Writeup from MB 112:

Northwest Africa 12896 (NWA 12896)

Morocco

Purchased: 2019

Classification: Ordinary chondrite (LL3)

History: (Ziyao Wang) Purchased by Jinji Li from a Moroccan dealer at the mineral show in Chenzhou in May 2019

Physical characteristics: (Ziyao Wang) brown yellow stone of 98 g, without fusion crust

Petrography: (R. Bartoschewitz, Bart) well defined chondrules of 0.3-1.8 mm (av. 0.9 mm, n=22) set in abundant fine-grained brown-stained matrix with a few irregular, mainly oxidized, metal and sulfide aggregates.

Geochemistry: (R. Bartoschewitz, Bart, P. Appel and B. Mader, Kiel) Olivine Fa_19.4(Fa_6.2-32.6; n=28); pyroxene Fs_13.2Wo_1.4±1.4(Fs_0.6-33.9; n=12); chromite CRAL=99, FFM=87 (n=2). Kamacite Ni=5.0-6.6, Co=0.7-1.8 (n=3); taenite Ni=20-40, Co=0.4-1.8 (n=2) (all wt%); troilite. Magnetic susceptibility (R. Bartoschewitz, Bart) log χ (× 10^-9 m³/kg) = 3.69

Classification: Ordinary chondrite (LL3)

Specimens: 15.1 g at Kiel and 5.1 g at Halle on deposit, Jinji Li and Ziyao Wang hold the main mass, and 13 g with Bart.
