Scientific paper

Trace element concentration patterns of continental and ocean island basalts and of midocean ridge basalts were investigated. The relative sizes of the source regions for these fundamentally different basalt types is estimated from the trace element enrichment/depletion patterns. Their combined volume occupies most of the mantle above the 670 km discontinuity. The separate source regions are the result of early mantle differentiation and crystal fractionation from the resulting melt. The MORB source evolved from an eclogite cumulate which lost its late stage enriched fluids at various times to the shallower mantle and continental crust. The MORB source is primarily garnet and clinopyroxene, while the continental and ocean island basalt source is a garnet peridotite that has experienced secondary enrichment. These relationships are consistent with the evolution of a terrestrial magma ocean.
