    Description:
      Abstract:
        This dataset is a composite of part or all of the 12 1:250,000 scale quadrangles
        that make up Oklahoma.  The result looks like a geologic map of the State of
        Oklahoma.  But it is only an Oklahoma shaped map clipped from the 1:250,000
        geologic maps.  This is not a new geologic map. No new mapping took place.  
        The geologic information from each quadrangle is available within the composite 
        dataset.

      Purpose:
        This dataset was developed to provide geologic map GIS database of
        Oklahoma for use in future spatial analysis by a variety of users.

      Supplemental_Information:
        This database consists of Arc/Info GIS datasets:
        - ok_geology, the formations and contacts,
        - ok_faults, the faults,
        - ok_folds, the folds and an
        - Xcel spreadsheet for formation correlation

    Data_Set_Credit:
      Joel R. Cederstrand,  prepared and released the original 12 Oklahoma 1:250s and county maps
      as OFR-96-370 to ORF-96-381.  Greg Green, joined the 12 sheets and attributed
      the polygons with text files created by Doug Stoeser and Bill Heran.
      All are with the U.S. Geological Survey.

      Process_Step:
        Process_Description:
          Cederstrand created the digital 1:250,000 versions of the orginal paper maps.
          Stoeser and Heran entered the formation description from the papers maps into
          spread sheet text files.  Green joined these text attributes to the digital
          maps and merged the sheets together.
