(a) Mapping of the integrated intensity of the calcite 104 reflection. The area is the same as the central part of the porosity shown in Fig. 4, slice z0. The white dashed line represents the profile along which the calcite 104 reflection has been integrated [see panel (b)]. (c) The XRD patterns reconstructed for the five regions of interest (ROI) identified in panel (b) are plotted. Note that the XRD patterns collected in ROIs 3 and 5 are pure calcite (see Fig. 3). The width of the ROI is 1 pixel (10 µm), with the exception of ROI 1 which is larger. The number after Int. × indicates the multiplication factor used to scale the intensity in the plot. |
