Evolution at the release point for a Ca (mg/L) in logarithmic scale, b Ca on exchange sites (mol/g solid), c Mg (mg/L) in logarithmic scale, d Mg on exchange sites (mol/g solid), e Na (mg/L) in logarithmic scale, f Na on exchange sites (mol/g solid), g calcite reaction rate (mol/m2/s) (negative indicates dissolution and positive values indicate precipitation), and h pH. Grey line overlaps with the black line
