Figure 32. Comparison of Rock-Eval hydrogen index (HI) values and TOC concentrations of sediments from Holes 1078A, 1078B, and 1078C. The correspondence between increases in both parameters indicates that preservation of marine organic matter is important in enhancing the organic carbon richness of sediments on the Angola margin.
