Two metamorphic cycles recorded by monazite in eclogite-facies gneisses (Southern Armorican Massif, France): A Cambro-Ordovician continental crust involved in eo-Variscan subduction

BSGF - Earth Sciences Bulletin
We present U-Th/Pb data obtained for xenotime and monazite from the polycyclic eclogite-facies para- and ortho-gneisses of the Les Essarts Unit (Vendée, southern Armorican Massif, France), which have recorded an HT-LP cycle ending with a first ...

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‐

Evidence of a Paleoproterozoic basement in the Moroccan Variscan Belt (Rehamna Massif, Western Meseta)

, 2016
For the first time, an Eburnian magmatic event has been identified in the Rehamna Massif (Moroccan Variscan Belt, Western Meseta) located north of the South Meseta fault.

Strain partitioning within bending orogens, new insights from the Variscan belt (Chiroulet‐Lesponne domes, Pyrenees)

, 2021
International audienceThis study investigates how strain is partitioned within hot orogenic belts in a context of plate-reorganization. We document crustal-scale strike-slip shear zones, plate-scale oroclinal bending, and widespread exhumation of deep ...

Age and provenance of mica-schist pebbles from the Eocene conglomerates of the Tylicz and Krynica Zone (Magura Nappe, Outer Flysch Carpathians)

Geologica Carpathica, 2016
During the Łate Cretaceous to Palaeogene, the Magura Basin was supplied by clastic material from source areas situated on the northern and southern margins of the basin, which do not outcrop on the surface at present.

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.

Variscan Plutonism in the Geodynamic Evolution of the Central Iberian Zone of Portugal: Castelo Branco Pluton as Another Piece of the Puzzle

Geosciences
A multidisciplinary analysis of the Pennsylvanian Castelo Branco pluton of Central Iberian Zone (Iberian Variscan belt) was made, focusing on its magnetic behavior and fabric, microstructures, microfractures, and radiometric and gravimetric anomalies ...

Antimony deposits in the Variscan Armorican belt, a link with mafic intrusives?

, 2016
International audienceThe Variscan Armorican belt was the World leading producerof antimony at the beginning of the twentieth century. However,geological controls on the deposits remain unconstrained.Here, we illustrate the field setting ...

Mississippian synorogenic sedimentation in the Variscan belt: Why are NW and SW Iberia flysch basins so different and yet so similar? [PDF]

, 2023
Devonian-Carboniferous synorogenic sedimentation is described across the Variscan orogen, as well-preserved exposures in late orogenic structures between continental blocks. Variscan marine sedimentary sequences are described in both colliding continents:
