Table 4.8 Bulk compositional changes in the three main kerogen types with increasing maturity (after Behar Vandenbroucke 1987). Maturity levels are shown by positions of samples in Fig. 4.15. Type I kerogen is based on the Eocene, upper Green River Formation shale from the Uinta Basin type II is based on theToarcian shales of the Paris Basin (France) and Liassic a shales from Germany and type III on the deltaic sequences from the Upper Cretaceous of the Douala Basin (Cameroon) and from the Tertiary of the Mahakam Delta (Borneo)...

Figure 17. Carbon isotope fractionations as a function of metamorphic grade. (17A) Compilation of measured values of A(Cc-Gr) shows scatter and disequilibrium at greenschist facies and lower temperature conditions. Many amphibohte facies and most granuhte facies samples show a tight clustering of values consistent with isotope equilibration above 600°C. Values in black are from the Adirondacks (from Kitchen and Valley 1995). (17B) Values of 5 C for a Liassic black shale formation (Hoefs and Frey 1976) showing successive approach to equihbiium at maximum T = 500-600°C (from Sharp et al. 1995).
