Lunar Meteorite: Yamato 82192, 82193, & 86032 (paired stones)

Antarctica, Yamato Mountains


Yamato 82192 and 82193 (no photos) are small stones found during the 1982/1983 JARE-NIPR field season. Yamato 86032, pictured above, is a large stone found 4 years later about 2 km away. They are different stones from a single fall. Photo from Figure 1 of Takeda et al. (1989).
