The metamorphic evolution of an ancient accretionary prism in the southern zone of the Damara Belt in Namibia [PDF]

, 2013
The Southern Zone of the Damara Belt in central Namibia has an apparent stratigraphic thickness that exceeds 100 km and is comprised of highly strained, metamorphosed clastic sedimentary rocks that are intercalated with slices of metamorphosed basalt and

Collocated Geotechnical and Geophysical Test Dataset at Three Sites in Napier, New Zealand

Earthquake Spectra, Volume 42, Issue 4, November 2026.
Reliable assessment of liquefaction hazard, particularly in the context of groundwater fluctuations associated with hydroclimatic changes and variability between liquefaction assessment methods, necessitates supplementary data and advanced site characterization methods.

Geochemistry and Geochronology of the Guajira Eclogites, northern Colombia: evidence of a metamorphosed primitive Cretaceous Caribbean Island-arc

Geologica Acta, 2011
The chemical composition of eclogites, found as boulders in a Tertiary conglomerate from the Guajira Peninsula, Colombia suggests that these rocks are mainly metamorphosed basaltic andesites.

Commentary: Intense Upper Mantle Hydration of the Pacific Plate Beneath the Southern Mariana Trench

Geophysical Research Letters
To date, estimates of mantle serpentinization in trench‐outer rise regions have largely relied on Vp models from controlled‐source seismic experiments. A recent study by He et al.

The Magnetic Signature of Shear Zones in Marbles and Experimental Simulations

Geoscience Data Journal, Volume 13, Issue 4, October 2026.
This dataset explores how strain, microstructure, texture and magnetic susceptibility interact in natural and experimental shear zones. It includes data from low‐ and high‐temperature marble shear zones and analogue experiments simulating different deformation regimes.

Splay Fault Permeability Governs Fluid–Structure Interaction in Accretionary Wedges

Geophysical Research Letters
Interactions between upper plate deformation and plate interface seismicity in subduction zones remain poorly understood, but growing evidence indicates that fluid flow along splay faults modulates upper‐plate faulting.

Subduction zone magmatism

, 1995
The physical and chemical processes that occur during the subduction of two converging tectonic plates have significant consequences, contributing to both the growth of the continental crust and the chemical and thermal evolution of the Earth's interior.

Fluid Injection Triggers Large‐Scale Slow‐Slip Activation of the Rocky Mountain Fold and Thrust Belt

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Using interferometric synthetic aperture radar (InSAR) we show that hydraulic fracturing treatments near the subsurface deformation limit of the Rocky Mountain Fold and Thrust Belt produced 12 intraplate, aseismic, slow‐slip events with magnitudes Mw ${M}_{w}$ 4.71–5.06 at 1,640–2,410 m depths.

Melt‐Regulated Crustal Kinematics in the Pamir, NW Tibetan Plateau: Insights From Surface‐Wave Tomography

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract The Pamir, located at the northwestern margin of the Tibetan Plateau, is undergoing E–W extension within its interior, accommodated by micro‐block motions along major fault systems; however, the mechanisms governing this modern block kinematics remain elusive.
