As the analog samples are fine powders, three-dimensional textures were not examined. High-resolution system (about 1 micrometer spatial resolution) at SPring-8 is useful for such samples. We can successfully recognize chondrules and mineral grains three-dimensionally in the Murray meteorite. The present method is useful to describe three-dimensional structures of unknown samples without breaking samples by using CT-values. We believe that curation of MUSES-C samples will be made effectively. | |||||
