Continental intraplate basalts with a HIMU-like mantle signature in the SW Pacific (e.g. New Zealand, Australia and Antarctica) have been erupted over an area of ∼25 million km2 sporadically over the last c . 100 Myr. This long-lived HIMU signature has recently been ascribed to both melting in the s...
