Abstract
The aromatic hydrocarbon fractions from a series of sediment extracts have been isolated and subjected to proton nuclear magnetic resonance spectroscopy (1H NMR). The NMR results were correlated with maturity data such as Rock—Eval T max values, vitrinite reflectance and specific biomarker ratios. Evidence is presented to indicate that the percentage of aromatic protons in the aromatic fraction (PAP) is proportional to the level of maturity of the sediment. Some kerogens have been subjected to 13C NMR (CP/MAS) and flash pyrolysis—gas chromatography (Py−GC) analysis to provide complementary structural information about the kerogens. The 13C NMR and pyrolysis results are compared with maturity and other organic geochemical data.
