Comparison of the K2O and P2O5 contents of the 7 GPa near-solidus melt with that of lunar KREEP rocks (Ryder 1976; Ryder et al. 1977; Irving 1977) and average normal (N-) and enriched (E-) MORB (Klein 2004). The N-MORB data are for the Kolbeinsey, normal East Pacific, and Mid-Cayman ridges. The E-MORB data are for the Mid-Atlantic Ridge
