Control of mantle dynamics on Iberian and Mediterranean basins
Supervisor:
Yves Lagabrielle – Université de Rennes
Major Results
A detailed field study was conducted on exceptionally preserved Cretaceous distal margin analogs in two key areas of the western Pyrenees (North Pyrenean Zone): the Urdach and Saraillé ultramafic massifs in the Chaînons Béarnais range The importance of the crustal structure inherited from previous Paleozoic and Mesozoic tectonic events is highlighted and it is interpreted that mantle exhumation was partially achieved before the Cretaceous North Pyrenean rifting.
