Writeup from MB 104:

Northwest Africa 10212 (NWA 10212)

(Northwest Africa)

Purchased: 6 Dec 2014

Classification: Ordinary chondrite (LL3-6)

History: One fragment of 46.6 g was purchased in Hamburg on Dec. 6, 2014, from a dealer from Morocco.

Petrography: A random sampling was obtained indicating minor to moderate degree of unequilibration of olivine and pyroxene. A microscopic study shows that the rock is a chondritic breccia consisting of various types of equilibrated lithologies (types LL4-6 fragments) and minor amounts of unequilibrated clasts. The sample also contains impact melt clasts. The sample is a relatively fresh (W1). The olivines show planar fractures clearly indicating shock stage S3.

Geochemistry: Olivine Fa29.0±1.5 (Fa 23-31; n=20), orthopyroxene: Fs23.4±7.8Wo2.4±1.8 (Fs10-51Wo0.4-8.5; n=20).
