Unravelling the 800‐million‐year geological history of the Nevis and Mamore ranges, Fort William, Scotland

Geology Today, Volume 42, Issue 2, Page 97-111, March/April 2026.
The Nevis and Mamore ranges near Fort William comprise some of the most popular and spectacular of all Scotland's mountains including the highest peak, Ben Nevis. The beauty of this mountainous region is the product of a long and complex geological evolution, spanning 800 million years of Earth's history.

Novel Crushing Technique for Measuring δ18O and δ2H Values of Fluid Inclusions (H2O) in Quartz Mineral Veins Using Cavity Ring-Down Spectroscopy

Geofluids
Fluid inclusions in mineralized fracture infillings (i.e., veins) could preserve information about subsurface fluids like temperature and salinity.

Crustal Structure of Laurentia and Peri‐Gondwanan Terranes Beneath Ireland and Britain and Comparison With Eastern North America

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract The Appalachian‐Caledonian orogen was built during the Paleozoic by accretion of peri‐Gondwanan terranes onto Laurentia, culminating in the formation of Pangea. During the Mesozoic, Pangea broke apart, displacing one section of the belt to eastern North America and another to northwestern Europe.

Orthogonal extensional quartz veins in a famous 'Chocolate-Tablet Structure' from Almograve (SW Portugal), associated with early Variscan Orogeny

Orthogonal vein sets, orientated perpendicularly to the bedding, are present in fold-and-thrust belts; yet the date of their origin in relation to orogeny is ambiguous.

Fracture‐Assisted Pressure Solution Creep of Granite: An Example From the Mont Blanc Massif, Western Alps

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract The Mont Blanc granite, as other deformed granites, has splitting properties attributed to two perpendicular planes: one formed by aligned fractures and the other by aligned micas in foliation planes. It is shown that this microstructure results from ductile deformation with stress‐driven dissolution of quartz and feldspar that passively ...

Variscan collisional magmatism and deformation in NW Iberia: Constraints from U-Pb geochronology of granitoids

, 2000
U–Pb geochronology of Variscan granitoid rocks from the West Asturian Leonese Zone of the NW Iberian belt documents the episodic nature of magmatism in this section of the western European Variscides.

Evolution and Provenance of the Polish Rotliegend in the Southern Permian Basin

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 2, February 2026.
Abstract The Southern Permian Basin (SPB) has been extensively explored for ore deposits. However, a comprehensive evaluation of the remaining copper potential, specifically for sediment‐hosted stratiform copper system, remains lacking. This study applies goSPL, an open‐source landscape and stratigraphic evolution model, to reconstruct the Permian rift‐

The transition from Variscan collision to continental break-up in the Alps: advice from the comparison between natural data and numerical model predictions

, 2014
Records of Variscan structural and metamorphic imprints in the Alps indicate that before Pangaea fragmentation, the continental lithosphere was thermally and mechanically per- turbed during Variscan subduction and collision.

New palaeobotanical data from Carboniferous Culm deposits constrain the age of the Variscan deformation in the eastern Pyrenees

Geologica Acta, 2018
The pre-Variscan rocks of the Pyrenees exhibit a polyphase deformation linked to the Variscan crustal shortening and a low-pressure–high-temperature metamorphism. However, there is scarce chronostratigraphic evidence of this Variscan deformation. In the
