Abstract

 Two seismic refraction models with coincident multichannel seismic reflection profiles allow us to obtain a detailed interpretation of the velocity structures across the margin. This comprehensive dataset provides (1) the delineation of the major crustal domains in the study area, which is continental onland; (2) P-wave velocities and major geological interfaces down to the Moho; and (3) the along-strike variations of the deep structures and indications of magmatism. 

The interpretation of these seismic refraction models is related to the publication of  Watremez et al. (in rev) Tectonics
