Figure F10. Hf vs. Nd diagram showing fields of all available data for the Australian Antarctic Discordance (AAD) region. Dashed line is the Indian Ocean MORB mangle (IMM)/Pacific Ocean MORB mantle (PMM) discriminant boundary of Kempton et al. (2002). Leg 187 and Vema dredge data of Kempton et al. (2002) are shown as points. Fields include all near-axis data from Hanan et al. (2000a, 2000b, submitted N1. TMM = transitional MORB mantle.
