    NWA 8741
    Mesosiderite
    A4 Meteorite
    Morocco

    This slice was cut from a meteorite, acquired from a nomad in Morocco. The mass turned out to be from 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, including the 409 gram one offered here. This Mesosiderite slice displays a mix of some 28.2 % of metallic components and 71.8 % of silicate by volume. The metal inclusions display forms quite unlike the more common octahedrites with their Widmanst├Ątten patterns which most people are used to viewing. Here the metal occurs as smoothly rounded inclusions of various sizes, embedded in a groundmass of olive-brown Pyroxene and Feldspar with some needles of Silica. Mesosiderites are thought to be the result of collisions between metal rich and silicate rich asteroids, mixing their components and combining them. Since there was but one individual found, this complete 409 gram slice is part of a very small number available.
    Overall Measurements: 8.0 x 7.3 x 0.1' inches (20.3 x 18.4 x 0.3 cm), weighs 409 gm (14.42 oz.)


    Estimate: $6,000 - $8,000.

    It would indeed have been much simpler to work with a local auction house, and we had local options. But we never once regretted going with Heritage.
