    Description:
      Abstract:
        The Alaska Radiometric Age file is a database of radiometric
        ages of rocks or minerals sampled from Alaska.  The data was
        collected from professional publications and/or received from
        researchers and used by permission.
      Purpose:
        Database of radiometric ages is designed to aid in the research
        of geochronologic information of Alaska rocks and minerals.
        Users should always review the cited publications for more
        complete descriptions of the samples, analyses, and geologic
        interpretation.
      Supplemental_Information:
        The radiometric dates in this data set were collected from
        published sources through 1990(approximately).  The dates were
        compiled over many years and published as a map in the series
        Decade of North American Geology, by the Geological Society of
        America.

    Data_Set_Credit:
      The radiometric age data base has been maintained since the
      mid-1970's.  Compilers include:  F.H. Wilson, Nora Shew, G.D.
      DuBois, and Shawn Dadisman.
  Data_Quality_Information:
    Logical_Consistency_Report:
      Generally, the radiometric ages in the database are as published.
      Some potassium-argon ages have been recalculated using the decay
      constants recommended by the IUGS Subcommission on Geochronology
      in 1976.  Dates that have been recalculated are noted in the
      'Comments' field.
    Completeness_Report:
      The radiometric age database does not include the analytical
      information which is often found in the published sources.  Also, the
      database records do not contain the geologic interpretation of
      the analysis.  Users of this database should always /refer to
      the publications listed in the 'Reference' field for detailed
      information about each analysis.

        Process_Description:
          The Alaska radiometric age file is a compilation of published and other
          released radiometric dates on rocks and minerals of Alaska.  The precision of
          the analyses and the locations of the samples vary widely from the various
          sources.  This compilation has not attempted to interpret the data.  Users of
          this data should always refer to the published sources of the information.

          This database contains for each record:  location, dating method, rock type,
          mineral/phase dated, age (in millions of years), comments, and references.
          The data was imported into Microsoft Access, brought into ArcView3.1 as an
          event theme, and then converted into a shape file.
