Writeup from MN J24:

Yamato 002712


The PTS displays a medium-grained (~0.1-0.3 mm) ophitic texture composed of pyroxene and maskelynite. Plagioclase is not found. Minor sulfide and oxide minerals (~50-200 μm) are scattered sparsely. There is a thin shock melt vein (the lower-left of the figure). Textural and compositional similarities indicate that Y 002712 may be paired with Y 002192. This meteorite is a Martian meteorite (shergottite).
