Structural map of Variscan northern Sardinia (Italy)

In this paper, we present the geological structural map (1:100.000 scale, about 2300 km2 of total 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. A set of 10 samples of granitic rocks collected from different plutons were characterized for their crystallization age. This provided an accurate timing of magmatic events related to the development of the Corsica-Sardinia Batholith. The structural map complemented with the results of geochronology might represent a benchmark for future studies on Variscan geodynamics.
