Qara        2°4.031’N, 39°1.016’E

North-Eastern, Kenya

Purchased: 2020 May

Classification: Iron meteorite (IIAB)

History: Single piece of iron was bought from Mr. Abdiqani Hussein, in Nairobi, Kenya in May 2020. Mr. Abdiqani Hussein stated that meteorite was found in the desert at coordinates: 2°04.031’N; 39°01.016’E

Physical characteristics: The meteorite has cone-like shape (35 × 28 cm); a surface has some regmaglypts and is covered by a shell of iron oxides. Total weight is 19.95 kg.

Petrography: (G. Skridlaite, Vilnius University), L. Siliauskas (Nature Research Centre, Vilnius). The meteorite comprises mostly low-Ni metal (kamacite) with minor taenite lamellas of ~5-20 µm in width. Widmanstätten structure is absent. Inclusions of troilite and graphite up to 5 cm in size are presented. Minor minerals are schreibersite which forms euhedral crystals, and olivine inclusions in graphite. Neumann lines were observed. The products of terrestrial weathering are Fe, Ni hydroxides.

Geochemistry: Mineral composition and geochemistry: (B. Knašienė, E. Naujalis, Vilnius University), metal composition, all in ppm: Ni 62586; Co 4432; Cu 153; Zn 40.2; Ga 113; As 44.9; Ir 10.3; Pt 20; Au <2; W 2.5; Re 1.2.

Classification: Based on the bulk Ni concentration and abundances of trace elements the meteorite is related to chemical group IIAB. Texture of the meteorite corresponds to hexahedrite. The meteorite is moderately weathered.

Specimens: Total 214 g are on deposit at GMVU and 345 g are on deposit at Vernad. Mr. Michail Ivanov holds the main mass of the meteorite.
