Role of extension and compression in the evolution of the eastem margin of Iberia: the ESCI- València Trough seismic profile

Carlos.Santisteban@uv.es The ESCI-València Trough deep seismic reflection profile crosses the eastern margin of Iberia and can be divided into three regions according to crustal structure. From NW to SE they are: a) the Ebro Basin, whit a 33 km thick continental crust wich remained almost undeformed during the Cenozoic and is very reflective in its lower part; b) the Continental Margin, made up of the Catalan-Valencian Domain and the Balearic Promontory with a thin (12 to 30 km thick) continental crust wich was deformed during the Cenozoic, extensional structures predominating the first domain and contractional structures in the second; and c) the Algerian Basin, with a 9 km thick oceanic c…
