Objective

Studying the continental crust of an ancient basement area: Cadomian orogeny of Northern Brittany and the Normandy-Brittany gulf. In order to reinterpret the ECORS-SWAT10 profile made in 1983, two large seismic refraction swaths were drawn perpendicularly to and along the SWAT10 profile. The expected data for the crustal velocity profile will enable better processing of the SWAT profile and provide constraints for models and hypotheses about the region's deep structure.
