Abstract
The equilibrium form of olivine was discussed based on Ab initio calculation. Olivine crystal morphology is important to understand H2 molecules formation in the space and the water origin of the Earth. In this study, the equilibrium form was tried to obtain from morphologies of negative crystals in olivine of LL5-LL6 equilibrated chondrites using micro X-ray tomography. Negative crystals in the Tuxtuac meteorite have similar morphologies, suggesting that they almost correspond to the equilibrium form although the most well-developed facets are (100) surface, which has high surface energy. We will also report results on the Kilabo, Y-75258 and Y793214 meteorites.
