Information from the Apollo missions has led some investigators to favor a warm ancient Moon (Smith et al., 1970; Wood,1972). This idea has been most recently amplified by Wood (1975) and Walker et al.(1975) who suggest that the petrology of the ancient anorthositic lunar crust can be explained as having resulted from crystal fractionation and gravitational separation in a well-stirred global subcrustal magma chamber referred to by Wood (1975) as a magma ocean.
