Figure 21. Rock-Eval Van Krevelen–type diagram of sediments from Hole 1079A. Organic matter appears to be a mixture of type II algal material that has been variably oxidized and type III continental or detrital organic matter. HI = milligrams of hydrocarbons per gram of organic carbon; OI = milligrams of CO2 per gram of organic carbon.
