Figure 8. Core and wire-line logs for a “typical” south dome well, #277. Horizons 100, 200, 300, and 400 have paleosoil-related features below them and are interpreted as sequence boundaries. Thin shales are immediately above sequence boundaries 300 and 400. Stable isotope data are from whole rock samples. GRNST = grainstone; PKST = packstone; WKST = wackestone; MUDST = mudstone.
