Classification: LL6 melt breccia S2 W0/1
Place/Time: 2018 in Mauritania
Mass: 16 kg

History: Purchased by Aziz Habibi in November 2018 from a Mauritanian dealer.
Petrography: (A. Irving and S. Kuehner, UWS) Relatively fresh, shock-modified breccia consisting of clasts of petrographic type 6 and shock stage S1 (largely recrystallized with rare chondrule remnants and stained metal) in a very fine grained to glassy matrix (black to cinnamon-brown in thin section).
Geochemistry: Olivine (Fa30.8-31.2, N = 3), orthopyroxene (Fs25.1-25.5Wo2.2-1.6, N = 3), clinopyroxene (Fs10.5-10.6Wo42.9-42.7, N = 2). Magnetic susceptibility log χ (× 10-9 m3/kg) = 3.95.

Polished slice with shergottite-like inclusions.
Small slices comes from 1.4kg fragment broken from the original mass to send Type Specimen sample for classification. Remaining main mass 14.5kg will be cut into massive full slices. I’m the owner of the whole mass right now.
