Metamorphic Remnants of the Variscan Orogeny across the Alps and Their Tectonic Significance [PDF]
Geosciences (Switzerland), 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.

How many subductions in the Variscan orogeny? Insights from numerical models [PDF]
Geoscience Frontiers, 2020 We developed a 2D numerical model to simulate the evolution of two superposed ocean-continent-ocean subduction cycles with opposite vergence, both followed by continental collision, aiming to better understand the evolution of the Variscan belt.

The Addition of Felsic Sediments to the Lower Continental Crust During the Variscan Orogeny
Geochemistry, Geophysics, GeosystemsLower crustal metasedimentary xenoliths (garnet‐sillimanite granulites) from the Bournac breccia pipe in the Massif Central, France, provide a robust example of sediments transported to depth and incorporated into stable lower continental crust during a ...

Variscan orogeny in Corsica: new structural and geochronological insights, and its place in the Variscan geodynamic framework [PDF]
International Journal of Earth Sciences, 2014 International audienceIn Western Corsica, remnants of pre-batholitic lithological and metamorphic assemblages are preserved as km-scale septa enclosed within Lower Carboniferous to Early Permian plutons.

Extensional perpendicular orthogonal quartz veins related to early Variscan Orogeny
Journal of Structural GeologyOrthogonal sets of veins perpendicular to the bedding occur in fold-and-thrust belts; however, the timing of their formation remains unclear in relation to orogeny. This study aims to explain the development of perpendicular orthogonal vein sets from the

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).

From Inventories to Insights: Environmental Gradients Structuring Macro‐Moths Assemblages Recorded in Nature Reserves [PDF]
Ecol EvolThe article analyses macro‐moth (Lepidoptera) inventory data from 292 nature reserves across the Czech Republic, comprising 941 species. It examines how reserve characteristics, geographic position and altitude influence species richness, community composition and their associations with species traits.

Geochemistry, Geophysics, GeosystemsIn 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
