Figure F21. Rock-Eval van Krevelen-type diagram of sediment samples from Hole 1259A. Organic matter appears to be predominantly Type II algal material that has been variably oxidized. Incorporation of organic detrital material possibly gives rise to those samples that fall between Types II and III. TOC = total organic carbon.
