Diffractograms from clubs (a) 3, (b) 4 (c) and 5. Red diffractograms stem from areas with high Ap (002) content, black diffractograms from areas with high chitin (110) content, and blue diffractograms show areas with high calcite (104) and (202) content. Blue tick marks indicate standard calcite (Maslen et al., 1995BB20), red tick marks indicate standard Ap (Wilson et al., 1999BB31). The sketches in each panel show the approximate localization of the phases within the clubs. In (a) there is no blue diffractogram or blue dots in the as no calcite was found in club 3.
