Measurement of Cl⁻ : Br⁻ Ratios in the Porewater of Clay-Rich Rocks—A Comparison of the Crush-and-Leach and the Paper-Absorption Methods

Figure 8

Pore throat diameters quantified by MIP. Opalinus clay data (adapted from [35]) from a pair of samples from the Mont Terri Rock Laboratory (borehole BCS-2, gallery 98). Data for the Michigan Basin (adapted from [36]) are from the Queenston, Georgian Bay, and Blue Mountain formation shales. The error bars represent standard deviation.
