We present the results of a comprehensive major element, trace element and Sr–Nd–Pb–O isotopic study of post-glacial volcanic rocks from the Neovolcanic zones on Iceland. The rocks studied range in composition from picrites and tholeiites, which dominate in the main rift systems, to transitional and...
