Kereb es Sefiat 002 (KeS 002) 27.683°N, 7.419°W

Tindouf, Algeria

Find: 2021 Mar

Classification: Ordinary chondrite (H3)

History: Found in Algeria in March 2021 at 27.683°N, 7.419°W and purchased by Matthew Stream in August 2021 from an Algerian dealer.

Petrography: (A. Irving, UWS and J. Boesenberg, BrownU) Relatively small well-formed, unequilibrated chondrules (apparent diameter 460±300 µm, N = 25) containing devitrified glass are set in a fine grained matrix containing altered kamacite, chromite and troilite.

Geochemistry: Olivine (Fa_20.0±9.5, range Fa_1.9-31.6, N = 12; Cr₂O₃ in ferroan olivine 0.02-0.56 wt.%, mean 0.12±0.17 wt.%, N = 10), low-Ca pyroxene (Fs_16.3±10.7Wo_1.5±0.9, range Fs_5.5-27.5Wo_0.4-2.6, N = 4), pigeonite (Fs_13.1Wo_6.1; Fs_21.7Wo_16.2; N = 2), augite (Fs_12.1Wo_36.2). Magnetic susceptibility log χ (× 10^-9 m³/kg) = 4.96.

Classification: Ordinary chondrite (H3).

Specimens: 14.9 g including one polished thin section at UWB; remainder with Mr. M. Stream.
