Writeup from MB 101:

Yamato 983589 (Y 983589)

Antarctica

Found: 1998

Classification: Carbonaceous chondrite (CO3)

Petrography: (A. Yamaguchi, N. Imae, M. Kimura, and H. Kojima, NIPR) The PTS is abundant in small chondrules (100-300 μm), and is slightly weathered (A/B). Silicates commonly show sharp optical extinction, thus the degree of the shock is very low. Small opaque droplets (<30 μm in diameter) are abundant in chondrules. Isolated rounded opaques occur in the similar size of chondrules, and their core metals are rimmed with sulfide.

Classification: This meteorite is CO3.
