Crystallographic Analyses for Textures and Growth Processes of Minerals

Abstract

Various mineral species are produced by geological process. Dynamical processes in the Earth expand varieties of mineral species, and their textures and crystal structures. Mineral textures include historical information about the growth, transition and deformation of the minerals in the Erath. Hence, analyses of mineral textures are conducted macro- to nano-scale using optical and electron microscopies. I present our study about lutecite, which is a kind of aggregate of fine quartz and mogánite crystals, and discuss metastable precipitation processes of minerals in geological conditions.
