History: A single stone weighing 332.1 g was found in Morocco and subsequently purchased by Blaine Reed at the 2018 Tucson Gem and Mineral Show. Physical characteristics: The stone is dark-orangish-brown in color, has a flattened ovoid shape, lacks fusion crust and has a weathered exterior with some chondrules protruding from the surface. The cut face showing the interior of the stone is dark greenish-brown and shows readily discernible dark-colored chondrules and irregular to circular dark-gray metallic grains. Petrography: Description and classification (Anthony Love, App): Sample contains distinct chondrules (average diameter of 940 µm (N=24), fragments and refractory inclusions (CAIs up to 3 mm) all set within an opaque dark brown matrix. Matrix contains FeO-rich olivine, andradite, magnetite framboids and one prominent type B dark inclusion. Type I olivine chondrules are dominant (some of which contain isotropic glass). Sample has ~50% matrix. Geochemistry: (A.Love-App) Type I chondrules Fa3.2±2.5 (Fa0.4-8.2), Fe/Mn=37.7±27.3 n=17; Type II chondrules Fa11.14, n=1 low-Ca pyroxene Fs1.1±0.3Wo1.8±1.8 (Fs0.7-1.5Wo0.7-5.0), n=4; high Ca pyroxene Fs1.4Wo26.9, n=1. Classification: Carbonaceous Chondrite (CV3, S2, high weathering) Specimens: Blaine Reed holds the main mass. Two sliced fragments weighing 42.38 g and one polished thin section are on deposit at App.

Physical characteristics: These specimens are noteworthy because of a strong preferred dimensional orientation of elongate, amoeboid to irregularly-shaped CAI. Petrography: (A. Irving, UWS and P. Carpenter, WUSL) Relatively large, well-formed, mostly spherical chondrules (apparent diameter 2170±670 µm, N = 27) are set in a fine grained matrix (~35 vol.%) containing Cr magnetite, pentlandite and rare taenite. Very fine grained CAI examined by electron microprobe analysis contain hedenbergite, aluminous diopside, and calcite.
