The fourth zone represents a fluvial origin below to shallow marine above. The third zone is interpreted to be of fluvial-overbank origin with possibly a bay-lagoonal association.ABSTRACT. The Upper Cretaceous Sussex "B" sandstone was deposited as a probable transgressive-marine sand-ridge complex in a mid-shelf position. The "B" sandstone is bounded by upper and basal disconformities and encased in mudstones and low-porosity and low-permeability sandstones of the Cody Shale.
