Northwest Africa 10591 (NWA 10591)

Morocco

Purchased: 2015

Classification: Carbonaceous chondrite (CR2)

Petrography: The average chondrule size is ~900 μm; some chondrules have igneous rims. Some chondrules are rimmed by small metal blebs and limonite formed by terrestrial weathering of the metal. Some chondrules contain abundant devitrified glass. There are also metal spherules in the matrix up to 600 μm in size. Some chondrules contain internal metal spherules ranging in size from 50-250 μm. The meteorite contains ~45 vol.% matrix. Sulfide is very rare, <1 vol.%.

Geochemistry: Olivine Fa1.7±1.0, n=23; low-Ca pyroxene Fs2.2±1.1Wo1.1±0.8, n=16.
