In order to recognize the distribution of hydrothermal tracers south of the Azores, a series of cores has been sampled during the GEOFAR cruise. The distribution of the Mn concentrations shows that the hydrothermal influence is maximum within and to the north-west of the Lucky Strike segment. North of the East-Azores Fracture Zone the sediments are enriched in Ba which could be derived from different sources. The chemical composition of the interstitial water shows that...
