International audience Hafnium, Nd, and Pb isotope data are reported for mid-ocean ridge basalts (MORB) from the Mid-Atlantic Ridge between 50°N and 78°N. Treating Pb isotopes separately from Sr, Nd, and Hf isotopes drastically reduces the number of end-members required to account for mixing propert...
