Summary:This comment on the paper by O'Hara points out that recent work indicates that the bulk lunar crust has 30% Al2O3 not 24.6% as used by O'Hara, and this requires dry magma flotation of plagioclase concentrating ∼50% of the Al and Eu in the crust leaving a Eu anomaly in the mantle. Wet partial melting is rejected because of the anhydrous nature of all lunar materials. [B.E.L.]
