Examining Controls on Fluid Overpressure in Buried Basement Highs of Oceanic Crust: Implications for Permeability of the Astoria Fan

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 7, July 2025.
Abstract Vigorous hydrothermal circulation in the basement aquifer of the oceanic crust homogenizes temperatures within the aquifer and generates fluid overpressures at the tops of buried basement highs. At a site ∼25 km seaward of the Cascadia subduction zone deformation front, fluid overpressure at the top of the buried MARGIN seamount drives ...

Metasomatism and Melting of Cordilleran Lithosphere Resulting From Sediment Relamination During Shallow Subduction

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.

Late Cretaceous Extensional Collapse Driven by Delamination in Central Tibet Prior to India‐Asia Collision

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 7, July 2025.
Abstract A diverse range of dikes in the western Lhasa–Qiangtang collision zone provides constraints on the evolution of post‐collisional tectonomagmatic processes and the growth of the Tibetan Plateau. We report geochronological, geochemical, and Sr–Nd–Hf isotopic data for granitic dikes in the Rebang area of the Northern Lhasa Block, northern Tibet ...

The Origins of Africa's Upper Mantle Discontinuities

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 7, July 2025.
Abstract Enigmatic discontinuities in the upper mantle beneath Africa, such as the mid‐lithosphere and X‐discontinuities, have prompted various theories regarding their causes. However, most studies rely on S‐to‐P receiver functions, raising concerns about resolution.
