A micro-tomographic System developed at BL47XU in SPring-8 (SP- $\mu$CT 47XU) was used to obtain three-dimensional structures of synthetic and natural substances for a test study. Al 2O 3-YAG cutectic composites, synthetic quartzites (SiO 2) and Antarctic micro-meteorites (AMMs) were successfully imaged with the spatial resolution of 1  $\mu$m three-dimensionally. Three-dimensional elemental distribution was also obtained using X-ray adsorption edge of Fe in the measurement of an AMM.
