Figure 31. Rock-Eval Van Krevelen-type diagram of sediments from Holes 1078A, 1078B, and 1078C. Organic matter appears to be predominantly type II algal material that has been variably oxidized. HI = milligrams of hydrocarbons per gram of organic carbon; OI = milligrams of CO2 per gram of organic carbon.
