35.66 grams, and about 60 x 55 x 2 mm.   Cba

TKW 823 grams. Fall not observed. Reportedly found approximately 2 km west of route N2, 5 km east of the boundary of Banc d’Arguin National Park, and 40 km east of the Bay of Arguin in Mauritania. The meteorite was found by a shepherd from Mali who was grazing sheep in the area. The shepherd passed the meteorite on to a worker from a local gold field who in turn sold it to a meteorite dealer.

I was struck by the similarity of Arguin 001 and Gujba and wondered if they might be paired or at least launch paired, but the Metbull sets that straight:

  Visually, polished slices of this meteorite resemble Gujba, however they are not paired as the metal nodules in this meteorite are smaller than those of Gujba and Gujba has less total metal (41 vol. %), Rubin et al. (2003). The exterior color and patina of this meteorite are distinctly different from specimens of Gujba.

  In any case, they are both among the prettiest and most unusual of the chondrites!
