Identification of clastic mineral composition by comparing attenuation- and XRD-contrast sinograms. (a) An attenuation-contrast cross section of the sample. Three inclusions are marked with red rectangles and have been magnified. A sinogram (Radon transform) of the entire cross section in (a). (c) A sinogram made by including only the bright regions indicated by the red rectangles in (a). (d) XRD-CT sinograms based on clinochlore 001, illite 001, clinochlore 002/kaolinite 002, quartz {011} (overlapping with clinochlore and illite), and pyrite {200}. All sinograms are displayed with different intensity scales. The white dashed line is a guide to the eye.
