of the World: Intra‐Crustal Asian Mantle Supports the Himalayan‐Tibetan Orogen
Tectonics, Volume 44, Issue 9, September 2025.Abstract The Himalayan‐Tibetan orogen formed via the ongoing collision of India and Asia. Its colossal elevations stem from buoyant crustal roots that doubled in thickness during continental collision, widely believed to result from Indian crust under‐thrusting its Asian counterpart and Asian crustal thickening. However, a single crustal layer of up to

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 7, July 2025.Abstract Mantle xenoliths recovered from the modern backarc region of the northern Altiplano Plateau record metasomatism by slab‐derived silicic melts, and a suite of Quaternary volcanics suggest that melting of accreted crustal material has persisted since shallow subduction in the Oligocene.

Stratigraphic Revision of the Selendi, Güre, and Uşak Neogene Basins, Western Anatolia
Acta Geologica Sinica - English Edition, Volume 99, Issue 2, Page 332-351, April 2025.Abstract In a re‐examination of the Neogene stratigraphy of the Uşak, Güre, and Selendi basins of western Anatolia, western Turkey, the stratigraphic position of the previously defined İnay Group is revised, which was previously considered to be of the Middle Miocene age.

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 2, February 2025.Abstract Melting for the generation of intracontinental diffuse basaltic fields is generally ascribed to the effects from lithospheric dynamic processes, but how the asthenospheric dynamics influence the overlying lithosphere remains poorly known. Here, this is explored via a combined geochemical and numerical modeling study on the long‐lived Middle ...

Geophysical Research Letters, Volume 52, Issue 2, 28 January 2025.Abstract The temperature of the convecting mantle and thickness of the lithosphere control many of Earth's processes. However, there is disagreement regarding the evolution of these quantities through time. We use a global data set of mantle xenoliths and xenocrysts to construct paleogeotherms at different eruption ages (16–1,311 Ma) and estimate the ...

Rare‐Earth Mineralization in Dong Pao Deposit, Laichau Province, Vietnam
Resource Geology, Volume 75, Issue 1, January/December 2025.ABSTRACT The Dong Pao deposit in northern Vietnam is associated with the Paleogene Dong Pao Syenite Complex, which intruded into the limestone of the Triassic age. Although the Dong Pao deposit has been attracting exploration for decades as a promising rare earth deposit, it has not been well studied in terms of mineralization style and formation ...

Gravity field and geothermal structure of the Corsica‐Sardinia Block
Terra Nova, Volume 36, Issue 6, Page 506-515, December 2024.Abstract This paper presents a finite‐differences 3D numerical model that simulates the gravity and thermal structure of the Corsica‐Sardinia Block (CSB), an apparently stable lithospheric domain characterized by cryptic tectonic activity. In the experiments, we change the density and heat production rate of the model crust within a range of ...
