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 (

Dating the Sedimentary Protolith of the Daldyn Group Quartzite, Anabar Shield, Russia: New Detrital Zircon Constraints

Geosciences, 2020
Quartzites and paragneisses of the Archean granulite series of the Anabar Shield (Siberian Craton, Russia) are described geochemically. The Sm-Nd isotope systematics of the rocks and the U-Pb age (SHRIMP II) and geochemistry of zircons from quartzites ...

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.

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).

Rift basins of the late phanerozoic of Africa: regional patterns and conceptual development aspects

Известия высших учебных заведений: Геология и разведка
Background. This work substantiates the dependence of the development modes of rift basins of the Late Phanerozoic of Afro-Arabia on the size and age of the Lower crust structures (granulite belts) in which they were laid.

Tracing Orogenic Evolution From Multi‐Detrital Mineral Records: U‐Pb Geochronology and Trace‐Element Constraints From Glacial Diamictites

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Integrating multiple detrital mineral systems provides a powerful framework for reconstructing source‐region tectonothermal evolution because different minerals record complementary aspects of magmatic and metamorphic processes. Glacial diamictites are particularly valuable for this approach because extensive glacial erosion can sample broad ...

Mantle Wedge Metasomatism During Subduction Initiation: Mineral Transformations and Fluid Fluxes (BOIC Ophiolite, Newfoundland)

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract The soles of ophiolites preserve slices of oceanic crust metamorphosed to amphibolite‐ to granulite‐facies conditions beneath heavily deformed mantle peridotites, providing key records of fluid and mass transfer across nascent subduction interfaces.

Degradation of granulite and charnockite aggregates under simulated train loading: Morphological and mechanical insights for railway ballast

Journal of Materials Research and Technology
The performance of railway ballast strongly depends on the mineralogical and morphological characteristics of the aggregates. However, little is known about the behavior of regional rocks in Rio de Janeiro, Brazil, under manipulation caused by railway ...

Subduction Recycling and Closure of the Paleo‐Asian Ocean in the Beishan Orogen: Constraints From the Niujuanzi Ophiolitic Mélange and Associated Intrusions

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Ophiolitic mélanges and associated intrusions provide key archives for reconstructing the evolution of ancient ocean basins and subduction‐related mantle modification. The Hongliuhe–Niujuanzi–Xichangjing ophiolitic mélange in the central Beishan Orogen preserves important records of the Paleo‐Asian Ocean, but the timing of oceanic subduction ...
