Figure 11. Plot of gammacerane index (ratio of gammacerane to 17α, 21β-hopane [Ga/Hop]) versus pristane/phytane (Pr/Ph) for Berea oils and solvent extracts. Data for average (n = 21) eastern (E.) Ohio Devonian oil and lower Paleozoic oil (n = 15) from GeoMark (2015); Huron and Marcellus data (dots) from this study.
