Lunar Anorthosite Parent Magma COSMOCHEMISTRY iLLUSTRATED Lunar Anorthosites and the Magma Ocean Concept Anorthosite Lunar anorthosites are thought to have crystallized in a global magma system to form the primary lunar crust. Its crystallization can be tracked by assessing the composition of the magma. How? Measure concentrations of trace elements in individual minerals.
