Figure 8. Pristane (Pr)/n-C17 and phytane (Ph)/n-C18 discriminant plot. Data fields for eastern (E.) Kentucky Ohio Shale and Sunbury Shale solvent extracts and Berea oils from Hackley et al. (2021, this issue). Average Berea- and Ohio Shale–reservoired (n = 23) and lower Paleozoic-reservoired (n = 36) oil from E. Ohio according to data from GeoMark (2015) shown for comparison. Organic source fields and process directions after Shanmugam (1985). Huron and Marcellus data (dots) from this study.
