  Description:
    Abstract:
      Efforts by a National Cooperative Geologic Mapping Program 
        project to compile the geology of the Edwards aquifer 
        recharge area in south-central Texas have helped to 
        refine the hydrostratigraphy of one of the most 
        permeable and productive carbonate aquifers in the 
        United States.  The complex geology of the recharge area 
        includes lithologic units assignable to the Lower 
        Cretaceous Edwards Group and related units and the 
        Georgetown Formation, which is underlain by the Lower 
        Cretaceous Glen Rose Limestone (lower confining unit) 
        and overlain by the Upper Cretaceous Del Rio Clay, Buda 
        Limestone, and Eagle Ford, Austin, and Taylor and 
        Navarro Groups (upper confining units).  The rock units 
        comprising the Edwards aquifer in the northeastern part 
        of the recharge area (San Marcos platform facies) 
        include the Kainer, Person, and Georgetown Formations.  
        The Kainer and Person Formations are subdivided into 
        seven informal hydrostratigraphic members.  The central 
        part of the recharge area (Devils River trend facies) 
        contains reefal-facies lithologies of the Lower 
        Cretaceous Devils River Formation and the overlying 
        Georgetown Formation.  The western part of the recharge 
        area contains Edwards Group lithologies of deeper water 
        origin (Maverick basin facies) composed of the West 
        Nueces, McKnight, Salmon Peak, and Georgetown 
        Formations.
      Geologic maps of previous workers typically show a vague, 
        dashed boundary separating San Marcos platform and 
        Devils River trend exposures because the Devils River 
        Formation was historically interpreted as discontinuous 
        and lithologically variable.  However, current field 
        studies of the San Marcos platform/Devils River trend 
        transition area reveal that the facies boundary is 
        distinct and follows topographic expression in some 
        areas.  We believe that future work will show that some 
        of the hydrostratigraphic units belonging to the Kainer 
        Formation, particularly the informal basal nodular and 
        dolomitic members, occur in the Devils River trend and 
        deeper water Maverick basin units.  Hydrostratigraphic 
        subdivision of the lower part of the Devils River 
        Formation in Medina and Uvalde Counties and mapping of 
        Maverick basin lithologies in Kinney County are ongoing.
    Purpose: This data set is intended to illustrate the 
      detailed geographic extent of the stratigraphic units and 
      faulting for the Edwards aquifer recharge zone in south-
      central Texas.

Data_Quality_Information:
  Attribute_Accuracy:
    Attribute_Accuracy_Report: Original data were drawn on a 
      1:24,000-scale USGS topographic map by contributing 
      authors.  Attributes have been checked by available 
      authors and reviewers for accuracy and completeness.

  Logical_Consistency_Report: Map elements were visually checked 
    for overshoots, undershoots, duplicate features, and other 
    errors.  ARC/INFO software was used to create topological 
    relations among features.  Features were not duplicated, but 
    coincident lines exist between data layers where 
    appropriate.

  Completeness_Report: Original geologic map units were 
    collected and digitized at appropriate resolution for 
    portrayal at various scales.  The digitized data were then 
    compiled together throughout the study area for a seamless 
    presentation.  Data are complete--No features were 
    eliminated or generalized.  Unit properties are described in 
    the map text.

  Positional_Accuracy:
    Horizontal_Positional_Accuracy:
      Horizontal_Positional_Accuracy_Report: The original data 
        were created by delineating the boundaries on 7.5-minute 
        topographic maps at 1:24,000 scale.  Potential exists 
        for errors in location by the geologist in the field.

    Process_Step:
      Process_Description: Polygons, lines, and points 
        representing geologic and hydrologic features were 
        merged together from exisitng geospatial data sets.  
        Revisions were only made along the Devils River trend 
        where updated mapping occurred.
      Process_Date: 2003

    Process_Step:
      Process_Description: Text map unit descriptors were added 
        to the attribute table of each feature coverage.
      Process_Date: 2003

    Process_Step:
      Process_Description: Draft check plots of the geologic map 
        and explanation were created and submitted for peer 
        review.  Geologists reviewed the plots for conformity 
        with U.S. Geological Survey editorial standards and 
        stratigraphic nomenclature.  Revisions were made to the 
        geospatial database as needed.
      Process_Date: 2003

    Process_Step:
      Process_Description: Coverages were then compiled into a 
        Personal GeoDatabase.
      Process_Date: 2004

    Process_Step:
      Process_Description: The geospatial database files 
        and metadata were quality checked for completeness and 
        consistency.
