Composition, mineralogy, and petrology of 28 mare basalts from Apollo 15 rake samplesTwenty-eight mare basalts from three Apollo 15 rake sample sections are divided into five rock groups which are considered to represent at least five rock units. Three of these groups (pyroxene-phyric basalt, olivine-phyric basalt, and olivine microgabbro) are from the mare area and are probably near-surface local mare rock units. The remaining groups (feldspathic peridotite and feldspathic microgabbro) are found outside the mare, in Spur Crater at the foot of the Apennines; they may come from deeper levels of the local mare or from a more distant source.
