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

Ano: 2003 URL: http://archimer.ifremer.fr/doc/2003/these-82.pdf A new starting point for the history of the central Atlantic ArchiMer Sahabi, Mohamed; Aslanian, Daniel; Olivet, Jean-louis. A new starting point for the history of the central Atlantic. The first oceanic crust in the central Atlantic is usually thought to have a Middle Jurassic age. The new interpretation of the two key parameters, the African homologue of the East Coast Magnetic Anomaly and the situation of the Triassic salt basin of Morocco and Novia Scotia, shows that this age was underestimated by about 20 Ma. In our kinematic reconstruction, the first oceanic crust begins at the Late Sinemurian. This difference in age is crucial for the evolution of those margins and we discuss here its consequences.

Ano: 2004 URL: http://archimer.ifremer.fr/doc/2004/publication-437.pdf Un modèle général de d'évolution de l'océan indien ArchiMer Sahabi, Mohamed. The last global synthesis of the evolution of the Indian ocean which satisfactorily describes the kinematics of the five major plates, up to the initial stages, dates back to Norton and Sclater [1979]. Although the most recent phases of evolution have been largely detailed, in particular in the proximity of the triple junction, the initial stages of evolution have been generally described by models quite speculative and generally only constrained by pairs of plates. The recentmost gravity data based on the altimetric satellites SEASAT, GEOSAT and ERS1 [Sandwell and Smith, 1992] give an homogenoeus image of sea-floor topography. These data, declassified to the south of 30°S, reveal previously unknowkn features of the sea-floor fabric and allow to further...
