Writeup from MB 111:

Oued Bourdim 003        32°24’01"N, 3°34’56"W

Eastern, Morocco

Purchased: 2022 Jan

Classification: Mesosiderite

History: The meteorite was found about 16 km south of the Talsint mesosiderite find location and subsequently purchased by the main mass holder from a meteorite dealer in Faj Errih, Morocco.

Physical characteristics: Two dark brownish fragments without fusion crust.

Petrography: The meteorite shows a dark brownish interior and is composed of silicate (about 70 vol%) and metallic (about 30 vol%) portions. The silicate fraction is strongly recrystallized and composed of up to 1 mm sized low-Ca pyroxene and calcic plagioclase. Pyroxenes often contain sulfide and metal blebs. The metallic portion consists of kamacite and taenite grains dispersed between the silicates. Accessory minerals include silica, chromite, and merrillite; sulfides are abundant.

Geochemistry: low-Ca pyroxene: Fs26.3±0.5Wo2.6±0.1 (Fs25.5-26.9Wo2.4-2.8, FeO/MnO=24-27, n=8); calcic plagioclase: An91.9±0.7 (An90.5-92.8, n=8)

Classification: Mesosiderite; very similar mineralogy and mineral composition suggest pairing with Talsint.
