History: Three stones of similar size were purchased by Dr. Albert Jambon in August 2019 from a dealer in Nouakchott, Mauritania. Physical characteristics: About 80% of the surface of each stone is wind ablated with prominent metal veins and wedges separating depressed silicate regions, but remnant regmaglypts can be discerned. Large exposed metal areas exhibit a visible Widmanstätten pattern as thin, shiny taenite bands separating millimetric kamacite with a greenish oxidized surface. The bottom (formerly buried) sides of the stones are covered with remnants of weathered fusion crust. Fine grained olivine and green pyroxene are observed in places where the crust is missing.
