Ramsey, K.W.Tomlinson, J.L.2014-09-262014-09-262014-09http://udspace.udel.edu/handle/19716/13254The geological history of the surficial geologic units in western Sussex County is that of deposition of the Beaverdam Formation and its subsequent modification by erosion and deposition related to the sea-level fluctuations during the Pleistocene. The geology reflects this complex history by the cut and fill geometry of the middle and late Pleistocene deposits into the Beaverdam Formation. The geology is further complicated by periglacial activity that produced dune deposits and Carolina Bays in the map area, which modified the land surface. Mapping was conducted using field maps at a scale of 1:12,000 with 2-ft contours. Stratigraphic boundaries drawn at topographic breaks reflect detailed mapping using contours not shown on this map.en-USBeaverdam FormationCarolina Bay DepositsCat Hill FormationDelmardune depositsHebronHoloceneKent Island FormationLaurelmappingmarsh depositsmodified landPlioceneQuaternary PeriodSharptownSTATEMAPsurficial geologySussex Countyswamp depositsTurtle Branch FormationWalston FormationMiocenePleistoceneTertiary PeriodMap
