Beyond the Axial Zone: Unveiling the Regional Mylonitic Complex in the Variscan Sardinian Basement

Sardinia (Italy) represents one of the most comprehensive cross-sections of the Variscan orogen, characterised by its structurally and metamorphically complex axial zone, which still presents significant unresolved questions. This study integrates newly acquired field data with an extensive re-evaluation of previously published geological datasets from

40Ar-39Ar dating of the Inner Carpathians Variscan basement and Alpine mylonitic overprinting

Tectonophysics, 1993
Abstract The 40Ar-39Ar dating method has been applied to mylonitic rocks from the Carpathian mountains. These are Variscan metamorphic and magmatic rocks that were overprinted during the Alpine orogeny. The Inner Western Carpathians are conventionally described as a nappe pile formed by northward movement and then subjected to intense strike-slip and

Age determination of Ordovician magmatism in NE Sardinia and its bearing on Variscan basement evolution

Journal of the Geological Society, 2005
A newly discovered pre-Variscan cover–basement relationship in NE Sardinia is defined by differences in structural and metamorphic histories. The oldest metamorphic fabrics in the basement are absent from a series of metaplutons that are inferred to be comagmatic with metavolcanic rocks in the cover.

Excursion in the Variscan Basement of Northern Sardinia (Italy): Field Guide

Journal of the Virtual Explorer, 2006
The Variscan basement in Sardinia is an almost complete section across the South Variscan belt showing the transition from the low- up to the medium-high-grade basement ( Figure 1 ). The basement shows beautiful expositions of folded, sheared and metamorphosed Paleozoic rocks poorly affected by Alpine tectonics.

Tibetan, Variscan, and Precambrian Basement Reactivation: Products of Continental Collision

The Journal of Geology, 1973
Extensive terranes of basement reactivation are interpreted as resulting from crustal thickening following continental collision. It is suggested that terranes, such as the Grenville Province and much of the Variscan orogenic belt in Europe, have their modern analog in the Tibetan Plateau. The Tibetan Plateau is underlain by a continental crust between

Late Variscan Magmatic Evolution of the Alpine Basement

1993
After having experienced the Variscan orogenic episodes, the pre-Mesozoic Alpine basement was subjected to large-scale shearing effects accompanying lithosphere distensional thinning, “Basin and Range”-like tectonics and high geothermal regimes. As a result of intrusion of mantle-derived magmas and induced crustal anatexis, almost all pieces of ...

Superposed Variscan and Alpine Deformation in the Basement Rocks of Southern Andorra, Central Pyrenees

Journal of the Geological Society, 2023
Detailed mapping, structural analysis and cross-section constructions yield new data on the geometry and chronology of Variscan and Alpine deformations in the central Pyrenees of southern Andorra. The study area is characterized by polyphase deformation and strain partitioning owing to the presence of an efficient décollement level within ...
