Data are presented in connection with shipboard study ; a tentative interpretation is given taking into account our present knowledge of the behavior of trace elements during magmatic processes and comparing the results of FAMOUS, Leg 37 and Leg 45. We ask the reader to look at our Leg 45 report (Bougault. et al., 1978) to gain information about analytical procedures and geochemical methods of investigation.
