Lunar Meteorite: Yamato 793169

Antarctica, Yamato Mountains

 

Yamato 793169. The longest dimension is 1.8 cm. Photo from Yanai and Kojima (1991)



As one of the Yamato 79 meteorites, it's one of the first three known lunar meteorites to be found.

It is an unbrecciated basalt.

It's unlike any basalt from the Apollo and Luna missions.

It is compositionally and mineralogically similar to Asuka 881757 and MIL 05035. All three were likely launched from the same crater on the Moon.
