Figure 7
Phase maps for samples WGSI3 and WG102, placed next to µCT images (a) of the same slice for comparison. The different minerals considered for phase mapping are listed on the right. Corresponding space groups and lattice parameters are summarized in Table 2. Two mapping options are shown, using either single-pixel selection (b) or kernel selection (c). With single-pixel selection, the best-matching phase on a pixel is assessed considering only diffraction peaks assigned to this pixel. With kernel selection, the best-matching phase on a pixel is assessed considering all peaks belonging to a 3 × 3 square of pixels around the central pixel, resulting in smoother and more complete phase maps. |
