Writeup from MB 109:

Northwest Africa 12302 (NWA 12302)

Morocco

Purchased: 2017

Classification: Carbonaceous chondrite (CV3)

History: (Ziyao Wang) Purchased by Ziyao Wang from Adnane Sami during the China (Hunan) Mineral & Gem Show in Chenzhou City in May 2017.

Physical characteristics: (Ziyao Wang) Dark gray-yellow flat stone of 50 g without fusion crust

Petrography: (R. Bartoschewitz, Bart) well defined chondrules (0.3-1.8 mm, av. 1 mm) of various types (PO, POP, RP, BO, GO), chondrule fragments, and AOAs are set in dark brown opaque matrix (~15%).

Geochemistry: (R. Bartoschewitz, Bart, P. Appel and B. Mader, Kiel) Olivine Fa18.4 (Fa0.2-36.5; Fe/Mn=54; Fe/Mg=0.25; n=15); pyroxene Fs9.4±6.7Wo0.6±0.5 (Fe/Mn=20; Fe/Mg=0.1; n=11); Ca pyroxene En32Fs5Wo63 (n=1); An74Or1 (n=1). Kamacite Ni=6.8, Co=1.7 (n=1); taenite Ni=36.9, Co=0,5 (n=2) (all wt%). Magnetic susceptibility (R. Bartoschewitz, Bart) log χ (× 10-9 m3/kg) = 3.43

Classification: carbonaceous chondrite (CV3, S2)

Specimens: 10.2 g on deposit at Kiel, Ziyao Wang holds the main mass, and 5.5 g with Bart.
