Microstructural Investigation of Variscan Late-Collisional Granitoids (Asinara Island, NW Sardinia, Italy): New Insights on the Relationship Between Regional Deformation and Magma Emplacement

open access: yesGeosciences
In the framework of the geological mapping of sheet “n. 425—Asinara Island” (NW Sardinia, Italy) of the Italian National Geological Mapping Project (CARG Project), three late- to post-collisional Variscan intrusive units are recognized: (i) Castellaccio ...

Late Palaeozoic tectonics in Central Mediterranean: a reappraisal

open access: yesSwiss Journal of Geosciences, 2020
A revision of late Palaeozoic tectonics recorded in Tuscany, Calabria and Corsica is here presented. We propose that, in Tuscany, upper Carboniferous-Permian shallow-marine to continental sedimentary basins, characterized by unconformities and abrupt ...

Ordovician tectonics of the South European Variscan Realm: new insights from Sardinia

open access: yesInternational Journal of Earth Sciences, 2022
AbstractAlthough much is known about the Ordovician tectonics of the South European Variscides, aspects of their geodynamic evolution and palaeogeographic reconstruction remain uncertain. In Sardinia, Variscan tectonic units include significant vestiges of Ordovician evolution, such as a fold system that affected only the Cambrian–Lower Ordovician ...

From Compression to Extension in the Eastern Pyrenees: New Insights From Low‐Temperature Thermochronology

open access: yesTectonics, Volume 45, Issue 1, January 2026.
Abstract The tectonic evolution of the Eastern Pyrenees from the orogenic mountain building to the post‐orogenic dismantling is still debated. Since the Oligocene, the Gulf of Lion rifting in the Western Mediterranean superimposed crustal extension in this eastern part of the Pyrenean belt, while compressional tectonics persisted in the Central ...

U-Pb zircon age of Ordovician magmatism in the Albera Massif (Eastern Pyrenees) [PDF]

open access: yes, 2011
New geochronological data from the Albera Massif confirm the presence of an Early - Mid Ordovician igneous event (472 - 465Ma) recorded in the pre-Variscan rocks of the Pyrenees.

Coupling Phase Equilibrium Modelling and Apatite‐in‐Garnet Elastic Barometry to Unravel the P–T Path of the Micaschist Unit From the Zicavo Metamorphic Complex (Corsica, France)

open access: yesJournal of Metamorphic Geology, Volume 43, Issue 7, Page 681-705, September 2025.
ABSTRACT To gain insights into the pressure–temperature evolution of a scarcely studied portion of the Variscan basement of Corsica in southern Europe, we combined phase equilibrium modelling, Zr‐in‐rutile thermometry and apatite‐in‐garnet elastic barometry. We investigated Grt‐St micaschist rocks containing garnet grains of several millimetres in size

The Permo‐Carboniferous Basins of the Catalan Pyrenees (NE Iberia): An Example of Interacting Tectonics and Collapse Calderas

open access: yesTectonics, Volume 44, Issue 7, July 2025.
Abstract The Permo‐Carboniferous terrains of the Catalan Pyrenees show evidence of extensive calc‐alkaline orogenic volcanism with predominant pyroclastic deposits of dacitic to rhyodacitic composition. These Permo‐Carboniferous basins have been interpreted as volcano‐tectonic depressions associated with a transtensional regime following the Variscan ...

The first isotopic evidence of Early Iron Age lead ore exploitation in the Silesian‐Krakow upland, Poland: a provenance study of Lusatian culture lead ornaments

open access: yesArchaeometry, Volume 67, Issue 3, Page 552-569, June 2025.
Abstract The Bronze and Early Iron Ages witnessed a significant increase in trade relations driven by the search for valuable metals. This paper presents new insights into the use of galena from the Silesia and Krakow Upland region in southern Poland, known as the ‘Olkusz ore deposits’, within the context of metal ores in prehistoric Europe.

On the crustal composition of the Sardinia–Corsica continental block inferred from receiver functions [PDF]

open access: yesSolid Earth
Subduction-related geodynamic processes significantly influence plate tectonics and Earth's evolution, yet their impact on the continental crust remains poorly understood.
