History: Purchased by Michael Farmer in March 2001 from a dealer in Casablanca, Morocco. Petrography: (A. Irving and S. Kuehner, UWS) Sparse chondrules occur in a recrystallized matrix containing stained metal. Geochemistry: Olivine (Fa25.5-25.8, N = 3), orthopyroxene (Fs20.5-20.7Wo1.4-1.6, N = 3), clinopyroxene (Fs7.4-8.3Wo44.9-44.3, N = 2). Classification: Ordinary chondrite (L6). Specimens: 146.7 g including one polished thin section at PSF; 226 g at UCLA; remainder is held by MFarmer.

History: It is quite clear that meteorite collectors in Northwest Africa have discovered a large L chondrite strewn field at an undisclosed location. At least 2 metric tons of material comprising thousands of individuals has been sold under the name NWA 869 in the market places of Morocco and around the world. Individual masses are known to range from 20 kg. It is certain that NWA 869 is paired with other NWA meteorites, although no systematic survey has been done. It is also possible that some stones sold as NWA 869 are not part of the same fall, although dealers are confident that most of the known masses are sufficiently distinctive from other NWA meteorites in terms of surface and internal appearance that the error rate should be fairly low. Scientists are advised to confirm the classification of any specimens they obtain before publishing results under this name. Petrography and Geochemistry: (A. Rubin, UCLA) A fragmental breccia of type 4–6 material; one thin section dominated by an L5 lithology gave olivine (Fa24.2). Classification: Ordinary chondrite (L4–6); W 1, S3. Specimens: A 189.3 g type specimen is on deposit at UCLA.
