Figure 12. Alternative models for Wilcox growth wedges. A. Conventional, well log (lithostratigraphic) correlation holds that expansion across major growth faults is limited to Upper Wilcox Group and overlying Queen City Formations. B. Queen City and Upper Wilcox growth is more limited. Model provides for inclusion of an older Wilcox wedge on the downdip side of fault and a coeval updip unconformity. Modified from Snedden et al. (1996b).
