Abstract

New detailed stratigraphical and structural surveys on Mesozoic and Cenozoic outcrops, particularly of Southwestern Sardinia, point out the presence of strong compressive (with folding and thrusting phenomena) “Alpine” tectonics, closely connected with the development of the (Laramic)-Pyrenean Chain. The new data allows us to hypothesize a different interpretation for the tectonesedimentary and magmatic evolution of the Sardinian Late Mesozoic-Paleogenic basins, considered in the evolutional Western Mediterranean context.
