    NWA 8741
    Mesosiderite
    A4 Meterorite
    Morocco

    In April of 2014, a 22.3 kilogram "probable" meteorite was purchased by a dealer, from a nomad in Erfoud, Morocco. It turned out to be one of four Mesosiderites of the A-4 sub-group known. After analysis, it was named NWA 8741 and subsequently, a few slices were cut and polished from the mass. Intermediate in composition between Iron meteorites and stony ones, this Mesosiderite displays a mix of some 28.2 % of metallic components and 71.8 % of silicate ones by volume. The metal displays forms quite unlike the more common octahedrite structures most people are used to seeing. Here the metal occurs as smoothly rounded shapes of various sizes, embedded in a groundmass of olive-brown Pyroxene and Feldspar, with some needles of Silica thrown in for variety. Mesosiderites are thought to be the result of collisions between metal rich and silicate rich asteroids. Since there was but one individual found, this complete 532 gram slice is part of a very limited "edition" and represents a fairly rare opportunity to acquire a complete slice of this unusual cosmic visitor.
    Overall Measurements: 7.8 x 7.8 x 0.1 inches (19.7 x 19.8 x 0.3 cm), weighs 532 gm (18.76 oz.)


    Estimate: $7,000 - $10,000.
