Writeup from MB 102:

Boumdeid (2003)        17°42.64’N, 11°22.29’W

Tagant, Mauritania

Fell: 24 Sept 2003

Classification: Ordinary chondrite (L6)

History: (R. Bartoschewitz, Bart) Mr. Isselmou ould Dah lived with his clan north of Gara Dekhene mountain, about 28 km north of Boumdeid. On Sept 24, 2003, between 9 and 10 p.m. he and surrounding nomadic people witnessed a fireball, and short time later a stone fell close to his tent. The stone was still warm when picked up. Later the complete individual of 190 g was broken in many fragments.

Physical characteristics: (R. Bartoschewitz, Bart) One completely crusted individual of 190 g. Magnetic susceptibility log χ = 4.69 (χ × 10-9 m3/kg).

Petrography: (R. Bartoschewitz, Bart) Recrystallized matrix of olivine, Ca-poor pyroxene (0.1-0.5 mm) and secondary feldspar, with poorly developed barred olivine and porphyric pyroxene chondrules (~1 mm), chromite (0.1-0.5 mm), troilite, and metal.

Geochemistry: (R. Bartoschewitz, Bart; P. Appel and B. Mader, Kiel) Olivine Fa24.5-25.1; pyroxene Fs20.2-21.1Wo1.1-1.9; feldspar An10.1-15.7Or 4.9-11.0. Kamacite Ni=4.4-6.6, Co=0.7-1.3 (all in wt.%). Radiochemistry: (D. Degering, Dresden) 22Na=0.041, 26Al=0.07 (in Bq/kg, date 2011 Nov) consistent with a 2003 fall date.

Classification: L chondrite (L6, S2, W0)

Specimens: ~90 g probably lost in Mauritania; type specimen, 20.1 g, MKBraun; 63 g, Bart.
