Fig. 5From: Laboratory organic matter maturation at high pressures: heat-up effect on vitrinite reflectanceVariation in VR ehu (vitrinite reflectance attained at the end of heat-up to temperature T ehu) of the run products as a function of T ehu (temperature at the end of heat-up) at various pressures. The error bars in VR ehu are ± one standard deviation s VR ehu. The error bars in temperature are ±1 °C for the run products and ±20 °C for the starting materialBack to article page
