Anatomie et physiologie d'un prisme d'accretion; premiers resultats des forages du complexe de la ride de la Barbade, Leg ODP 110

During the Ocean Drilling Program Leg 110, six sites, on the lower eastern slope of the Barbados ridge accretionary complex and in front of it on the Atlantic Abyssal Plain, were drilled. These sites permitted the analysis of Eocene to Present sedimentation, and the structures and fabrics induced by offscraping and overthrusting of a part of the sedimentary series that covers thb oceanic floor. The main, basal, décollement, as well as several thrust-faults and asymmetrical to isoclinal folds were intersected. Chemical studies of pore water demonstrates that thrust-fault planes and the décollement are preferential pathways for dewatering processes and associated fluid circulation
