Poromechanical and Crack Evolution of Olivine‐Rich Rock During Serpentinization

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Serpentinization alters the strength, fracture behavior, and rheology of ultramafic rocks, yet the coupled evolution of mineral reactions, cracking, and mechanical softening remains poorly constrained. We experimentally simulated serpentinization in dunite at 220°C and 15 MPa for 14 and 30 days and compared the reacted specimens with dry heat ...

Plate‐Scale Imaging of Eastern US Reveals Ancient and Ongoing Continental Deformation

Geophysical Research Letters
Eastern North America was constructed over several Wilson cycles, culminating in the breakup of Pangea. Previous seismological imaging lacked the resolution to depict precisely how ancient tectonic boundaries manifest throughout the lithosphere, how ...

Compositional trends of Icelandic basalts: Implications for short–length scale lithological heterogeneity in mantle plumes

Lithological variations in the mantle source regions under mid-ocean ridges and ocean islands have been proposed to play a key role in controlling melt generation and basalt composition.

Enrichment processes in the Patagonian lithospheric mantle.

, 2015
Several mantle xenolith suites entrained in basalts from back arc mafic plateau in Patagonia were investigated. They appear to be affected by both depletion processes due to melt extraction and enrichment processes. These latter are related to metasomatic and refertilization melts that, migrating through the mantle, change its composition adding ...
