Figure F4. Summary stratigraphic section for the Shark River Formation (middle to uppermost lower Eocene) from the Millville borehole. E4–E10 are sequences defined by Browning et al. (1997a, 1997b). LSF = lowstand shoreface, dLSF = distal lower shoreface, pLSF = proximal lower shoreface. HST = highstand systems tract, MFS = maximum flooding surface, TST = transgressive systems track, FS = flooding surface.
