Research Abstract

This study apply an empirical algorithm to lunar reflectance spectra from the Kaguya and report that magnesium contents relative to iron of primitive crustal highland rocks on the farside are higher than on the nearside. Our findings indicate that the farside crust consists of rocks that crystallized from less-evolved magma than the nearside crust. This indicates that the lunar dichotomy is directly linked to crystallization of the magma ocean and suggests that the composition of the magma ocean was more primitive at the time of crustal growth than previously estimated.
