DGS Geologic Map No. 8 (Milford-Mispillion River Quadrangles)

Resource Abstract:
The vector data set contains the rock unit polygons for the surficial geology for DGS Geologic Map No. 8 (Milford-Mispillion River Quadrangles). The original Geologic Map Description of the published map follows: This map is the first detailed surficial geologic map in southern Kent and northern Sussex counties. Other maps covering the same or adjacent areas have focused on subsurface geology (Benson and Pickett, 1986), hydrogeology (Talley, 1982), or surficial geology on a regional scale (Jordan, 1964; Owens and Denny, 1979; Ramsey and Schenck, (1990). The purpose of this map is to show the distribution of geologic units found at or near the present land surface. These units are composed of the geologic materials that support agriculture and development, are mined for sand and gravel resources, and are the surface-to-subsurface pathway for water. Initial work in the area of Milford assigned surficial deposits to the Pleistocene (Marine and Rasmussen, 1955) without formational designation. Rasmussen et al. (1960) recognized near-surface units just south of Milford to be the Brandywine Formation, the Beaverdam Sand, and the Walston Silt. Jordan (1964, 1974), assigned these units in the map area to the Columbia Formation. Owens and Minard (1979) extended stratigraphic designations recognized in New Jersey into Delaware and mapped the area as Pensauken Formation (roughly equivalent to the Columbia of Jordan, 1964), with a fringe of deposits labeled as Spring Lake and Van Sciver Lake beds adjacent to Delaware Bay. Owens and Denny (1979) presented a different stratigraphy in a regional map showing the Beaverdam Sand as the dominant surficial deposit with a fringe along Delaware Bay of, from west to east, the Omar Formation and the Ironside Formation. Talley (1982) considered the entire area of the Milford Quadrangle to be covered by the Columbia Formation. Ramsey and Schenck (1990) mapped the Columbia Formation as the major surficial deposit with a younger Pleistocene unit along Delaware Bay given the informal designation of Delaware Bay deposits. The suficial units on this map were recognized on their lithologic characteristics and internal stratigraphy from examination of over 600 lithologic logs from water well and test hole borings as well as outcrop information and shallow soil auger borings. The map units were compared to previously named units to determine the stratigraphic nomenclature. The Columbia Formation is retained in the sense of Jordan (1974). Other previously used names were rejected because of lithologic characteristics different from those units found in the map area. This map includes two new lithostratigraphic units, the Lynch Heights Formation and the Scotts Corner Formation. These units are refinements based on additional geologic information about the Delaware Bay deposits of Ramsey and Schenck (1990). Palynological data proved to be useful in support of differentiation of the two units, especially the stratigraphic distribution of Quercus (oak) species (Johan J. Groot, pers. comm.). Interpretations of climate and vegetation based on the palynology are in the adjoining table. The type section for the Scotts is designated as Lf14-p (adjoining figure). Reference sections are designated as Lf23-x, Mf25-a, and MG33-g. The type section for the Lynch Heights Formation is designated as Lf21-19 (adjoining figure). Reference sections are Le14-18, Le25-12, and boring Lf-53-a. Descriptions of reference sections are available from the Delaware Geological Survey (DGS) upon request and will be published along with other data in support of this map as part of a DGS Report of Investigations. Recognition of subsurface units (the Calvert, Choptank and St. Marys formations) is an extension of the work of Benson et al. (1985), Benson and Pickett (1986), Andres (1986), Groot et al. (1990), Benson (1990), and Ramsey and Schenck (1990). Published (Groot, 1992) and unpublished palynostratigraphic data were used as aids in recognition of these units. Distribution of Holocene deposits of swamp, marsh, and beach were mapped on the basis of vegetation observed on aerial photographs and spot checked in the field for accuracy. Mapped areas are not to be used for wetlands designation as they represent distrib ution of lithologies deposited in environments characterized by vegetation rather than the environments themselves. Offshore distribution of bottom sediment type is based on unpublished data from the Delaware Geological Survey as well as data from Marx (1981), Maley (1981), Strom (1972), and Wethe (1984). Historical shoreline positions are based on data from aerial photographs (1954) and topographic maps (1981).
