    Description

    My name is Ruben Garcia aka MrMeteorite and I’m a meteorite dealer/collector.   I have dealt in meteorites since 1998, and it's been a wonderful ride!
    I’ve been featured in many books and magazines about meteorites, like Sky and Telescope, Discover, Iguana, Meteorite Times, and even the latest book by O. Richard and Dorothy Norton, called “What’s so Mysterious about Meteorites?”
    I’ve also appeared in such TV shows as, Meteorite Men, Nova Science NOW, Cash and Treasures, and the United Stats of America with Hosts “The Sklar Brothers”. Of course, I’ve also been the subject of newspapers all across the country and various NPR and BBC radio shows.
    I typically sell to high profile museums and universities all over the world. Everything I sell here is guaranteed just as if I were selling to a museum.

    Northwest Africa 13917
    (NWA 13917)
    (Northwest Africa)
    Purchased: 2020
    Classification: Primitive achondrite (Winonaite)
    History
    : Purchased from Morocco in September 2020 and January 2021.
    Physical characteristics
    : Several identical appearing stones found together -- the largest of which are individuals weighing 1.6 kg, 1.4 kg, and 1.2 kg. Saw-cut surface shows abundant fine-grained metal and sulfide set in a mosaic of brown and gray silicate minerals. A prominent metal vein 2 mm thick and several cm in length crosscuts the deposit sample slice.
    Petrography
    : (C. Agee,
    UNM
    ) Microprobe examination of a polished mount shows a texturally equilibrated mosaic of enstatite and diopside with grain size in the range 100-300 μm, many triple junctions are present. Forsterite is ubiquitous but is significantly less abundant than the pyroxenes. Kamacite, taenite, and troilite make up approximately 10% of this meteorite, most grains are 100-300 μm in diameter. A phosphate phase was detected. No feldspar was observed in the microprobe mount.
