Complte slice of TASSEDET004 IMB H5 : 16,8 gr, 36*32*6 mm, both sides polished by myself, nice matrix with many metallic flakes and fusiosn crust. H5-melt breccia. Low weathering, W1, and high shock.. Tassédet 004 ~18°40’30"N, ~7°23’53"E Agadez, Niger Find: 2016 Classification: Ordinary chondrite (H5, melt breccia) History: A large stone of 405 kg was found around 5 km SE of Akokan. It is probably part of a large strewnfield extending for kilometers. Tassédet 004 is widely traded under the name "Tchifaddine." Physical characteristics: Interior shows little to no signs of weathering. Exterior largely dark colored with protruding metal clasts, typically cm-sized. Petrography: Examination of multiple kg of material shows considerable variation in petrography and clast size. This description is based on two representative slices (10 × 8 cm and 18 × 18 cm) and two polished microprobe mounts. The polished slices are dominated by black rounded clasts, surrounded by lighter-colored quenched melt and igneous-textured microporphyritic melt domains. The black clasts show an even distribution of metal and sulfide, typically 2 mm in the melt show eutectic textures. Grains smaller than 2 mm consist of Fe-Ni spheres with coatings of troilite. Chromite is a common accessory as anhedral grains to 200 μm. Feldspar, as anhedral grains, have a wide size distribution from 50 μm. Geochemistry: (L. Garvie, ASU) Black clast: Olivine Fa19.3±1.2, range Fa18.5-22.1, FeO/MnO=39.9±2.9, CaO to 2.2 wt%, Cr2O3=0.1±0.03, range 0.04 to 0.14 wt%, n=9. Low Ca pyroxene, Fs16.7±0.9Wo1.8±0.5, FeO/MnO=23.4±2.5, n=10. Two high-Ca pyroxene grains found, Fs6.8Wo44.4 and Fs6.1Wo45.4. Feldspar Or2.0±0.4Ab76.2±0.9, n=5. Classification: H5-melt breccia. Low weathering, W1, and high shock. Mineralogy and petrography are similar to the Gao-Guenie H5 melt breccia (Schmieder et al., 2016). Tassedet 004 is widely traded under the name Tchifaddine.
