Figure F6. Multichannel seismic reflection profile showing strong Aptian event reflection (arrows) that merges with the surface of a peridotite ridge on the western Galicia margin (adapted from Tucholke et al., 2007). Map shows location, with bathymetric contours in meters. Note that the strong Aptian event reflection masks underlying basement structure near the peridotite ridge. The reflection amplitude decreases with distance from the ridge, suggesting that weak serpentinites on the ridge provide a source of coarse debris.
