Classification: Chondrite L3 S2 / W0/1
Place/Time: 2018 in Morocco
Mass: 20.86kg

History: Purportedly found in Mali and purchased by Marc Jost from Abdelaziz Mouadine in Rissani, Morocco, in June 2018.
Petrography: (A. Irving and S. Kuehner, UWS) Very fresh specimen composed of very closely packed, well-formed chondrules (apparent diameter 880±400 µm, N = 20) set in a sparse finer grained matrix containing lightly stained metal.
Geochemistry: Olivine (Fa0.6-35.4, Cr2O3 in ferroan examples 0.03-0.13 wt.%, mean 0.06±0.03 wt.%, N = 8), orthopyroxene (Fs3.9-27.8Wo0.3-1.4, N = 3), pigeonite (Fs20.9Wo20.0), diopside (Fs2.1Wo39.3). Magnetic susceptibility log χ (× 10-9 m3/kg) = 4.69

Master pieces polished to the highest mirror level, sharp edges, no scratches. Half of the “wow” effect is the polishing. I guarantee!
All slices both side polished, 6.5mm thin
