    THE NWA 6252 LUNAR METEORITE - A SLICE OF THE MOON
    Achondrite (lunar feldspathic breccia)
    Algeria

    Purchased in Morocco in 2010 from nomadic Berbers, NWA 6252 - the 6,252nd meteorite to be classified after having been recovered in the Sahara Desert - is a lunar breccia, which is to say several discreet materials were fused together following repeated asteroid impacts on the lunar surface. NWA 6252 is also paired (the scientific confirmation of two meteorites found in the same general area at different times which originate from the same cosmic event) with NWA 2995 and its additional pairings. This specimen includes anorthositic, noritic and olivine basaltic lithologies and has lunar highland affinities. Impact melts and breccia-in-breccia structures are also in evidence. As it regards the latter, at least four generations of brecciation were detected in a different specimen. Extremely fresh, NWA 6252 shows little internal indication of terrestrialization (the weathering and erosion due to the elements). Specimens of the Moon can be readily identified by their unique geological, mineralogical, chemical and radiation signatures. The most common minerals found on Earth's surface are not found on the Moon; the minerals comprising the Moon's crust are limited and readily identifiable. In addition, lunar rocks contain gases originating from the solar wind with isotope ratios that are very different than the same gases found on Earth. This select representation of the Moon features an anorthositic clast perfectly positioned in proximity to what would be the nose of an anthropomorphic caricature (see Picasso's "Nude, Green Leaves and Bust"). Accompanied by the NWA 6252 abstract in the Meteoritical Bulletin. There is less than 135 pounds of lunar meteorites documented which makes the Moon, along with Mars, among the rarest objects on Earth. 45 x 32 x 2mm (1.75 x 1.25 x 0.1 inches) and 4.091 grams.

    Provenance: Macovich Collection


    Estimate: $3,000 - $5,000.
