  Description:
    Abstract:
      This is a shapefile and ARC/INFO point coverage of coal
      geochemistry in the Colorado Plateau. This GIS layer was
      created from the U.S. Geological Survey's USCHEM database
      for the Colorado Plateau coal assessment.
    Purpose:
      The Nation's coal resources are being reassessed by the
      USGS. A fundamental component of this assessment work is to
      compile digital geologic and geographic data into a
      Geographic Information System (GIS). Use of this GIS allowed
      for the spatial integration of data layers. This resulted in
      the ability to display, analyze, and query data to answer
      complex geo-spatial questions concerning coal geology and
      resource occurrence.

      Process_Description:
        Geochemistry data for the Colorado Plateau assessment
        consists of geologic, stratigraphic, and chemical
        information collected between 1974 and 1990. The data
        provided are representative of the coal beds sampled
        and were carefully selected to provide a regional view
        of the overall coal quality. Samples for the Colorado
        Plateau study are primarily drill core or mine.
        However, when insufficient data was available to
        adequately evaluate an individual coal field or to
        provide a regional view of the quality of the coal
        field, samples from drill cuttings and outcrops were
        included. This GIS layer was created from the U.S.
        Geological Survey's USCHEM database. Samples retrieved
        are less than 50% ash yield, Cretaceous age, and within
        the Colorado Plateau study area (Colorado, Utah,
        Arizona, and New Mexico). All samples were edited for
        geological content and updated to reflect new coal bed
        correlations and formation changes. This data set is
        therefore a modified subset of the USCHEM database.
        This data is stored as an ASCII text file
        (coplateau.txt) and was converted to an ArcView shape
        file for this project.
