Figure F36. Concentration-depth profiles of Sr²⁺, Ca²⁺, and Li⁺ at Site 1171 with approximate location of lithostratigraphic and biostratigraphic boundaries (see "Lithostratigraphy" and "Biostratigraphy"). For comparison, CaCO₃ content (see "Organic Geochemistry") and Sr²⁺/Ca²⁺ and Li⁺/Ca²⁺ ratios are plotted. Standard seawater (SW) concentrations are indicated.
