Figure 2
(A) Paleogeographic reconstruction of the late Cretaceous Last Chance and Vernal delta systems of the Ferron Sandstone Member of the Mancos Shale in present-day Utah (after Cotter, 1976 and used with permission of Brigham Young University). The location of a regional cross section, shown in (B), is highlighted, and the locations of the plan-view facies-association maps in Figure 3A–E are shown. (B) Detailed regional cross section through the lowermost shallow-marine tongue of the Last Chance delta system of the Ferron Sandstone Member (parasequence set 1 of Deveugle et al., 2011) (after Garrison and Van den Bergh, 2004 and used with permission of AAPG). Four delta-lobe deposits (parasequences 1.4, 1.5, 1.6, and 1.7 of Deveugle et al., 2011) are modeled in this study.
