The Magma Ocean Concept

1
The Magma Ocean Concept
The lunar magma ocean crystallized sequentially,
producing a mineralogically and compositionally
zoned cumulate pile.
2
Equilibrium Crystallization Sequence
Crystallization sequences for two proposed lunar
bulk compositions, one rich in refractory
elements compared to Earth (TWM) and the other
more like the Earth (LPUM).

Rising Diapirs and Formation of the Mg-Suite
(Elardo et al., 2011)
Rising diapirs of olivine-rich, magnesian
cumulate rocks stall near the crust/mantle
boundary and react with KREEP and crustal
anorthosite.
