^aHI is the hydrogen index (S₂/TOC × 100). TOC is the total organic carbon content in terms of weight percent and S₂ is the mass of hydrocarbons per mass of sample released during programmed pyrolysis between 300 and 650 °C at a heating rate of 25 °C/min. T_max is a thermal maturity indicator that is approximately 39.5 °C lower than the oven temperature that coincides with the maximum release of hydrocarbons during programmed pyrolysis at a heating rate of 25 °C/min.
