History: 4 pieces that fit together were found within the Nagjir dense collection area near Bir Anzerane, Western Sahara. Carlos Muñecas (Expometeoritos) purchased the samples in July 2021 from a dealer in Morocco. Physical characteristics: Samples have dark gray-dark brown exteriors and have roughly tabular shapes. The cut face shows the interior has a chondritic texture composed of abundant dark and light-colored chondrules and CAIs set within a dark-colored matrix. Petrography: Description and classification (A. Love, App) Sample contains chondrules w/ avg. dia of 667 µm (n=39) and CAIs set in 22 vol% opaque matrix. Additional minerals are: chromite, very rare troilite, magnetite and rare phosphates. Geochemistry: (A. Love, App) Olivine Fa11.0±11.9 (Fa0.3-34.3, Fe/Mn=58.6±30.0, n=24); low-Ca pyroxene Fs1.5±1.8Wo1.0±0.2 (Fs0.5-5.6Wo0.6-1., n=7). Classification: Carbonaceous chondrite (CV3). Based on textures, mineral compositions, and magnetic susceptibility, sample is a CV3. Specimens: Carlos Muñecas (Expometeoritos) holds the 1676 g main mass. A polished thin section and a 26.69 g slice and endcut are on deposit at App.

History: Purchased In 2006 by A. Aaronson. Physical characteristics: More than 100 kg of dark stones with smooth, desert-polished surfaces. The largest piece is 22.75 kg Petrography: (T. Bunch and J. Wittke, NAU) Well-defined chondrules, chondrule fragments, and refractory inclusions set in a slightly weathered matrix. CAIs are represented by Type A (a few are very large, up to 32 mm in diameter) and Type C are common, as are AOAs. Type B CAIs are low in abundance however, melilite mantled (Type B1) and fosterite bearing type B CAIs are present. Modal analyses (vol. %): chondrules = 48; CAIs and AOAs = 14; matrix = 38. Geochemistry: (M. S. Sapah, ANU, and A. N. Krot, UHaw) The meteorite matrix consists of small crystals of ferroan olivine, sulfides, magnetite, Ni-rich metal, tiny nepheline crystals, and small irregularly shaped regions of Ca,Fe-rich silicates (pyroxenes ± andradite). 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). The sample is CV oxidized. The degree of shock is S2 and the weathering degree is W1. Specimens: >83 kg Aaronson, 35 kg Eric Olson, 2.9 kg ANU, 284.6 g ASU, and 26 g NAU.

History: Found in Niger and purchased in Morocco by Adam Aaronson in August 2018. Petrography: (A. Irving and S. Kuehner, UWS) Well-formed granular and BO chondrules (some composite; apparent diameter 1250 ± 690 µm) and fine grained CAI (some up to 4.5 mm across) are set in a fine grained matrix (~30 vol.%, orange-brown in thin section). Geochemistry: Olivine (Fa0.2-45.3, N = 3), orthopyroxene (Fs0.7-0.9Wo1.1, N = 2), clinopyroxene (Fs2.5Wo36.0; Fs21.4Wo44.1; N = 2). Classification: Carbonaceous chondrite (CV3). Specimens: 42 g including one polished thin section at UWB; remainder with Aaronson.

History: Purchased by Eric Twelker in March 2020 from a Moroccan dealer. Petrography: (A. Irving, UWS and P. Carpenter, WUSL) Well-formed magnetite-bearing chondrules (apparent diameter 800±360 µm, N = 24) plus very fine grained, amoeboid CAI are set in a fine grained matrix (~40 vol.%, sepia-brown to opaque in thin section) containing accessory Cr-bearing magnetite and calcic plagioclase. No sulfides were found. One CAI is composed of gehlenite, perovskite, spinel and pleonaste, and contains a tiny Ir metal nugget. Geochemistry: Olivine (Fa11.8±10.3, range Fa0.3-27.5, N = 5), low-Ca pyroxene (Fs3.0±1.2Wo2.1±2.1, range Fs1.6-3.7Wo0.9-4.5, N = 3), subcalcic augite (Fs0.6Wo32.8), augite (Fs1.4Wo38.2; Fs49.5Wo49.4; N = 2), plagioclase (An80.2Or0.0; An90.1Or0.1; N = 2), magnetite (Cr2O3 = 0.1-1.1 wt.%, N = 3). Classification: Carbonaceous chondrite (CV3, oxidized). Specimens: 21.5 g including one polished thin section at UWB; remainder with Mr. E. Twelker.

History: Purchased by Craig Zlimen in December 2021 from an Algerian dealer. Petrography: (A. Irving, UWS and J. Boesenberg, BrownU) Well-formed, unequilibrated chondrules (some with concentric rims, apparent diameter 1050±400 µm, N = 26) containing both fresh and devitrified glass together with relatively abundant CAI are set in a fine grained matrix (~40 vol.%, sepia brown to opaque in thin section) containing Cr-bearing magnetite, pentlandite, plagioclase and kamacite. Minerals in CAI include anorthite, spinel and gehlenite. Geochemistry: Olivine (Fa23.0±36.0, range Fa1.3-93.9, N = 6), low-Ca pyroxene (Fs1.4±0.6Wo0.8±0.3, range Fs0.7-2.1Wo0.3-1.1, N = 5), subcalcic diopside (Fs1.1Wo31.4), diopside (Fs0.7±0.0Wo45.7±0.6, range Fs0.7±0.0Wo45.3-46.1, N = 2), magnetite (Cr2O3 0.1-1.0 wt.%, N = 6). Classification: Carbonaceous chondrite (CVox3). Specimens: 21.4 g including one polished thin section at UWB; remainder with Mr. C. Zlimen.
