Geology of late-Variscan Sàrrabus pluton (south-eastern Sardinia, Italy) [PDF]
Journal of Maps, 2021 This paper deals with the geological mapping of the late-Variscan Sàrrabus pluton, (south-eastern Sardinia), a shallow multiple and composite igneous complex dominated by several generations of granodiorites, metaluminous and peraluminous granites and ...

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).

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 ...

The variscan basement in Sardinia [PDF]
Geological Field Trips, 2015 After a short and up-to-date geological overview of the Variscan belt in Sardinia, we describe a field trip in the northeastern portion of the island that progresses from the low-grade metamorphic rocks to the Migmatite Complex and its related intrusions. The selected Stops are readily accessible and can be covered in four days.

Geosciences, 2022 The existence of pieces of the Variscan belt in the Alpine basement has been acknowledged for a long time but the correlation of these massifs to the litho-tectonic domains established in Western Europa outside the Alpine chain is still disputed.

Comptes Rendus. Géoscience, 2021 The Posada Valley amphibolites in the inner zone of Variscan Sardinia are characterized by garnet porphyroblasts containing epidote, titanite, quartz, clinopyroxene, amphibole, and plagioclase concentrated in the garnet core.

Structural map of Variscan northern Sardinia (Italy) [PDF]
Journal of Maps, 2014 In this paper, we present a geological structural map (1:100,000 scale, ∼2300 km2 surface area) of the Variscan basement of northern Sardinia. The map integrates field structural analysis, extensive gamma-ray spectrometry, and high-resolution ELA-ICP-MS U/Th-Pb zircon and monazite dating.

Uranium distribution in the Variscan Basement of Northeastern Sardinia [PDF]
Journal of Maps, 2015 We present a detailed map of uranium distribution and its uncertainties in the Variscan Basement of Northeastern Sardinia (VBNS) at a scale of 1:100,000. An area of 2100 km2 was investigated by means of 535 data points obtained from laboratory and in situ gamma-ray spectrometry measurements. These data volume corresponds to the highest sampling density
