Northwest Africa 10052 (NWA 10052)

Morocco

Purchased: 2014

Classification: Carbonaceous chondrite (CR2)

Petrography: Chondrules average ~800 μm in diameter, consistent with CR. There are no large amoeboid olivine inclusions present. There are many large metal grains, consistent with CR. The matrix modal abundance is ~35 vol.%. Low-Ca pyroxene grains typically exhibit polysynthetic twinning. The mean Cr2O3 content of ferroan olivine grains (n=16) is 0.54±0.16 wt.%. Kamacite contains 92.8% Fe, 5.7% Ni, 0.29% Co, 0.13% P, 0.19% Cr.
