“…The stratigraphic record starts with Triassic continental sedimentary deposits marking the rifting start, and ends on top of the Cenozoic sedimentary rocks, that are still exposed to marine water-rock interface weathering. We also find a Triassic-Jurassic salt unit and different marine sedimentary megasequences, all slightly to locally highly deformed by the Alpine Orogeny and the salt tectonics (Alves et al 2006). The salt formation is the main barrier in the area to an accurate seismic imaging and interpretation.…”

SUMMARYA gravimetric study has been carried out over a sector of the West Iberian Margin (WIM), constrained by well and seismic data. The analytic development was made through three main stages: the processing of different gravity datasets, the production of gravity anomaly maps and 2,5D models using the processed data, and the geophysical interpretation of maps and models. The final results of the interpretation achieved, allowed the determination of crustal structure and its variation/complexity along the WIM. The main obtained results concern the pre-saline infilling and the deep structure of the margin, which vary related to the location of first-order oblique fractures.

“…The margin evolved through a sequence of rift episodes, between the Late Triassic and Early Cretaceous, and the structure of its marginal basins is strongly controlled by prominent Variscan lineaments, mainly inherited from a late Carboniferous-early Permian phase of variscan strike-slip deformation (RIBEIRO et al, 1979;PINHEIRO et al, 1996). These lineaments include the NNE-SSW and NNW-SSE to NW-SE listric and/or planar normal faults and NE-SW to ENE-WSW transverse faults, which delimit the main depositional systems identified along the margin (WILSON et al, 1989;MURILLAS et al, 1990;PINHEIRO et al, 1996;ALVES et al, 2006). During the Alpine compression, from the late Cretaceous onwards, some of these features were reactivated as reverse or thrust faults, sometimes with a strike-slip component (BOILLOT et al, 1979;MASSON et al, 1994).…”

“…The basin is located in the northward continuation of the Lusitanian Basin (Fig. 1), delimited to the east by the Porto-Tomar Fault, which has been active throughout most of the basin evolution (ALVES et al, 2006;CUNHA, 2008). A horst block on its western side separates the Porto Basin from the Galicia Interior Basin (PINHEIRO et al, 1996).…”

M. C.; Cunha, T. A.; Terrinha, P.; Carneiro, J.; Ribeiro, C. Abstract -The storage of CO 2 is an up to date topic involving numerous governmental, academic and commercial institutions. COMET is a joint research project co-financed by the European Seventh Framework Programme that aims at identifying and assessing the most cost effective CO 2 transport and storage infrastructure able to serve the West Mediterranean area, namely Portugal, Spain and Morocco. In this project a preliminary assessment of the potential reservoir and storage capacity in the Porto Basin was made. To be considered geological units for potential storage of CO 2 certain geological criteria must be obeyed, including depth, porosity, and permeability, among others. Through the analysis of simplified porosity-depth profiles, two formations were identified as potential reservoirs for CO 2 storage: the Torres Vedras and Silves formations. In the Porto Basin, between the recommended depths, the maximum porous volume available for storage was estimated to be 2364 km 3 for the Torres Vedras Formation and 334 km 3 for the Grés Silves Formation.

“…The basin started to open in the Late Triassic and is partitioned into a northern (NLB), central (CLB), and southern (SLB) sector by two reactivated Varis− can major faults, i.e., the Nazaré and Tagus faults. Triggered by rapid rifting during the Late Jurassic, the basin began to differentiate into several subbasins, which developed as a re− sult of diapirism that led to the formation of salt diapirs pre− dominantly along lineaments of Variscan origin (Alves et al 2002(Alves et al , 2006Carvalho et al 2005). Today, the Lusitanian Basin is filled with sediments of Late Triassic to Pleistocene age.…”

Taxonomy and biostratigraphy of the Late AlbianActinoceramus sulcatuslineage (Early Cretaceous Bivalvia, Inoceramidae)

TheActinoceramus sulcatuslineage (Parkinson, 1819) (Bivalvia: Inoceramidae) is a very distinctive and abundant component of late Albian (Early Cretaceous) molluscan assemblages that is found throughout Europe, Central Asia, Japan and the Far East of Russia, southern and western North America, South Africa, and possibly India, in a range of shallow- to deep-marine facies. The lineage encompasses a wide and continuous range of morphologies that provide evidence of phyletic evolution at varying rates combined with large ecophenotypic plasticity within populations. The evolution ofA. sulcatusmarks the oldest appearance of well-developed radial folds and sulci within the Inoceramidae. The range of morphological variation makes formal taxonomic subdivision of the group problematic. Here we use a combination of formal successional subspecies and informal morphotypes to subdivide the lineage into the following taxa:A. sulcatusformasulcatus, A. sulcatusformasubsulcatus(Wiltshire, 1869),A. sulcatusformamunsoni(Cragin, 1894), andA. sulcatus biometricusCrampton, 1996. Within these taxa and morphotypes, we synonymise a large number of earlier names that have been applied to variants within the lineage. Each of the forms recognized has biostratigraphic utility and we describe four new lineage biozones, in ascending order:A. concentricus parabolicus, A. sulcatus, A. sulcatusformamunsoni, andA. sulcatus biometricusbiozones. The lowest occurrence ofA. sulcatusis approximately coincident with the base of the upper Albian as currently defined, at least throughout most of Europe, and this datum provides a valuable tool in correlation. The nature of radial folds within theA. sulcatuslineage poses interesting but still unanswered questions regarding shell morphogenesis in bivalves and the functional significance (if any) of radial folds in the Inoceramidae.
