The conjugate margins system of the Gulf of Lion and West Sardinia (GLWS) represents a unique natural laboratory for addressing fundamental questions about rifting due to its landlocked situation, its youth, its thick sedimentary layers, including prominent palaeo-marker such as the MSC event, and the amount of available data and multidisciplinary studies. The main goals of the SARDINIA experiment, were to (i) investigate the deep structure of the entire system within the two conjugate margins: the Gulf of Lion and West Sardinia, (ii) characterize the nature of the crust, and (iii) define the geometry of the basin and provide important constrains on its genesis. This paper presents the results of P-wave velocity modelling on three coincident near-vertical...

Étude géologique et géophysique des marges continentales passives : exemple du Zaïre et de l'Angola

Autores: Moulin, Maryline.
The objective of the present work is to study the formation of the passive continental margins of the Central Segment of the South Atlantic, most particularly the Congo and Angola margins. We propose a combined approach, which integrates structural constraints based on geological cross-sections (based on seismic data) and global constraints based on plate kinematic reconstructions.  The structural study is based on : i) MCS and refraction data collected during the ZaiAngo programme (a joint project conducted by Ifremer and Total) ; ii) proprietary, industrial seismic data (courtesy of Total) from the Angola margin and iii) on all available seismic lines from the Africa and Brazil conjugated margins, between Walvis Ridge and the Equatorial Fracture Zones....
