We present data for glassy basalts from ~37 localities along the spreading axis of the Southeast Indian Ridge (SEIR) between 126°-140°E, eastward of the Australian-Antarctic Discordance (AAD). Each of the five ridge segments (A1 to A5, west to east) show well-defined major element trends. An isotopi...
