Classification: Chondrite H3 S2/W2
Time/Place: 01.2011 in Erfoud, Morocco
Mass: 500g


History: Purchased by Marcin Cimala in 2011 from a dealer in Erfoud, Morocco.
Petrography: (A. Irving and S. Kuehner, UWS; T. Bunch, NAU) Well-formed, fairly closely-packed chondrules are set in a finer matrix.
Geochemistry: Olivine (Fa0.5-33.2, Cr2O3 in ferroan olivine 0.06-0.15 wt.%, mean 0.08 wt.%, sd 0.02 wt.%, N = 8), orthopyroxene (Fs2.8-39.7Wo0.5-2.0, N = 3), clinopyroxene (Fs10.2-10.3Wo31.3-31.8, N = 2). Magnetic susceptibility log χ (× 10-9 m3/kg)=4.97.
Classification: Ordinary chondrite (H3). H group classification based on magnetic susceptibility.
