| Research Abstract |
Origin and evolutional process of ultra-high temperature metamorphic terrane were investigated petrologically and mineralogically on the Napier Complex, East Antarctica, as a case study. We examined petrographical features of those rocks and clarified possible existence of metamorphic pressure gradient within the complex based on the difference in reaction products, and mineral stability highly depends on the water activity. Geochronological investigations revealed post-UHT events due to deformation and hydration processes.
