There is now abundant geophysical and geochemical evidence suggesting that the moon has a thick plagioclase rich outer shell. This is most easily explained by early and extensive melting of a CaO and Al_2O_3 rich moon followed by fractional crystallization involving plagioclase flotation. Melilite is probably an important constituent of the interior. This model explains the seismic velocities, the mean density, and the moment of inertia of the moon. The moon is 73–88% high-temperature condensate.

This note is a combination and condensation of replies written in response to extensive comments by A. E. Ringwood on 'Removal of a constraint on the composition of the lunar interior.' I would like to thank Ringwood for this opportunity to elaborate further on the present constraints regarding the interior of the moon. Although he withdrew his objections, he does not necessarily subscribe to all the views in this paper. This work was supported by NASA grant NGL 05-002-069.
