“…These data are correlated with published information from the Lusitanian Basin [Wilson et al, 1989;Hiscott et al, 1990a;Alves et al, 2002Alves et al, , 2003b, the Porto Basin (C. Moita et al, Porto Basin: Seismic interpretation report, unpublished report, MILUPOBAS project, 1996), the Iberia Abyssal Plain ] and the Newfoundland -central eastern North American margin [Tankard and Welsink, 1987;Tankard et al, 1989;Withjack et al, 1998;Shipboard Scientific Party, 2004].

Diachronous evolution of Late Jurassic–Cretaceous continental rifting in the northeast Atlantic (west Iberian margin)

et al. 2009

Regional (2‐D) seismic reflection profiles, outcrop, and borehole data are used to characterize the evolution of deep offshore sedimentary basins in southwest Iberia (Alentejo Basin). The interpreted data indicate the bulk of Late Jurassic–earliest Cretaceous subsidence occurred in the present‐day continental slope area, as shown by (1) significant thickening of synrift strata basinward from a slope‐bounding fault system (SFS), west of which the total thickness of sediment can reach more than 9.0 km, and (2) relatively thin Mesozoic strata east of the SFS, where thickening of synrift units against principal faults is limited. Five principal regressive events and their basal unconformities reflect tectonic uplift and relative emersion in proximal basins, which were located on the rift shoulder to subsiding tilt blocks west of the SFS. These regressive events are correlated with major rift‐related events occurring on the deeper margin. Direct comparisons with the Peniche Basin of northwest Iberia reveal that significant portions of the Iberian lower plate margin were uplifted and eroded during the last stages of continental rifting. This process was repeated at different times (and in different areas) as the locus of rifting and continental breakup migrated northward. As a result, two distinct rift axes are recognized in west Iberia, a first axis extending from the Porto Basin to the Alentejo Basin and a second axis located on the outer proximal margin north of 38°30N. In addition, the SFS delimited (1) prograding deposits of Cretaceous‐Paleogene age and (2) late Cenozoic deposits draping the modern continental slope. These latter facts demonstrate that on lower plate passive margins, the relative position of the continental slope is established during the final rifting episode(s) preceding continental breakup.

Field work in the South-Central Pyrenees suggests that omission contacts (i.e. younger over older rocks) occur at the base of the Cadí unit (Cadí thrust), and pass laterally into thrusts. This change occurs across tear faults which are present in the hangingwall of the Cadí thrust sheet and which controlled the deposition of Upper Cretaceous sediments (Adraén formation). Detailed mapping in the contact area between the Nogueres and Cadí units has shown that the actual thrust geometry in the study area is controlled by preexisting normal and transfer faults which developed in an already compressional context. Lateral ramps or tear faults develop depending on the angle between the pre-existing extensional transfer fault and the thrust transport direction.

“…The Jeanne d'Arc Basin offshore Newfoundland is one of numerous half-graben structures on the continental margin of eastern Canada that are associated with rifting between the Grand Banks and the Iberian Peninsula during the early opening stages of North Atlantic from Late Triassic to Early Cretaceous (Tankard and Welsink, 1988). The relatively narrow (40-90 km wide and 200 km long) fault-bounded northward plunging basin is filled with up to 20 km of post-Paleozoic sediment.…”
