This recent monograph, focusing on the Portuguese shelf and slope, written in French and published in Lisbon, might easily be overlooked and this would be unfortunate. The value of this study, in my view, is that it couples two distinct approaches: submarine geomorphology emphasizing detailed descriptions of the seafloor surface and interpretation of bathymetric features (JR Vanney's contribution), and the relation of these features to sedimentary and eustatic processes and to subsurface structure (D. Mougenot's contribution). The nature of the assembled data and their origin are diverse; material was collected on several cruises involving moderately to closely-spaced grid bathymetric and seismic surveys. The study correlates land forms on Portugal with adjacent submerged terrains of the coast, inner to outer shelf and slope. The study is an excellent in-depth summary of a passive-type margin. The Portuguese shelf width, which ranges from 10 to 65 km, is narrower than that of many passive margins. The authors divided the Portuguese margin into eight regions (from north to south): Porto, Figueira da Foz, Nazar~, Peniche, Lisbon, Sines, Portimao and Faro. For each sector, a detailed bathymetric chart and interpreted geomorphologic map were prepared. Each chart is accompanied by selected seismic profiles (0.2 to 1.0 second penetration) and interpreted stratigraphicstructural sections. Probably the most interesting, and in some cases spectacular, documents are the block diagrams depicting the morphology of different shelf sectors. Also valuable are a series of structural cross sections showing the geological evolution from the Permian-Triassic to the Pliocene-Quaternary. These latter cross-section reconstructions indicate how the Meseta Iberian basement, subdivided and broken by a series of Late Hercynian fractures, has been affected by movements related to the Atlantic opening and the Mesogean closure. It is this basement which, to a considerable extent, controls the present seabed configuration. The study also provides a comparative analysis of the submarine realm and adjacent subaerially-exposed morphologies. Three major seabed types are identified: an essentially depositional type (emphasizes the deltas off the Tejo and Sardo Rivers, progradational series, canyons, etc.); a structural type [fault-scarps, eruptive (volcanic) and tectonic dams, etc.]; and a planed-form type produced by erosion of deformed seafloor surfaces. The evolution of the margin involves three major phases: Late Hercynian events which resulted in a thinning of the continental crust, Triassic to Upper Cretaceous extensional phases, and Late Cretaceous to recent compressive phases related to the movement of Africa toward southeastern Europe. Although this booklet may not be an essential volume for every marine geologist's bookshelf, it is nevertheless a valuable document for any specialist working on passive margins and, specifically, the European-Eastern Atlantic shelves. Moreover, it should not be overlooked by those interested in the application of a refreshing, multidisciplinary approach to the integration and interpretation of a land-shelf-slope system.
