According to the model, a magma ocean that differentiated chiefly at low pressure and contained 6-8 wt% A1203 and a subchondritic Ca/Al ratio probably formed the lunar crust.

The subcontinental lithospheric mantle as a mantle reservoir may be modeled by the time-integrated growth of radiogenic ¹⁸⁷Os along retarded (subchondritic) Re/Os trajectories, which results in subchondritic Os isotope compositions.
1999, David Dillon Lambert, Application of radiogenic isotopes to ore deposit research and exploration, page 35If all the Ag were delivered prior to the main phase, the core segregation by about 30 Ma when the Earth was 90% accreted, then a subchondritic ¹⁰⁷Ag/¹⁰⁹Ag would be expected because of strong depletion of siderophile element Pd in the silicate Earth.
