Scientific paper

A meteorite (Allan Hills 81005) the size of a golf ball picked off the Antarctic ice early in 1982 is geochemically and petrologically indistinguishable from rocks returned from the lunar highlands. It may be a more pristine sample of the lunar highlands than any rock returned by the Apollo missions because it is very low in KREEP. It is explained how a rock could have been ejected from the moon by an impact without being melted or pulverized by the impact. Even though the geochemical evidence is strong that an Antarctic shergottite (Elephant Moraine 79001) is of Martian origin, there is still no satisfactory explanation of how the rock could have been ejected from that planet.
