Figure F8. Isopach maps of Units (A) S.III, (B) S.II, (C) S.IB, and (D) S.IA showing the eastward migration of depocenters as the Dome underwent continuing uplift. E. Schematic evolution of Units S.II and S.IB based on seismic stratigraphic relationships. Evidence of continuing uplift is also seen in the stratigraphic patterns within these units, which show conformable strata downdip of offlapping strata which overlie a monocline. This reconstruction is based on the portion of 3-D Line 230 shown in Figure F3F, p. 20.
