Figure 5. Plot of hydrogen index (HI, S2×100/total organic carbon [TOC] in milligrams of hydrocarbons per gram TOC) versus the temperature at the S2 peak of programmed pyrolysis (Tmax) (°C) showing evolution of kerogen composition with thermal maturity. Maturation boundaries are based on Peters and Cassa (1994) and Baskin (1997). The kerogen type evolution lines are based on Espitalié et al. (1985) and Hart and Steen (2015).
