摘要: The Variscan section exposed across north Sardinia consists of migmatitic complexes intruded by the huge Corsica-Sardinia Batholith (CSB). This latter represents one largest magmatic provinces assembled in Late times, between about 340 and 280 Ma. composition most plutons ranges from monzogranitic to granodioritic, with subordinate gabbro-dioritic terms leucocratic, muscovite ±cordierite ± garnet-bearing, peraluminous granites. compositional homogeneity often makes geological mapping a difficult task, unless large geochemical, geochronological isotopic datasets areavailable. In this work we present new structural map northern Sardinia. results are based on detailed field-structural survey, U-Pb zircon dating extensive, situ, geochemical characterization aportable gamma ray spectrometer.
