MINERALOGICAL LABORATORY group focus on formation and evolution of the solar system materials from minerals occurring in the Earth and extraterrestrial materials coming from asteroids and comets. We aim to understand the precursor materials of the solar system and their evolution processes.
Our analytical apparatus such as FE-SEM, FE-SEM/FIB, FE-TEM/STEM, and XRD, and several high temperature furnaces make it possible to analyze minerals in nm scale and perform experiments of mineral formation, chemical reaction, and phase transformation under terrestrial and circumstellar environments. We also have been developing a TEM tomography technique in our lab and Micro X-ray CT technique at SPring-8.
“A model for formation and evolution of solid materials in space based on 3D structures of solar primitive materials” was selected as a Grants-in-Aid for Specially Promoted Research by JSPS.
The detailed information of the project is described here.
- Growth, phase transition, and phase separation of minerals
- Research on return samples by space crafts (Hayabusa, Apollo, and Stardust, and future missions such as Hayabusa 2)
- Description of new minerals
- Development of new analytical techniques (Micro X-ray Computer Tomography and TEM tomography)
Our recent publications are listed here.
- Inconsistency between SEM image and Crystal orientation data obtained by SEM-EBSD systems and the solution. here
