[[:file:oiloil-and-oilsource-rock-correlations_fig8-14.png|Figure 10]] shows gas chromatograms of saturated hydrocarbons from an immature extract of coaly organic matter (top) and an oil with a fairly high wax content believed to have been sourced from a similar facies (bottom). Both show many of the same characteristics—high wax content, odd-carbon preference in the wax range, high [[pristane–phytane ratio]]—but maturity effects have changed many of the details.
