Writeup from MB 101:

Yamato 982881 (Y 982881)

Antarctica

Found: 1998

Classification: Ureilite

Petrography: (A. Yamaguchi, N. Imae, M. Kimura, and H. Kojima, NIPR) The PTS shows a coarse-grained (~1-2 mm) granular texture mainly composed of olivine and pyroxene with thin opaque rims along the boundaries between these minerals. Reduction rims are not apparent. Fe-FeS forms fine chains or islands along fractures near the rims. This rock is moderately weathered judging from brown staining along grain boundaries.

Geochemistry: Compositions of olivine and pyroxene are Fa8-3 and Fs11-17, respectively.

Classification: This meteorite is a ureilite.
