Metamorphic Remnants of the Variscan Orogeny across the Alps and Their Tectonic Significance
Geosciences, 2023 Lithospheric slices preserving pre-Alpine metamorphic imprints are widely described in the Alps. The Variscan parageneses recorded in continental, oceanic, and mantle rocks suggest a heterogeneous metamorphic evolution across the Alpine domains.

Geochemical and geochronological dataset of rutile from a Variscan metabasite in Sardinia, Italy [PDF]
Data in Brief, 2020 A c. 500 m wide and 1.5 km long body consisting of basic to ultrabasic rocks, metamorphosed up to granulite-facies and retrogressed to amphibolite-facies conditions during the Variscan orogeny, crops out near Olbia (NE Sardinia, Italy).

Together but separate: decoupled Variscan (late Carboniferous) and Alpine (Late Cretaceous–Paleogene) inversion tectonics in NW Poland [PDF]
Solid Earth, 2022 In Europe, formation of the Palaeozoic Variscan orogenic belt, and the Mesozoic–Cenozoic Alpine–Carpathian orogenic belt led to a widespread inversion events within forelands of both orogenic domains.

The enigmatic curvature of Central Iberia and its puzzling kinematics [PDF]
Solid Earth, 2020 The collision between Gondwana and Laurussia that formed the latest supercontinent, Pangea, occurred during Devonian to early Permian times and resulted in a large-scale orogeny that today transects Europe, northwest Africa, and eastern North America ...

The Volcanic History of the UNESCO Global Geopark Bohemian Paradise [PDF]
Geoconservation Research, 2023 Central Europe and the area of the UNESCO Global Geopark Bohemian Paradise have been affected by global tectonic events, especially during the last 500 million years. Volcanic phenomena are the most striking traces today of such past tectonic events.

Geology of the Montigiu Nieddu metamorphic basement, NE Sardinia (Italy)
Journal of Maps, 2020 A geological map at 1:10,000 scale is presented that shows the distribution of the metamorphic rock units in the area of Montigiu (Mt.) Nieddu (NE Sardinia). These units belong to the High-Grade Metamorphic Complex in the Inner Zone of the Variscan chain
