Materials, Vol. 7, Pages 3319-3336: Quantitative Study of Porosity and Pore Features in Moldavites by Means of X-ray Micro-CT (Materials)

X-ray micro-computer aided tomography (?-CT), together with optical microscopy and imaging, have been applied to the study of six moldavite samples. These techniques enabled a complete characterization to be made of the textural features of both Muong Nong-type and common splashform moldavites. A detailed study of the size and distribution of pores or bubbles confirmed the marked variability in pore size among the samples, as well as within each sample, and indicated in the Muong Nong-type moldavites the presence of at least two deformation stages which occurred before and after pore formation.
