Figure F5. Multichannel seismic reflection profiles across thinned continental crust of the western Galicia margin, adapted from Tucholke et al. (2007). Profile locations are shown on the inset map together with bathymetric contours in meters. Seismic sequences are as follows: 6 = Berriasian, Tithonian, and older sediments and basement; 5 = Valanginian to Hauterivian; 4 = Barremian to Aptian; 3 = Albian and younger. This numbering follows the conventions of Mauffret and Montadert (1988). The Aptian event is approximately at the Aptian/Albian boundary. In panels A and B, the S reflection is interpreted to be a detachment surface between continental crust and underlying mantle (e.g., Reston, 1996). Bold arrows show fault slip, and light arrows highlight sedimentary onlap.
