This is a 27.24 gr slice of the meteorite Fezzou 002, an Achondrite meteorite from the Angrite sub-class. Fezzou 002 is a Plutonic Angrite meteorite. Angrites are a very rare type of Achondrites. They are some of the oldest igneous rocks (cooled magmas) in the solar system. As a Plutonic Angrite, it has originated from a more inner part of the Angrites parent body and cooled slower than the Quenched Angrites that come from closer to the surface. This slow cooling allowed for larger crystals to form. I am IMCA member no. 3229 This piece comes with a COA of Mark Lyon (the main mass holder of this classification, see Metbul description below). This piece will be shipped from Switzerland. Basic information Name: Fezzou 002 This is an OFFICIAL meteorite name. Abbreviation: There is no official abbreviation for this meteorite.

Physical characteristics: A single broken stone in two pieces (11340 and 1028 g) with a thin coating of vesicular black fusion crust. Petrography: (A. Irving, UWS, and P. Carpenter, WUSL) The specimen is an aggregate (mean grainsize ~350 µm) of interlocking anhedral grains exhibiting an allotriomorphic-granular texture. Composed predominantly of Al-Ti-augite (pink in thin section), Ca-bearing olivine, kirschsteinite and almost pure anorthite together with accessory hercynitic spinel (pleonaste), troilite and rare Fe metal. Blades or lamellae of kirschsteinite are present within some olivine grains. Some polycrystalline pyroxene-rich clusters and clusters of kirschsteinite+olivine up to ~3 mm in size are present. Vesicles are absent. Geochemistry: Al-Ti-augite (Fs16.3-17.9Wo56.2-57.8, FeO/MnO = 77-101, Al2O3 10.1-11.4 wt.%, TiO2 1.5-2.8 wt.%, N = 5), olivine (Fa59.4-60.5Ln2.4-3.2, FeO/MnO = 61-68, N = 4), kirschsteinite (Fa37.7-39.3Ln45.0-48.1, FeO/MnO = 59-65, N = 4), anorthite (An99.9-100.0Or0.0, N = 4), pleonaste [Fe0.78Mg0.30Al1.88 Ti0.02Cr0.04O4]. Oxygen isotopes (K. Ziegler, UNM): analyses of acid-washed subsamples by laser fluorination gave, respectively δ17O 2.217, 2.194, 2.137; δ18O 4.444, 4.350, 4.239; Δ17O -0.130, -0.103, -0.101 per mil (all data linearized, TFL slope = 0.528). Classification: Angrite (allotriomorphic-granular). Specimens: 34.5 g including one polished thin section at UWB; 40 g at Ministry of Energy Transition and Sustainable Development, Rabat, Morocco; remainder with Mr M. Lyon.
