Fig. 6: Results of the mass-balance and scan-line analyses for Sample B.

a Plot of the relative decrease in Ca concentration over relative total mass loss within micro-dissolution seams. b Histograms of the relative frequencies of the quantities plotted in (a). The diamonds above the histograms indicate the median. c Plot of total cumulative distance along a scan-line occupied by dissolution seams in absolute and relative values (compared to total scan-line length, right ordinate) over the total number of seams intercepted by a scan-line. d Relative frequency distribution of the absolute widths of individual dissolution seams (in μm, grey bars) and the relative cumulative width of dissolution seams along a scan-line (in %, yellow bars). The diamonds indicate the medians. The data used to make this figure are provided in Supplementary Data 4.
