3D-image from a granophyre cube analysed using μCT. Note the white crystals at the surface. The dipyramidal shape of the crystals and Raman measurements show that the crystals are anatase when compared with the anatase spectrum from the RRUFF database (RRUFF ID: R07058 [42]). One band from hematite, on which the anatase crystals grew, is also visible in the Raman spectrum (green arrow, RRUFF ID: R050300 [42])
