Writeup from MB 109:

Northwest Africa 13482 (NWA 13482)

Algeria

Find: 2019 Sep

Classification: CK5-6

History: Found in Algeria close to Ouargla

Physical characteristics: Crusted stone. Cut surface reveals two fine-grained lithologies: a black one and a gray one.

Petrography: (J. Gattacceca, CEREGE) Carbonaceous with two distinct lithologies: one with a petrographic type 5, the other highly recrystallized, type 6 or possibly type 7, with no relict chondrules and triple junctions with euhedral olivine (100 µm), plagioclase (60 µm), and Cr-magnetite (20 µm). Olivine is the dominant mineral. Opaque minerals are Cr-rich magnetite and sulfides.

Geochemistry: Type 5 lithology: olivine Fa34.1±0.5, NiO = 0.63±0.08 wt% (n=3), Ca-pyroxene Fs16.5Wo47.3 (n=1). Type 6 lithology: olivine Fa37.5±0.4, NiO = 0.84±0.26 (n=4), magnetite Cr2O3 = 6.90 wt%.

Classification: Carbonaceous chondrite (CK5-6).

Specimens: Type specimen at CEREGE. Main mass with Jérémy Bassemon.
