Abstract
We performed heating experiments of a eucrite to better understand the origin of textures and mineral chemistry of highly metamorphosed eucrites. Our experiments showed that mesostasis portions, composed of quartz, ilmenite, and Ca-phosphates, are preferentially melted. Since these phases can be carrier phases of trace elements in eucrite, the partial melting during metamorphism could be the cause of disturbance of isotopic ages (e.g., Sm-Nd), redistribution of trace elements.
