Geothermobarometry on anatectic melts – a high-pressure Variscan migmatite from northeast Sardinia
International Geology Review, 2013We studied a high-pressure amphibole-bearing migmatite cropping out along the northeastern coast of Sardinia, a few kilometres northeast of Olbia, in order to improve our knowledge about its evolution using pressure–temperature (P–T) pseudosections. Thermodynamic calculations with PERPLE_X were undertaken in the system Na2O–K2O–CaO–FeO–MnO–MgO–Al2O3 ...

Variscan metamorphism in Sardinia, Italy: review and discussion
Journal of the Virtual Explorer, 2005The Sardinian segment of the Variscan chain is divided into four tectono-metamorphic zones from NE to SW: 1) Inner zone, with medium- to high-grade metamorphic rocks and migmatites; 2) Internal Nappe zone, with low- to medium-grade rocks; 3) External Nappe zone, with low-grade metamorphic rocks; 4) External zone, with very low- to low-grade rocks ...

Excursion in the Variscan Basement of Northern Sardinia (Italy): Field Guide
Journal of the Virtual Explorer, 2006The 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.

Corsica and Sardinia in the Variscan Chain
1994Corsica and Sardinia are two islands which separate the Western Mediterranean Sea into the Provencal Basin in the West and the Tyrrhenian Sea in the East (Fig. 1). Paleomagnetic, structural, and lithological similarities indicate that Corsica and Sardinia can be correlated with the Provence basement in southeastern France (Arthaud and Matte 1966 ...

From thickening to extension in the Variscan belt — kinematic evidence from Sardinia (Italy)
Terra Nova, 1999The Variscan nappe stack of SE Sardinia originated as a result of several stages of nappe imbrication during the Lower Carboniferous phases of the Variscan orogeny. The crustal shortening caused regional SSW‐and W‐directed thrusting, greenschist facies metamorphism and open‐to‐isoclinal polyphase folding.

High-temperature albitites from late-Variscan Sàrrabus pluton (SE Sardinia, Italy)
2022Uncommon high-temperature Na-metasomatized rocks close to sodic fenites are hosted in coeval granodiorites from the late-Variscan (286 ± 2 Ma) Sàrrabus pluton (SE Sardinia). They show sharp contacts with the host rocks and consist of small, irregular lenses of “spotted” rocks and hectometric layered, albititic bodies, scattered along a 15 km-long WNW ...

Structural map of Variscan north Sardinia
2013The Variscan section exposed across north Sardinia consists of migmatitic complexes intruded by the huge Corsica-Sardinia Batholith (CSB). This latter represents one of the largest magmatic provinces assembled in Late Variscan times, between about 340 and 280 Ma.
