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...
