SIGNIFICANCE OF ISOTOPICALLY LABILE ORGANIC HYDROGEN IN THERMAL MATURATION OF ORGANIC MATTER
- Indiana University, Dept. of Geological Sciences
Isotopically labile organic hydrogen in organic matter occupies chemical positions that participate in isotopic exchange and in chemical reactions during thermal maturation. We monitor and interpret changes in the H-isotopic exchangeability and D/H ratio in maturing kerogens in order to evaluate the diagenetic and/or paleoenvironmental significance of OD values in different types of kerogen, and in the maturation products oil and fractions of oil. We investigate the utility of FTIR, NMR, and Raman Spectroscopy as proxies for thermal maturation, and the paleoenvironmental significance of an apparent correlation between hydrogen exchangeability and the O15N values in kerogens in stratigraphic sequences.
