3D SR-µXCT analysis for lithology detection: Application to Ryugu sample A0159
Published in Meteoritical & Planetary Science, 2025
This paper presents the development of a new method for detecting mineralogical assemblage heterogeneities in millimeter-sized geological samples using X-ray micro-computed tomography (synchrotron radiation data). The method was applied to the Ryugu sample A0159.
