Figure 7. A. Composite profile from multichannel seismic reflection lines ALB-51A, EAS-96, and ALB-51B. B. Drawn interpretation of multichannel seismic reflection profile in (A). Reflectors and lithoseismic units I to V from Comas et al. (1992). Reflectors correspond to major unconformities within sediments: R5 = Burdigalian-Langhian, R4 = middle Miocene, R3 = early Tortonian, M = Messinian "M" unconformity (Comas, Zahn, Klaus, et al., 1996). Ia = Pleistocene, Ib and Ic = Pliocene. MB = metamorphic basement, ICR = Intracrustal reflectors. Location of seismic line is shown in Figure 2.
