Part 1: Within the recent literature, the isotopic heterogeneity of ocean island basalts (OIB) is generally ascribed to mixing between any two or more of four isotopically distinct mantle end-member components - DMM, HIMU, EMI and EMU - the origin and precise location of which are still the subject of much debate. An attempt is made here to constrain the geochemical characteristics of these end-member components using literature-derived endmember OIB data. This has confirmed the presence of consistent trace element differences and also suggested certain major element distinctions, which are interpreted to reflect diverse end-member mantle source compositions rather than differences in the pressure and temperature of melting involved in OIB production. EMI basalts, which extend to the lowest \\(^{143}\\)Nd/\\(^{144}\\)Nd values of all OIB, were found to possess the most distinctive major element characteristics, the latter evident as higher SiO\\(_2\\) and lower FeO*, CaO, TiO\\(_2\\), P\\(_2\\)O\\(_5\\) and ... |
