[[:file:oiloil-and-oilsource-rock-correlations_fig8-7.png|Figure 3]] shows a gas chromatogram of a low-wax oil derived from typical marine algae. Pristane-phytane ratios for such oils tend to be slightly above 1.0. This Alaskan oil was derived from a source rock containing predominantly marine algal organic matter.
