Figure F37. Concentration-depth profiles of Mg²⁺ and K⁺ at Site 1171. For comparison, Mg²⁺/Cl^- and K⁺/Cl^- ratios are plotted. The insert shows the high correlation between Mg²⁺ and K⁺. Approximate locations of lithostratigraphic and biostratigraphic boundaries (see "Lithostratigraphy" and "Biostratigraphy") and standard seawater (SW) concentrations are indicated. The dashed line marks depth of pronounced pore-water chemistry change.
