Matrix olivine has Fa48-54 and ferrosillite and wollastonite contents of matrix pyroxenes are 11-19% and 46-49% respectively. Fayalite content of chondrule olivine is Fa2-39, and ferrosillite and wollasonite contents of chondrule pyroxenes are 1-2%. Classification: (M. S. Sapah and A. N. Krot) Carbonaceous chondrite (CV3).

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.

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. Geochemistry: Olivine (Fa7.1±4.9, range Fa0.4-13.4, N = 5), low-Ca pyroxene (Fs0.7±0.1Wo3.3±2.2, range Fs0.6-0.8Wo0.9-5.2, N = 3), diopside (Fs1.2±0.2Wo41.2±1.1, range Fs1.0-1.3Wo42.0-40.4, N = 2), magnetite (Cr2O3 0.3-1.6 wt.%, N = 7).
