Figure F4. Summary stratigraphic section for the Toms River Member of the Shark River Formation (upper middle Eocene) from the Double Trouble borehole. with core recovery (Rec.), lithology (Lith.), gamma ray and resistivity log signatures, age, and environments (Env.). Dino. = Dinocyst zone, Foram. = foraminifer zone, Nanno. = nannofossil zone, Sr = strontium age estimate (Ma), Syst. = systems tract. Lines Res, 16, and 64 are all resistivity logs. NP Zones are from Martini (1971) and Martini and Müller (1986). E and P Zones are from Berggren et al. (1995). E8 is a sequence defined by Browning et al. (1997a, 1997b). See Figure F2B for legend.
