Crustal structures of the Ligurian, Tyrrhenian and Ionian seas and adjacent onshore areas interpreted from wide - angle seismic profiles

Seas and adiacent onshore areas has been attempted with the aim of producing a general characterization and location of the different crustal typologics resulting from the data interpretation. This review with be useful for comparison and integration with the results of the deep vertical seismic profiles in the CropMare 91 project. Results are represented by crustal sections and a Moho depth contour map which outlines the following types: 1) a European continental crust under Corsica and Sardinia; 2) an Afro - Adriatic continental crust generally dipping in the direction of the Ligurian and Tyrrhenian seas; 3) an oceanic crust in the Provengal Basin and central Tyrrhenian sea; 4) an anomalous relatively thin crust which can be differentiated into Ligurian, Tuscan and peri-Tyrrhenian typologies, in places superimposed on the Afro-Adriatic crust.
