Abstract
The most recent review of chemical geodynamics led to the definition of at least four different types of mantle sources (DMM, HIMU, EMI, EMII; (1,2)) from which oceanic basalts may be produced by variable mixing relationships, assuming that oceanic basalt isotope systematics reflect mixing. The existence of two additional components, BSE and PREMA, is also compatible with the observed isotopic heterogeneities in the mantle. The combinations of end-member components for generating individual compositions by mixing are nearly endless. Much more work, especially with a more quantitative approach, will be necessary before we fully understand the geochemical characteristics of the mantle.
