Description:
Several investigators have studied soils from the lunar highlands with the objective of recognizing the parent rocks that have contributed significant amounts of material to these soils. Comparing only major element data, and thus avoiding the problems induced by individual classifications, these data appear to converge on a relatively limited number of rock types. The highland soils are derived from a suite of highly feldspathic rocks comprising anorthositic gabbros (or norites), high alumina basalts, troctolites, and less abundant gabbroic (or noritic) anorthosites, anorthosites, and KREEP basalts.
