Location map of Leg 167 California Margin sites. Age vs. depth plot for Hole 1011B. Figure 4.
Alkalinity shows interplay of organic carbon diagenesis and interactions with the sediments.
Calcium and magnesium show nonconservative profiles in the upper portion from authigenic mineral formation and ion exchange reactions. Silicate values are shown vs. depth and vs. temperature. The much narrower spread of values vs. temperature suggests biogenic opal solubility with temperature as primary control on concentration of dissolved silicate. Thermal gradients at Leg 167 sites.
