According to Dr. Randy Korotev results: Dhofar 1627 is a feldspathic impact-melt breccia (S. Seddio and B. Jolliff in MetBull 100) found distant from other Dhofar lunar meteorites. It is among the most mafic of the nominally feldspathic breccias from Oman but is 3-4 times richer in incompatible elements than other meteorites of similar Sc concentration. In both regards the meteorite is similar to regolith from the Apollo 16 site and to lunar meteorite Northwest Africa 4936 (a glassy impact-melt breccia, or possibly regolith breccia; Korotev et al., 2009) and its pair, NWA 5406. Another similarity among the two meteorites and the Apollo 16 regolith is moderately high concentrations of siderophile elements with nonchondritic Ni/Ir. In detail, Sm/Na and Th/U distinguish the two meteorites from each other and from the Apollo 16 regolith. We previously speculated that NWA 4936 might originate from near the Apollo 16 site (Korotev et al., 2009) and the same arguments apply to Dhofar 1627. The meteorite clearly originates in the feldspathic highlands, but some place moderately contaminated, as is the Apollo 16 site, with Sm-rich material from the Procellarum KREEP Terrane.

OK, that's a bit technical, but maybe you can make it friendlier ;-)

The Moon is among the very rarest substances found on Earth. There are only about 280 lunar meteorites classified, and their total weight is less than 160 kg, of which only around 30 kg is actually available on the market outside museums and institutions, and much of that is in the form of small fragments or slices.
