The composite Sierra Bermeja Pluton (southern Iberian Massif): science, heritage and geoconservation

Journal of Maps, 2019
The Sierra Bermeja Pluton (∼60 km2 surface area) exemplifies a type of controversial granites of the Iberian Massif (European Variscan Belt), the cordierite-bearing ‘Serie Mixta’ (mixed series) monzogranites.

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.

Geothermal Modelling of Variscan EGS in Granitic and Metamorphic Rocks

, 2019
This study, as a part of the EU funded project MEET Multidisciplinary and multi-context demonstration of EGS exploration and Exploitation Techniques and potentials, aims to minimize the uncertainity in geology at greater depths by providing high quality datasets measured on both field analogues and drillcore samples of potential reservoir rocks ...

Contrasting crustal sources for peraluminous granites of the segmented Montes de Toledo Batholith (Iberian Variscan Belt)

, 2008
The Variscan Montes de Toledo Batholith (MTB) is an E–W linear array of peraluminous granite plutons which is chemically segmented. The study is focused on the western segment of the MTB (W-MTB), mainly composed of granites with slightly lower CaO and ...

The importance of sequential partial melting and fractional crystallization in the generation of syn-D3 Variscan two-mica granites from the Carrazeda de Ansiães area, northern Portugal

, 2021
In the Carrazeda de Ansiães region, northern Portugal, a mesozonal granitic suite intruded Precambrian to Ordovician metasedimentary rocks during the late kinematic stages of the Variscan orogeny.

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 ...

The emplacement age of the Muntele Mare Variscan granite (Apuseni Mountains, Romania)

Geologica Carpathica, 2009
The emplacement age of the Muntele Mare Variscan granite (Apuseni Mountains, Romania)Like the Alps and Western Carpathians, the Apuseni Mountains represent a fragment of the Variscan orogen involved in the Alpine crustal shortenings. Thus the more extensive Alpine tectonic unit in the Apuseni Mountains, the Bihor Autochthonous Unit is overlain by ...

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‐

Poly-Orogenic Melting of Metasedimentary Crust From a Granite Geochemistry and Inherited Zircon Perspective (Southern Calabria-Peloritani Orogen, Italy)

Frontiers in Earth Science, 2019
Inherited zircon ages and geochemical features of late Cadomian and late Variscan granitoids from the north-eastern Peloritani Mountains (NE Sicily) and the western Aspromonte Massif (SW Calabria) shed new light on the sources and processes involved in ...
