Fig. 4From: Laboratory organic matter maturation at high pressures: heat-up effect on vitrinite reflectanceDistribution of N measurements of VR performed on textinite/telinite of the run products from the isobaric heat-up experiments to temperatures T ehu (temperature at the end of heat-up) at pressures P. The indicated value VR for each run product is the mean value of vitrinite reflectance ± one standard deviation. VR data are listed in Table 1 Back to article page
