The development and refinement of seismic stratigraphic techniques over the past decade have added the dimension of large scale stratal geometries to stratigraphic correlations, and given renewed impetus to regional correlations based upon unconformity-bounded (allothemic) sequences (Vail, 1976; Vail et al., 1977; 1980; 1982; Vail and Todd, 1981, Todd and Mitchum, 1977). Seismic data compensate for the generally incomplete rock record in outcrop; however, because of seismic resolution limits, outcrop–based studies have provided a direct method to document the age and physical character of seismic sequence boundaries. The integration of outcrop and seismic observations has provided a framework to...
