| The North Fiji Basin (NFB) is a shallow oceanic basin, with depths between 2000 and 4000 m, which lies between latitude 10 degree and 25 degree South and longitude 170 degree and 180 degree East. Situated at the boundary of the Indo-Australian and Pacific plates, the NFB stands between two subduction zones of reverse polarity: the New-Hebrides subduction on its western side and the Tonga. The aim of the Seapso 3 cruise of N.O. Jean Charcot (December 1985), was to delineate the recent spreading location in the North Fiji Basin, and to observe possible associated hydrothermal manifestations. For that we first have performed a large scale bathymetric and geophysical survey and then a detailed survey (complete coverage Seabeam) on two boxes. Finally, rocks... |

| The Gulf of Aden is a young and narrow oceanic basin formed in Oligo-Miocene time between the rifted margins of the Arabian and Somalian plates. Its mean orientation, N75 degrees E, strikes obliquely (50 degrees) to the N25 degrees E opening direction. The western conjugate margins are masked by Oligo-Miocene lavas from the Afar Plume. This paper concerns the eastern margins, where the 19-35 Ma breakup structures are well exposed onshore and within the sediment-starved marine shelf. Those passive margins, about 200 km distant, are non-volcanic. Offshore, during the Encens-Sheba cruise we gathered swath bathymetry, single-channel seismic reflection, gravity and magnetism data, in order to compare the structure of the two conjugate margins and to reconstruct... |
