Figure AF2. Sparker seismic reflection profile (Line FADO L-38) across the Faro-Albufeira drift on the middle slope showing location of proposed Site GC-01A. Four major low-resolution depositional sequences have been recognized in the Pliocene and Quaternary sedimentary record (Llave et al., 2001; Hernández-Molina et al., 2002, 2006) and are separated by four relevant discontinuities: LPR (early Pliocene?), QBD (base of the Quaternary?), and MPR (mid-Pleistocene?). LPR erosive discontinuity could represent the onset of drift formation.
