Northwest Africa 10215 (NWA 10215)

Morocco

Purchased: February 2015

Classification: Rumuruti chondrite (R4)

Petrography: The chondrules average 400 μm in diameter, characteristic of R chondrites. There is ~30 vol.% matrix, near the middle of the R-chondrite range. The chondrules are well defined, consistent with type 4.

Geochemistry: The olivine (Fa38.3±1.3, n=18) shows that it is a mostly equilibrated R chondrite. It has little low-Ca pyroxene, Fs13.7±0.9Wo0.30±0.01 (n=2). There is also some Ca-pyx, Fs11.2±0.9 Wo44.0±1.0 (n=4).
