Writeup |
Writeup from MN J19:
Yamato 981247 (Y 981247) Antarctica Found: 1998 Classification: HED achondrite (Diogenite) Petrography: The section shows a very fine grained (20-100 μm) of laths and wedges of orthopyroxene whose longer axis are broadly aligned. Minute (a few μm) grains of Fe metals and troilite occur. Geochemistry: Pyroxene compositions are En71-76Wo2 (FeO/MnO ~30). Classification: The similar unusual textures and mineral chemistry indicate that Y981247 and Y981582 are paired. These meteorites are diogenites. | ||||||||||||||||
