  Description:
    Abstract:
      The Puye quadrangle covers an area on the eastern flank of
      the Jemez Mountains, north of Los Alamos and west of Espanola, New
      Mexico.  Most of the quadrangle consists of a dissected plateau that was
      formed on the resistant caprock of the Bandelier Tuff, which was erupted
      from the Valles caldera approximately 1 to 2 million years ago.  Within
      the canyons of the east-flowing streams that eroded this volcanic
      tableland, Miocene and Pliocene fluvial deposits of the Puye Formation and
      Santa Fe Group are exposed beneath the Bandelier Tuff.  These older units
      preserve sand and gravel that were deposited by streams and debris flows
      flowing from source areas located mostly north and northeast of the Puye
      quadrangle.  The landscape of the southeastern part of the quadrangle is
      dominated by the valley of the modern Rio Grande, and by remnants of
      piedmont-slope and river-terrace deposits that formed during various
      stages of incision of the Rio Grande drainage on the landscape.  Landslide
      deposits are common along the steep canyon walls where broad tracts of the
      massive caprock units have slumped toward the canyons on zones of weakness
      in underlying strata, particularly on silt/clay-rich lacustrine beds
      within the Puye Formation.
    Purpose:

      Geology of the Puye quadrangle was mapped as part of the USGS Middle
      Rio Grande Basin project of the late 1990's to explore the geologic
      framework of water resources in the region.  Mapping was conducted in part
      on lands of the Santa Clara Indian Reservation and the San Ildefonso
      Indian Reservation, with the permission of the Indian Nations.

      Portrayal of geologic map units is consistent with the 1:24,000 scale of the map; areas of the map classified as one unit locally include areas of other rock units too small to depict separately.  The descriptions of the rock materials and physical properties are representative of the range of characteristics within the map unit in this quadrangle, but specific characteristics vary from place to place.  Information contained in this database and depicted on the map may provide useful guides to the engineering and resource characteristics of the units, but is typically too generalized for evaluating uses or hazards of specific sites.

    ARC/INFO version 7.1.2

Data_Quality_Information:
  Attribute_Accuracy:
    Attribute_Accuracy_Report:
      These data were checked by the geologist
      who made the original field observations.  Attributes of this geospatial
      data set consist of text identifiers and numeric codes that indicate the
      identity and type of the geologic feature; these codes determine the
      display characteristics of the data in terms of color and symbology.
      Accuracy was established by comparison of check plots to the geologist's
      original map compilation.  Machine-generated lists of unique attribute
      values were checked for spelling errors or inconsistencies.  In addition,
      the report has been reviewed for technical content, as well as for
      conformity with USGS standards for editorial format and stratigraphic
      nomenclature.

  Logical_Consistency_Report:
    Map elements were visually inspected by the
    geologist and by the GIS technician(s) that created the database coverages
    to detect undershoots, overshoots, duplicate features, polygon closure,
    and similar errors.  Automated routines were invoked to detect label and
    attribute errors, sliver polygons, dangling arcs, intersection errors, and
    projection information.  Check plots of the map were reviewed by at least
    two other geologists for consistency with basic geologic principles and
    for general conformity to USGS mapping standards.

  Completeness_Report:
    Data are complete; no features that could be
    accurately represented at map scale were eliminated or generalized.  All
    geospatial database elements are attributed.

  Positional_Accuracy:
    Horizontal_Positional_Accuracy:
      Horizontal_Positional_Accuracy_Report:
        Lines on the map were
        positioned by photointerpretation from 1:40,000-scale aerial photography
        and from direct observation in the field.  Features were digitized by
        scanning the geologic compilation and vectorizing; with geodetic
        rectification, features on the map are estimated to be accurately
        located within about 10 m horizontal dimension.

  Lineage:
    Process_Step:
      Process_Description:
        Polygons, lines, and points representing
        geologic features and data points were digitized from scale-stable
        compilation materials using LT4X and ArcInfo
      Process_Date: 1998
    Process_Step:
      Process_Description:
        Map data were imported to ARC/INFO using the
        GENERATE routine, and topology was built
      Process_Date: 1998
    Process_Step:
      Process_Description:
        Data were imported from spreadsheets containing
        locations of structural data, locations and orientations of paleocurrent
        vectors, sample locations, and the like and converted to coverages.
        Locations and orientations were checked by the geologist on draft plots
      Process_Date: 1999
    Process_Step:
      Process_Description:
        Draft check plots of map elements, along with
        text, correlation diagram, and descriptions of symbols were reviewed by
        peers for technical accuracy and USGS mapping standards.  Revisions were
        made to the database to reflect necessary revisions.
      Process_Date: 2000
    Process_Step:
      Process_Description:
        chief (representing the geologist); draft metadata were reviewed in the
        Team and revised as necessary. Database elements were checked and
        reviewed within the team for topological correctness.
      Process_Date: 2001
    Process_Step:
      Process_Description:
        Digital database files, text files, metadata, and related
        information were reviewed by USGS Central Publications Group and revised
        as necessary.  CPG prepared layout of map sheet elements, adjusted
        colors and patterns, imported standard USGS symbols and marginalia and
        composed the map sheet for print-on-demand distribution.
        Approval of the USGS Director to publish was obtained.
        Final geospatial database files were prepared for web
        distribution, the map sheet image was converted to PDF for the web-
        browse graphic, and all relevant items were posted on the USGS map
        server for public access
