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

21 studied the distribution of carbazoles in lacustrine source rocks in the Qaidam Basin, suggested that the relative abundance of 1-MCA (methylcarbazole) showed a decreasing trend at immature stage and an increasing trend in the mature stage, while the relative abundance of the other three isomers (2-, 3- and 4-MCA) showed opposite changes, showing a “two-stage” change.

With the increasing maturity, in the coal sample, the content of carbazole compounds showed a trend of first increasing and then decreasing.
