Scientific paper

It is shown that the orbital geochemical data of the moon can be used in geochemical variation diagrams like those employed in lunar sample studies to define petrologic units within the highlands, to determine their geologic interrelations, and to address problems of crustal genesis on a near-global scale. Three variation diarams based on Apollo geochemical data were examined: Mg(asterisk) versus (Th/Ti)c, Al versus Mg(asterisk)/(Th/Ti)c, and Fe versus (Th/Ti)c. The diagrams show some units of virtually pure anorthosite and norite; most units show the effects of mixing of pristine rock types in the regolith. One unit, which dominates the eastern limb and farside highlands, has a composition so mafic that, with the chosen end members, it requires a 30 percent mare basalt component. This is interpreted to mean that the highlands experienced a significantly greater amount of mare volcanism before the end of heavy bombardment than has previously been suggested.
