Multichannel seismic image of the crustal thinning at the NE Iberian Margin combining normal and wide angle reflection data

The seismic image of the Moho at the transition from the NE Iberian Peninsula to the Western Mediterranean Sea is investigated using coincident steep and wide‐angle reflection data merged into a single stacked and migrated section. The multichannel analysis of onshore/offshore large‐aperture data provides new insight on the deep structure in areas where the steep sections lack penetration, and reveals that the crust undergoes a strong but continuous thinning along the flanks of the Valencia trough. The combined seismic image indicates that almost half of the continental crust (14–15 km) is lost in less than 60 km horizontal distance.This work has been partially financebdy CICYT projectnsø G EO89-0858-GE;E O90-0733 and PB86-0619Peer reviewe
