Cohen and O'Nions1 noted that basalts from the Mid-Atlantic Ridge (MAR) display greater diversity of Pb, Nd and Sr isotopes than do basalts from the East Pacific Rise (EPR). They attributed this difference not to greater isotopic heterogeneity beneath the MAR, but rather to more effective mixing (to eradicate heterogeneity) beneath the EPR. Allègre et al.2 reached the same conclusion on the basis of isotope data including noble gas isotopic data. To test this idea further, I compare here the… CONTINUE READING
