Figure F3. Kirkwood-Cohansey (middle to upper Miocene) and Kw3 (middle Miocene) sequences from the Kirkwood Formation at the Ocean View borehole. Kirkwood-Cohansey and Kw3 are sequences defined by Miller et al. (1997) and Sugarman et al. (1993). uHST = upper highstand systems tract, lHST = lower highstand systems tract, MFS = maximum flooding surface, TST = transgressive systems tract. The key to lithologic symbols is given in Figure F2.
