New major and trace element and Sr–Nd–Pb isotope data have been determined for 21 basaltic samples from São Jorge Island, Azores archipelago. Samples can be separated into two groups best identified in a plot of 208Pb/204Pb versus 206Pb/204Pb where they form two sub-parallel mixing arrays. Lavas fro...
