The major objective of this cruise was to determine the geology (lithology, tectonic structuring, modalities of magmatism and hydrothermal alteration) of a new type of non-volcanic "smooth seafloor" discovered in 2003 during a previous cruise on the South-western Indian Ridge. This falls under the ANR RIFT2RIDGE project.
