Characterizing Patterns of Resurfacing on Venus With Volcanoes and Coronae

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract One of the major research questions for Venus is the manner in which it resurfaces itself, with a near‐random distribution of a relatively few craters providing the only age constraints for the planet's surface. We use volcanoes and their temporal and spatial relationships to coronae to characterize patterns of coronal resurfacing for ...

A Common Mantle Source for the Endogenous CO2 Degassed at the Eifel (Western Germany) and the Ardennes (Eastern Belgium) Regions

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.
Abstract Tectonic CO2 Earth degassing is globally relevant and has probably controlled climate on a geological scale (Brune et al., 2019, https://doi.org/10.1038/s41561‐017‐0003‐6). Endogenous CO2 outgassing from rifting areas remains poorly constrained, with most available data from the East African Rift.

Structure of the Mantle Keel of the Wyoming Craton and Its Relationship to Intracratonic Deformation and Magmatism

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract The Wyoming Craton is often cited as an example of decratonization, implying the removal of its lithospheric keel. However, numerous geophysical imaging studies indicate the presence of thick mantle lithosphere beneath much of the Wyoming Craton.

Near‐Synchronous Cambrian Evolution of the Transbrasiliano‐Kandi‐4°50′ Shear Zone in South America and Africa

Terra Nova, Volume 38, Issue 2, Page 97-105, April 2026.
ABSTRACT The Transbrasiliano‐Kandi‐4°50′ (TK4) shear zone in western Gondwana crosscuts South America and NW Africa for at least 6000 km. Despite its impressive size, the timing of the main episode of dextral ductile shearing is uncertain. We present detailed in situ multi‐mineral geochronology of mylonites from both Brazil and Algeria supporting that ...
