  Description:
    Abstract:
      The Yukon Flats basin is an areally extensive forested
      lowland that contains numerous lakes, streams, and marsh
      areas bordered by densely vegetated low rolling hills in
      east central Alaska.  The 1:500,000-scale generalized
      geologic map of the Yukon Flats basin and its
      borderlands is intended to show major geologic features
      that surround the basin.  Geologic (rock) units are
      generalized to highlight significant structural
      boundaries and relationships in order to make the
      general geologic setting of the basin more clearly
      evident and the subsurface basin geology more easily
      inferred.  The map was compiled largely from existing
      geologic maps, most based on field data collected
      between 1948 and 1974.  However, mapping in the
      Livengood, Circle, and parts of the Bettles and Wiseman
      quadrangles was done in the late 1970's and 1980's.
      Data from the Tanana quadrangle was collected as
      recently as 2003.

      This data set is a portion of a statewide geology
      database, which is being compiled by the U.S. Geological
      Survey's National Survey and Analysis (NSA) project,
      whose goal is to compile geologic, geochemical,
      geophysical, and other data.
    Purpose:
      The data set represents part of a systematic effort to
      release geologic map data for the United States in a
      uniform manner.  Geologic data in this series has been
      compiled from a wide variety of sources, published and
      unpublished, ranging from state and regional geologic maps
      to large-scale field mapping.

Data_Quality_Information:
  Attribute_Accuracy:
    Attribute_Accuracy_Report:
      The compiled geology was digitized from a hand drawn
      1:500,000 scale paper map.  Vector and polygon attributes
      were assigned.  The digital data has been checked and the
      geologic map has been technically reviewed and edited.
  Logical_Consistency_Report:
    Each geology coverage is a network coverage containing
    attributed arcs and polygons.  Each polygon has a coded
    attribute designating the mapped geologic unit.  Faults,
    stratigraphic contacts, and other linear features are
    represented as arcs.  When a fault is also a stratigraphic
    contact, only a single arc is present.  Dangle arcs may
    be present (faults, dike, etc.)
  Completeness_Report:
    The complete data set consists of 14 different GIS
    coverages, 12 geology coverages and 2 fold coverages.
    There is also an associated relational database of geologic
    units.  Each coverage has the extent of a 1:250,000 scale
    quadrangle.  A graphic representation of the GIS
    database and a report with complete geologic descriptions is
    provided in .pdf format.

      Process_Description:
        Linework for the geology and folds were digitized and
        incorporated into a geodatabase by Jesse Crews.  The geology
        and folds were converted to coverages with the NSA
        standard data base structure by Keith Labay.  The data was
        divided into 1:250,000 scale quadrangle extents.  Each
        coverage is provided in UTM projection and geographic
        coordinates.  The ARC/Info coverages have been exported to
        an interchange file format, .e00, and also converted to
        ArcView shape files.

  Detailed_Description:
    Entity_Type:
      Entity_Type_Label: polygons
      Entity_Type_Definition:
        Characteristics of the polygon features in the geology
        coverages are coded in the polygon attribute table.  The
        table <cov>.pat includes the following items:  CLASS,
        NSACLASS, NSAMOD, QCLASS (not used), SOURCE, LABEL,
        MIN_AGE, and MAX_AGE.
      Entity_Type_Definition_Source: this data set
    Attribute:
      Attribute_Label: CLASS
      Attribute_Definition:
        CLASS is a positive integer value (4 5 B) item in the
        polygon attribute table.  Values range discontinuously
        from 0 to 4040.  CLASS is a numeric code for the
        geologic unit from Till and others, in prep.  Each CLASS
        matches with a geologic unit label in LABEL and has a
        minimum (MIN_AGE) and maximum (MAX_AGE) range, given in
        million of years (my).

        Each map unit has been assigned an NSACLASS value (4 5
        B).  NSACLASS is a numeric code used for compilation
        geologic mapping for the state of Alaska.  This data set
        represents a generalized map, thus it is possible that a
        geologic unit is made of multiple NSACLASS values.

        NOTE:  Because of the limitations of common GIS fonts,
        the letters "C", "pC", "Mz", "P", "Pz", "Tr" are
        substituted for the standard symbols for "Cambrian",
        "Precambrian", "Mesozoic", "Proterozoic", "Paleozoic",
        and "Triassic." The letters "C" (Carboniferous and
        Cambrian) and "P" (Permian and Proterozoic) have
        multiple age designations, so the user should refer to the
        geologic unit descriptions for the correct geologic age.

    Attribute:
      Attribute_Label: SOURCE
      Attribute_Definition:
        SOURCE is a character (6 8 C) item found in both the
        polygon and arc attribute tables.  The values are
        abbreviated codes representing the original source
        references for the polygon or arc feature.  The format
        for SOURCE is XX###, where XX is a two letter code for the
        1:250,000 scale quadrangle and ### is a three digit number
        (with leading zeros).  All source codes with '001' are
        unspecified sources for water and ice features, often
        paper topographic maps, and DRG or DLG files.

      Entity_Type_Label: arcs
      Entity_Type_Definition:
        Characteristics of the arc features in the geology and fold
        coverages are coded in the arc attribute table.  Table
        <cov>.aat includes the following items:  ARC-CODE,
        ARC-PARA1, and SOURCE.  For explanation of SOURCE, see
        attribute definitions for polygons.
      Entity_Type_Definition_Source: this data set
    Attribute:
      Attribute_Label: ARC-CODE
      Attribute_Definition:
        ARC-CODE is positive integer value (3 3 I) item in the
        arc attribute table.  Values range discontinuously from
        1 to 99.  Values match one-for-one with geologic features
        (such as stratigraphic boundary, fault, etc.)  Some
        ARC-CODE values have additional modifiers in item
        ARC-PARA1.
