 | | In the case of thorium on the Moon, cosmochemists were concerned that the theoretical corrections were giving concentrations a bit too high in areas thought to have quite low thorium, namely in the lunar highlands on the farside. |
 | | In 1998, Warren and his colleague Greg Kallemeyn proposed that as the original globe-encompassing magma ocean was nearing the end of its crystallization all the elements that did not go into the main minerals (thorium, rare earth elements, etc.) concentrated in a layer near the base of the crust. |
