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

Geosciences
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 ...

Geothermal Heat Flow Mapping of Germany Integrating Multi‐Geophysical and Geological Constraints With Uncertainty Quantification

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 10, October 2025.
Abstract Geothermal heat flow (GHF) is a critical parameter for understanding the thermal structure and dynamics of the lithosphere, providing critical insights into lithospheric thermal evolution and geothermal energy potential. This study investigates the spatial variability of GHF in Germany by applying a Bayesian Markov Chain Monte Carlo method to ...

Late Variscan magmatism in the Nevado-Filábride Complex: U-Pb geochronologic evidence for the pre-Mesozoic nature of the deepest Betic complex (SE Spain)

Lithos, 2012
Abstract Orthogneisses crop out in different lithostratigraphic positions throughout the Nevado-Filabride metamorphic Complex (Betic Cordillera, southern Spain). Their abundance offers the opportunity to establish its origin and to date the ages of acid magmatism and of early deposition ages of metasedimentary host rocks of the orthogneisses, in this

Tracking Bronze Age ‘itinerant smiths’ in western Poland: insights from Nd and Sr isotope data

Archaeometry, Volume 67, Issue 5, Page 1195-1211, October 2025.
Abstract The neodymium (Nd) isotope composition of stone casting moulds found in graves of Bronze Age ‘itinerant smiths’ in western Poland was analysed to determine the provenance of their raw materials. For the first time in archaeological research, the Nd model age (TDM)—a highly useful parameter in studying the provenance of geological materials—has

The Uplift of Armorica and the Bretonian Movements of the Variscan Orogeny‐New Insights From Detrital Zircons in the Early Carboniferous Terrigenous Rocks of the Laval Basin (Armorican Massif, France)

Geochemistry, Geophysics, Geosystems
In the French Armorican Massif, the Bretonian phase of the Variscan orogeny has been defined by the Late Devonian (Famennian‐Frasnian) erosion gap, and the Early Carboniferous (Tournaisian) syntectonic terrigenous deposits of the l’Huisserie formation in

New LA-ICP-MS U-Pb zircon dating for Strandja granitoids (SE Bulgaria): evidence for two-stage late Variscan magmatism in the internal Balkanides

TURKISH JOURNAL OF EARTH SCIENCES, 2015
The Strandja Massif (Sakar-Strandja Zone) forms an important link between the Balkan Zone (external Balkanides) of Bulgaria, which is commonly correlated with the Variscan orogen in Central Europe, and the Western Pontides of Turkey. The Bulgarian part of the massif is composed of a metamorphic basement (various granite gneisses, paragneisses, and ...

Late magmatic controls on the origin of schorlitic and foititic tourmalines from late-Variscan peraluminous granites of the Arbus pluton (SW Sardinia, Italy): Crystal-chemical study and petrological constraints

Lithos, 2018
Tourmalines from the late-Variscan Arbus pluton (SW Sardinia) and its metamorphic aureole were structurally and chemically characterized by single-crystal X-ray diffraction, electron and nuclear microprobe analysis, Mössbauer, infrared and optical absorption spectroscopy, to elucidate their origin and relationships with the magmatic evolution during ...
