Classification:Chondrite L3.6 S2/W1
Place/Time: 02.2013 in Morocco
Mass: 344g


History: Purchased by Marcin Cimala in February 2013 from a dealer in Erfoud, Morocco.
Petrography: (A. Irving and S. Kuehner, UWS) Closely-packed, medium sized, well-formed chondrules (most 0.6-2.8 mm, some up to 4 mm, mean 1.8±1.2mm). Minerals are olivine, orthopyroxene, clinopyroxene, sodic plagioclase, altered kamacite, troilite and chromite.
Geochemistry: Olivine (Fa3.9-32.7, N = 10; Cr2O3 content of ferroan olivine = 0.02±0.02 wt.%, N = 8), orthopyroxene (Fs2.5-8.7Wo0.3-0.5, N = 3), clinopyroxene (Fs3.3-5.2Wo41.9-46.0)
Classification: Ordinary chondrite L3. Estimation of subtype 3.6 based on histograms of Cr2O3 distribution in ferroan olivine given in Fig. 4 of Grossman and Brearley (2005).
