Figure F5. Simplified model (after Krawczyk et al., 1996) to account for the dispersion of sites with Jurassic clastic sediments (Fig. F3) by extension of the lithosphere through detachment faulting during rifting of the southern Iberia Abyssal Plain margin. A. In a first phase of rifting, lithospheric extension may have been accommodated by detachment faulting. B. Block-faulting subsequently cuts the upper plate into tilted blocks, dismembering the detachment system and the lower plate. Sites in parentheses are offset a short distance from the three seismic reflection profiles used to create the composite section (see inset, Fig. F2).
