  Description:
    Abstract: Approximate subsurface geologic unit locations and geometry, displayed in map cross section
    Purpose: To display geologic units in geologic map cross section
    Supplemental_Information: The bedrock feature class of the geologic map of the Mason and Dixon 7.5-minute quadrangle, Washington County, Maryland (1:24,000 scale; 1 inch = 2,000 feet).  Geologic field mapping in the quadrangle was conducted in 2011-2013 by David K. Brezinski. This map area is included in an investigation of karst development in the Hagerstown Valley.  The karst investigation was conducted by the Maryland Geological Survey as part of a collaborative effort with the Maryland State Highway Administration and the USGS STATEMAP component of the National Cooperative Geologic Mapping Program. The geologic components were originally drafted onto stable-base material using the corresponding U.S. Geological Survey (USGS) topographic quadrangle map as a base (1:24,000 scale).  The digital geologic map was developed for geographic information systems (GIS) using ESRI's ArcGIS Desktop software.  The geologic map is produced in the Maryland State Plane Coordinate System (Lambert conformal conic projection, NAD83, meters) (1:24000 scale). The components of the digital geologic map are divided into separate feature classes for bedrock geology, surficial Quaternary deposits, structural line features (e.g., faults), structural point features (e.g., bedding measurements), and geologic cross-section elements.  Digital base map layers were derived from USGS topographic map for this quadrangle and other sources (see supplemental_information). Digital feature attributes for the bedrock geology file include unit labels, unit names and abbreviated lithologic descriptions for the coverage polygons and certainty and general type of geologic contacts for the coverage arcs.

  Attribute_Accuracy:
    Attribute_Accuracy_Report: Location and geometry of cross-section units are estimated by the stratigrapher.  They represent the theoretical geometry of geologic units at-depth, based on surface exposure of geologic features.  The interpretation is conjectural and may not represent actual subsurface conditions.
  Logical_Consistency_Report: This representation of subsurface geologic units is based on the at-depth stratigraphic interpretation of geologic structures identified at the lands surface, and, where available, subsurface data such as well logs and seismic data.  Generally, subsurface data is too sparse in this area to allow for fully accurate representations of subsurface structures.  Therefore this geometry represents the stratigrapher's interpretation of the available data.  The graphic data has been tested for consistency through the application of ArcGIS topologic testing.  Polylines were tested to a 0.001 tolerance for overlap or gaps between line features and adjacent geologic formation polygons.
  Completeness_Report: Omissions in geologic unit data would be due primarily to lack of subsurface data or hidden or undiscovered surface units.  The stratigrapher has employed accepted standard procedures and due diligence to ensure the construction of reasonable geologic models.  Updates may occur as needed or as additional data become available. Check MGS website for version number or contact MGS Publications Office.
  Positional_Accuracy:
    Horizontal_Positional_Accuracy:
      Horizontal_Positional_Accuracy_Report: Location and geometry of geologic units are estimated by the stratigrapher.  They represent the theoretical geometry of geologic faults at-depth, based on surface exposure of geologic features.  The interpretation is conjectural and may not  represent actual subsurface conditions.
