Two MUSES-C analog samples and a CM2 meteorite (the Murray meteorite) were imaged three-dimensionally without breaking the samples by an X-ray CT system at SPring-8 with the spatial resolution of about 10 micrometers. Based on the empirical relation between the CT-values, f, of materials in CT images and their X-ray linear attenuation coefficient, mu. (f = 0.9 mu), we estimated materials in the samples from their CT-values with the aid of image analysis technique (CBC-MS analysis). 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.
