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 <500 μm across, and significant porosity as vesicles 10 to 200 μm, some with euhedral grains protruding into the voids. Rare melt pockets to 100 μm. In the two sections, the chondrules in the black clasts are largely integrated into the matrix. A few PO and BO chondrules were recognized. The silicates contain an abundance of small, 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. Specimens: 1237 g at ASU.
