Ym. Zhu et al., GEOCHEMICAL SIGNIFICANCE OF PYRROLIC NITROGEN-COMPOUNDS IN VARIOUS KINDS OF CRUDE OILS FROM THE TARIM BASIN, Chinese Science Bulletin, 43(16), 1998, pp. 1366-1370
This is a report of the differences in abundances of pyrrolic nitrogen
compounds and distribution of alkylated carbazoles among various oils
from the Tarim Basin. At the same time, their geochemical significanc
e is discussed.
