Abstract : Subsurface investigation of the Great Marsh indicates that the landward edge of the marsh represents the leading edge of the ongoing marine transgression. Associated with the marsh facies in this Holocene wedge are sediments of lagoonal-tidal creek facies and barrier facies. The spatial relation of these facies appears to be a function of the configuration of the transgression surface. Their distribution in time is a function of the rate of relative sea level rise. Within the marsh facies three subfacies, back barrier, fringing, and broad, can be recognized on the basis of geologic setting and sediment texture. (Author)
