Abstract
Ringwood and Essene (1970) proposed that the CaO and Al_2O_3 contents of the deep interior of the moon must be less than 6% each. This constraint has been generally accepted and has led to models of the lunar interior that are dominated by ferromagnesium silicates. This constraint is invalid. High CaO and Al_2O_3 peridotites have broader intermediate-density (3.3–3.4 g/cm^3) fields than the Ringwood-Essene 'lunar pyroxenite', and the high-density phase occurs at higher pressure. Likewise, the gabbro-eclogite transformation pressure increases with Al_2O_3 content. The moon can have a thick plagioclase rich outer shell and a high Ca-Al interior.
