Abstract

Compound-specific D/H ratios of n-alkanes in soils and immature source rocks can be used to help constrain paleoenvironmental and paleoclimatic conditions. With increasing thermal maturity, however, the isotopic composition of primary biogenic n-alkanes can be altered both by isotopic exchange and the production of thermogenic nalkanes via cracking of sedimentary organic matter.
