The analyses of alkylcarbazoles in the oils from the Pearl River Mouth Basin show that the ratio of 1,3-dimethylcarbazole (DMC) to 1,6-D MC displays a remarkable invariance (about 1) independent of their absolute conc entrations. This may indicate that 1,3- and 1,6-DMC had a common precursor: 1-methylc arbazole. The formation of 1,3- and 1,6-DMC resulted from methylation at ring carbon 3 and 6, which have identical reaction activities, in 1-methylcarbazole in kerogen matrix with identical rate. The 1,4- and 1,5-DMC contents display q uite uniform variance trends as that of 1,3- and 1,6-DMCs in the oils, which indicated during the methylation of 1-methylcarbazole a competitive reaction oc curred between ring carbon 3, 6 and ring carbon 4, 5 in 1-methylcarbazole.
