The authors have determined the Pb and Sr isotopic compositions in a number of fresh young oceanic basalts from the East Pacific Rise (between 20 degree N and 21 degree S latitudes), and from the Mid-Atlantic Ridge (between 65 degree N and 10 degree N). The results confirm the Pb-Sr isotopic correlation for mid-ocean ridges basalts obtained by Allegre et al. Cohen et al., Dupre and Allegre and the correlation between isotopic variation and the compatible trace elements ratios variation. A comparison between the Atlantic and Pacific results reveals that there is a wider range of values for the Atlantic than for the Pacific.
