Bardaï 001        21°45’21"N , 16°50’57"E

Borkou-Ennedi-Tibesti, Chad

Find: 2005

Classification: Ordinary chondrite (H3-5)

History: Belgian members of an NGO working in Ndrali, Tibesti, found this meteorite in a flat, sand- and gravel-covered area, 30 km north of Ndrali settlement. The nine fragments were dispersed over about 2 km. One of the finders sold the meteorite to Vincent Jacques on his return to Belgium.

Physical characteristics: The largest piece weighs 5.2 kg. All pieces are mostly covered by a dark-brown fusion crust with visible regmaglypts.

Petrography: Light-dark breccia texture, with rounded equilibrated light clasts (cm-sized or smaller) set in a dark, unequilibrated lithology with well delineated chondrules. The host lithology contains melt pockets, melt veins, and metal veins. The dark host lithology dominates.

Geochemistry: Equilibrated clasts: Fa19.6±1.0 (n=5), Fs16.8±1.5Wo1.6±0.2 (n=5). Unequilibrated host lithology Fa18.4±3.0 (n=6), Fs14.8±4Wo1.4±0.2 (n=7).

Classification: Ordinary chondrite H3-5 (or possibly H3-6)

Specimens distributed between CEREGE (10.6 g), RBINS Brussels (45.7 g) and MNHNP (25.5 g).
