Northwest Africa 12511 (NWA 12511)

Morocco

Purchased: 2018

Classification: Ordinary chondrite (LL6)

History: (Ziyao Wang) Purchased by Ziyao Wang from Sbai Mohamed at the mineral show in Beijing in Nov. 2018

Physical characteristics: (Ziyao Wang) one globulare stone of 91 g with some black fusion crust

Petrography: (R. Bartoschewitz, Bart) very poorly defined chondrules in strong recrystallized matrix.

Geochemistry: (R. Bartoschewitz, Bart, P. Appel and B. Mader, Kiel) Olivine Fa31.0±0.3 (n=7); pyroxene Fs24.9±0.4Wo2.1±0.3 (n=18); Ca-pyroxene En46Fs10Wo44 (n=1); feldspar An10Or5 (n=4); chromite CRAL85, FFM91 (n=3). Taenite Ni=44.0, Co=2.0 (n=2) (all wt-%). Magnetic susceptibility (R. Bartoschewitz, Bart) log χ (× 10-9 m3/kg) = 3.44

Classification: Ordinary chondrite (LL6, S2, W2)

Specimens: 19.0 g on deposit at Kiel, Ziyao Wang holds the main mass, and 12 g with Bart.
