Influence of loading and heating processes on elastic and geomechanical properties of eclogites and granulites

Journal of Rock Mechanics and Geotechnical Engineering, 2018
Increased knowledge of the elastic and geomechnical properties of rocks is important for numerous engineering and geoscience applications (e.g. petroleum geoscience, underground waste repositories, geothermal energy, earthquake studies, and hydrocarbon ...

A Geophysical Crustal Model of Central Italy for Geoneutrino Predictions in Borexino

Earth and Space Science, Volume 13, Issue 11, November 2026.
Abstract Predicting the geoneutrino signal at underground detectors requires a local crustal reference whose precision matches the experimental uncertainty. The current Borexino reference is 15 years old and deterministic. We replace it with GUESS, a probabilistic 3‐D model of the Gran Sasso region, built by Bayesian inversion of multi‐source ...

Geochemical Characteristics of Metasediment—Rich Lower Continental Crust: Insights From the Ivrea‐Verbano Zone (DIVE Drilling Project, ICDP Expedition 5071, Val d’Ossola, Italy)

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 11, November 2026.
Abstract Whole‐rock geochemical data from two drill cores obtained through the ICDP (International Continental Scientific Drilling Program) funded Drilling the Ivrea‐Verbano Zone (IVZ) (DIVE) project: 5071_1_B (Ornavasso) and 5071_1_A (Megolo), provide new insights into the composition of the lower continental crust (LCC) in the IVZ. Borehole 5071_1_B (

Constraints on the rheology of the lower crust in a strike-slip plate boundary: evidence from the San Quintín xenoliths, Baja California, Mexico [PDF]

Solid Earth, 2017
The rheology of lower crust and its transient behavior in active strike-slip plate boundaries remain poorly understood. To address this issue, we analyzed a suite of granulite and lherzolite xenoliths from the upper Pleistocene–Holocene San Quintín ...

Paleomagnetism of the Scourie Dykes, Lewisian Foreland, NW Scotland: Constraints on Early Paleoproterozoic Paleogeography of Kenorland

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract The Scourie dyke swarm in the Lewisian foreland of northwest Scotland provides key constraints on the Paleoproterozoic evolution of the North Atlantic craton. High‐precision U‐Pb geochronology identifies two distinct intrusive phases at ∼2.41–2.38 Ga and ∼2.00 Ga.

Mid-crustal shear zone development under retrograde conditions: pressure–temperature–fluid constraints from the Kuckaus Mylonite Zone, Namibia [PDF]

Solid Earth, 2016
The Kuckaus Mylonite Zone (KMZ) forms part of the larger Marshall Rocks–Pofadder shear zone system, a 550 km-long, crustal-scale strike-slip shear zone system that is localized in high-grade granitoid gneisses and migmatites of the Namaqua Metamorphic ...

Sensitization of OSL Signals in Quartz and Provenance Implications: Insights From Multi‐Spectroscopic Analysis of Quartz From Multiple Geological Settings

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 10, October 2026.
Abstract Quartz optically stimulated luminescence (OSL) sensitivity and electron spin resonance (ESR) signals have been empirically proposed as indicators of sediment provenance. OSL sensitivity is defined as luminescence produced per unit dose (Gray: Gy) per unit mass (mg).
