Geological map of Corsica and Sardinia

Geological map of Corsica and Sardinia

The originality of this Corso-Sardinian synthesis is to present the formations according to their chronology - as for the classic geological maps - but also according to the geodynamic context in which they were formed or are observed. Thus, the following have been distinguished:

1- for the Hercynian chain, the classic division into a) inner zone, b) nappes zone and c) outer zones and linking magmatism to the post-collisional extension of the chain;

2- the autochthonous cover of the South European continental margin;

3- the Balano-Ligurian and Ligurian-Piedmontese oceanic domain with continental influence;

4- the collisional chain of alpine Corsica, with in particular the eclogitic belt;

5- the complexes (in relation to the Apennines) linked to the opening of the Liguro-Provençal basin, the northern and then the southern Thyrrenian Sea.
