Figure 5. Downcore profiles of Ca2+, Mg2+, the Ca2+/Mg2+ molar ratio, and dissolved Sr2+ in interstitial waters of sites drilled during Leg 175 (except Site 1087; see text). For graphical clarity, profiles of dissolved Ca2+ and Mg2+ are provided for representative sites only. All panels for a given dissolved constituent are plotted to a common scale on the abscissa and to the identical depth scale. For complete profiles to total depth at a given site, please refer to the individual site chapters (this volume). Shaded regions of dissolved Mg2+ profiles indicate regions of current dolomite precipitation (see text). Inset shows an expanded view of dissolved Sr2+ at Site 1077 (Congo Basin). The concentration values of CaCO3 in the sediments (in weight percent) are taken from the "Organic Geochemistry" sections of the individual site chapters (this volume).
