Abstract:

Hydrocarbons in Patagonian sediments were analyzed to evaluate their biogenic or petrogenic origins. Structural determination by 1H-NMR spectrometry and principal component analysis (PCA) show that the first two principal components accounted for more than 75.7% of the variance. The results indicate that biogenic hydrocarbons have mainly linear hydrocarbon chains and polar groups (high H2, H4, H5, and HCOOH), while petrogenic hydrocarbons show more branched chains and mainly mono-aromatic components, e.g., crude oil (high H1, H1A, and H3) or mainly poly-aromatic components (high H4, and H2A) in weathering oil. © 2009 Springer-Verlag.
