Writeup from MB 111:
Northwest Africa 14668 (NWA 14668) Morocco Purchased: 2008 Classification: Ordinary chondrite (L5) History: Sample was purchased at Tucson Mineral show in 2008 from A. Aaronson, who acquired it from Morocco. Sample is catalogued at the Royal Ontario Museum as M59708. Physical characteristics: Small meteorite with smooth fusion crust surfaces on 3 faces and a large, orange-weathered broken surface, suggesting that it broke off from a larger individual. Desert polish is moderate on fusion crust surfaces and minor on broken surface. Some disseminated metal is visible in broken surface. Physical properties: Magnetic susceptibilty of a 21.51 g specimen is log χ (× 10-9 m3/kg) = 4.27. Petrography: Cut faces show a mottled orange-weathered interior with >mm sized disseminated metal grains and some defined chondrules. In thin section, chondrules are poorly delineated and the matrix is recryatallized. One RP chondrule is 2.3 mm in diameter. Olivine and pyroxene show undulatory to mosaic extinction and some planar fractures. In relfected light, sulfide (4 vol%) in subhedral grains up to 500 µm is more abundant than subrounded metal grains (2 vol%), and both sulfide and metal grains can have associated rims of Fe oxide, which is also observed to line vugs. Classification: Ordinary chondrite: L5 (S3) W2. Low metal content, moderate magnetic susceptibility and the prevalence of sulfide over metal indicates L chondrite.
