Figure 29. Comparison of Rock-Eval HI values and TOC concentrations of sediments from Hole 1084A. The correspondence between increases in both parameters (in the center of the scatter plot) indicates that preservation of marine organic matter is important to enhancing the organic carbon richness of sediments on the Walvis Ridge. The outliers call for additional explanation.
