Abstract: The present study deals with the geochemistry of Y, Zr, Nb, the rare earths (REE), Hf, Ta and Th in the oceanie environment. These are the so-called "hygromagmaphile" elements, which are characterized by a coherent behaviour in basaltie systems. The results indieate that substantial fractionations occur between these elements during Earth surface processes, from their removal from source rocks to their incorporation into deep-sea sediments.
