HTLP metamorphism and fluid‐fluxed melting during multistage anatexis of continental crust (N Sardinia, Italy) [PDF]

Journal of Metamorphic Geology, Volume 41, Issue 1, Page 25-57, January 2023., 2023
Abstract The Variscan high‐grade metamorphic basement of northern Sardinia and southern Corsica record lower Carboniferous anatexis related to post‐collisional decompression of the orogen. Migmatites exposed in the Punta Bianca locality (Italy) consist of quartz + biotite + plagioclase + K‐feldspar orthogneisses, garnet and cordierite‐bearing diatexite

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

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

Evolution of the Corsica–Sardinia Batholith and late-orogenic shearing of the Variscides

Tectonophysics, 2015
The Corsica–Sardinia Batholith formed in the late Carboniferous–Permian along the northern Gondwana margin. One or more of the following processes may have raised the Variscan geotherm enhancing melting of the crust and uppermost mantle, such as: i) break-off and detachment of the Rheic oceanic slab, ii) mantle delamination due to gravitational re ...

Structure of a Variscan migmatite-granite transition zone (N Sardinia, Italy)

Journal of Maps, 2023
This paper presents the structural map of the Barrabisa Complex, an E-W ribbon-like migmatitic massif exposed in the northern part of Sardinia. The migmatites consist of metatexites and diatexites with variable melt proportion, grading in the central ...

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) [PDF]

Journal 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

Paleomagnetic Evidence for Pre‐21 Ma Independent Drift of South Sardinia From North Sardinia‐Corsica: “Greater Iberia” Versus Europe

Tectonics, Volume 42, Issue 5, May 2023., 2023
Abstract It is unanimously acknowledged that the Corsica‐Sardinia microplate rotated counterclockwise (CCW) by 40–50° between 21 and 15 Ma, synchronous with Liguro‐Provençal Basin oceanic spreading. Conversely, 60–120° CCW rotations with respect to Europe from Sardinia (Permian dykes, volcanics and sediments, Mesozoic carbonates, and lower Eocene ...

Geophysical‐Petrological Model for Bidirectional Mantle Delamination of the Adria Microplate Beneath the Northern Apennines and Dinarides Orogenic Systems

Journal of Geophysical Research: Solid Earth, Volume 127, Issue 12, December 2022., 2022
Abstract This study presents a geophysical‐geochemical integrated model of the thermochemical structure of the lithosphere and uppermost mantle along a transect from the Northern Tyrrhenian Sea to the Pannonian Basin, crossing the northern Apennines, the Adriatic Sea, and the Dinarides fold‐thrust belt.

Geology of late-Variscan Sàrrabus pluton (south-eastern Sardinia, Italy) [PDF]

, 2021
This paper deals with the geological mapping of the late-Variscan Sarrabus pluton, (south-eastern Sardinia), a shallow multiple and composite igneous complex dominated by several generations of granodiorites, metaluminous and peraluminous granites and ...

Late Palaeozoic tectonics in Central Mediterranean: a reappraisal [PDF]

, 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 ...
