Writeup from MB 110:

Touat 007        27°31.560’N, 0°22.064’W

Adrar, Algeria

Find: 22 Feb 2020

Classification: Iron meteorite (IIIAB)

History: A single, 1594 g mass was found near Adrar by Lahsan in February 2020.

Physical characteristics: The irregularly shaped meteorite has a mottled brown surface with deep reglaglypts. One side is flatter where it may have been exposed to wind abrasion.

Petrography: (C. Herd and P. Hill, UAb) Petrographic investigation of a ~3 × 5 cm polished and etched surface reveals a well-developed Widmanstaetten pattern with a bandwidth of 1.1 ± 0.2 mm (n=23). No inclusions were observed. Some terrestrial alteration extends along grain boundaries into the interior.

Geochemistry: ICP-MS data, using sample of North Chile (Filomena) as standard (C. Herd, P. Hill, and S. DuFrane UAb): Ni = 8.0, Co = 0.51 (both wt%); Ir = 0.52, Ga = 19, Ge = 46, As = 7.2, Sb = 0.12, Ru = 5.5, Re = 0.03, Os = 0.25, W = 0.5, Pt = 8.2, Cu = 136, Au = 0.73 (all μg/g). Au value is a minimum due to uncertainties associated with the solution ICP-MS method.

Classification: (C. Herd, UAb): IIIAB iron, medium octahedrite.

Specimens: Type specimen consisting of a 87.2 g end piece at UAb. Main mass with Dave Lehman (NWA Direct).
