Influence of thermal maturity on carbazole distributions in coal source rocks during compaction pyrolysis experiments

Scientific Reports
Carbazole compounds are widely used in determining the direction of petroleum migration, but the effect of thermal maturity on carbazoles is still ambiguity. In this paper, using compaction pyrolysis simulation experiments, artificial mature samples with
