  Description:

    Abstract:
      This data set maps and describes the geology of the Bonners Ferry 30' x
      60' quadrangle, Idaho and Montana.  The bedrock geology of the Bonners
      Ferry quadrangle consists of sedimentary, metamorphic, and granitic rocks
      ranging in age from Middle Proterozoic to Eocene.  Bedrock units include
      rocks of (1) the Middle Proterozoic Belt Supergroup (2) the Middle
      Proterozoic Deer Trail Group, (3) the Late Proterozoic Windermere Group,
      (4) miogeoclinal or shelf facies lower Paleozoic rocks, and (5) Mesozoic
      and Tertiary granitic rocks.

      The Belt Supergroup, a thick sequence of argillite, siltite, quartzite,
      and impure carbonate rocks up to 9,000 m thick, occurs in two
      non-contiguous sequences in the quadrangle: (1) the Clark Fork-Eastport
      Sequence east of the Purcell trench and (2) the Newport Sequence in the
      hanging wall of the Newport Fault.  Only the two lowest Belt formations of
      the Newport Sequence are found in the Bonners Ferry quadrangle, but these
      two units are part of a continuous section, which extends southwestward to
      the town of Newport.

      Belt Supergroup rocks of the Clark Fork-Eastport Sequence are separated
      from those of the  Newport Sequence  by the Newport Fault, Priest River
      Complex, and Purcell Trench Fault.  Some formations of the Belt Supergroup
      show differences in thickness and (or) lithofacies from one sequence to
      the other that are greater than those predicted from an empirical
      depositional model for the distances currently separating the sequences.
      These anomalous thickness and facies differences suggest that there has
      been a net contraction along structures separating the sequences despite
      Eocene extension associated with emplacement of the Priest River Complex.
      In addition to these two Belt sequences, probable Belt rocks are present
      in the Priest River Complex as high metamorphic grade crystalline schist
      and gneiss.

      Northwest of the Newport Sequence of Belt Supergroup is the Deer Trail
      Group, a distinct Middle Proterozoic sequence of argillite, siltite,
      quartzite, and carbonate rocks lithostratigraphically similar to the Belt
      Supergroup, but separated from all Belt Supergroup rocks by the Jumpoff
      Joe Fault.  Rocks of the Deer Trail Group are pervasively phyllitic and
      noticeably more deformed than rocks in the Belt Supergroup sequences.
      Lithostratigraphically the Deer Trail Group is equivalent to part of the
      upper part of the Belt Supergroup.  Differences in lithostratigraphy and
      thickness between individual Deer Trail and Belt units and between the
      Deer Trail and Belt sequences as a whole indicate that they were probably
      much farther apart when they were deposited.

      The Windermere Group is a lithologically varied sequence of volcanic rocks
      and coarse-grained, mostly immature, clastic sedimentary rocks up to 8,000
      m thick.  It is characterized by extreme differences in thickness and
      lithofacies over short distances caused by syndepositional faulting
      associated with initial stages of continental rifting in the Late
      Proterozoic.  Strata of the Windermere Group unconformably overlie only
      the Deer Trail Group, and are nowhere found in depositional contact with
      Belt Supergroup rocks.

      Paleozoic rocks in the Bonners Ferry quadrangle consist of a thin,
      fault-bounded remnant preserved within the Clark Fork-Eastport Belt
      Supergroup Sequence.

      Mesozoic granitic rocks underlie at least 50 percent of the Bonners Ferry
      quadrangle.  They fall into two petrogenetic suites, hornblende-biotite
      plutons and muscovite-biotite (two-mica) plutons, most of which are
      Cretaceous in age.  Both suites are represented in the mid-crustal Priest
      River Complex and in the higher level plutons that flank the complex; by
      far the majority of the Priest River Complex are Cretaceous, two-mica
      bodies.

      Tertiary rocks are restricted to a single small stock, numerous hypabyssal
      dikes that are too small to show at the scale of the map, and to
      cataclastic rocks related to the Newport Fault.

      Quaternary deposits include unconsolidated to poorly consolidated glacial,
      alluvial, glacial-lacustrine, and landslide units.

      Created using Environmental Systems Research Institute's ARC/INFO
      software, the data base consists of the following items: (1) a map
      coverage containing geologic faults, contacts and units, (2) a point
      coverage containing site-specific geologic structural data, (3) a line and
      point coverage containing structural data (fold axes) along with geologic
      line ornamentation, (4) a coverage containing cartographic elements
      (annotation), (5) four coverages derived from 1:100,000 Digital Line
      Graphs (DLG); topography, hydrography, and cultural data contained in two
      transportation coverages, road and rail, and (6) attribute and lookup
      tables for geologic units (polygons), contacts and faults (arcs), and
      site-specific data (points).  In addition, the data set includes the
      following graphic and text products: (1) A PostScript graphic plot-file
      containing the geologic map, topography, cultural data, a list of Map
      Units (DMU), modal diagrams for granitic rocks, an index map, a regional
      geologic and structure map, and a key for point and line symbols; (2) PDF
      files of the Readme, Description of Map Units (DMU) including a discussion
      of the geologic framework, (3) map-sheet and (4) this metadata file.

      The geologic map database contains original U.S. Geological Survey data
      generated by detailed field observation and by interpretation of aerial
      photographs. The map was compiled from geologic maps of eight 1:48,000 15'
      quadrangle blocks, each of which was made by mosaicking and reducing the
      four constituent 7.5' quadrangles.  These 15' quadrangle blocks were
      mapped chiefly at 1:24,000 scale, but the detail of the mapping was
      governed by the intention that it was to be compiled at 1:48,000 scale.
      The compilation at 1:100,000 scale entailed necessary simplification in
      some areas and combining of some geologic units.  Overall, however,
      despite a greater than two times reduction in scale, most geologic detail
      found on the 1:48,000 maps is retained on the 1:100,000 map.  Geologic
      contacts across boundaries of the eight constituent quadrangles required
      minor adjustments, but none significant at the final 1:100,000 scale.

      The geologic map was compiled on a base-stable cronoflex copy of the
      Bonners Ferry 30' X 60' topographic base and then scribed.  The scribe
      guide was used to make a 0.007 mil-thick blackline clear-film, which was
      scanned at 1200 DPI by Optronics Specialty Company, Northridge,
      California.  This image was converted to vector and polygon GIS layers and
      minimally attributed by Optronics Specialty Company.  Minor hand-digitized
      additions were made at the USGS.  Lines, points, and polygons were
      subsequently edited at the USGS by using standard ARC/INFO commands.
      Digitizing and editing artifacts significant enough to display at a scale
      of 1:100,000 were corrected. Within the database, geologic contacts are
      represented as lines (arcs), geologic units as polygons, and site-specific
      data as points.  Polygon, arc, and point attribute tables (.pat, .aat, and
      .pat, respectively) uniquely identify each geologic datum.
    Purpose:
      The data set for the Bonners Ferry 30' X 60' quadrangle has been jointly
      prepared by the U.S. Geological Survey National Cooperative Geologic
      Mapping Program, the Mineral Resource Program, and by the Southern
      California Areal Mapping Project (SCAMP), as part of an ongoing effort to
      utilize a Geographical Information System (GIS) format to create regional
      digital geologic databases.  These regional databases are being developed
      as contributions to the National Geologic Map Data Base of the National
      Cooperative Geologic Mapping Program.

      The digital geologic map database for the Bonners Ferry 30' X 60'
      quadrangle has been created as a general-purpose data set that is
      applicable to other land-related investigations in the earth and biological
      sciences.  For example, it can be used for mineral resource evaluation
      studies, animal and plant habitat studies, and soil studies in the Idaho
      Panhandle National Forest.  The database is not suitable for site-specific
      geologic evaluations.

  Use_Constraints:
    The Bonners Ferry 30' x 60' geologic-map database should be used to
    evaluate and understand the geologic character of the Bonners Ferry 30' x
    60' quadrangle as a whole.  The data should not be used for purposes of
    site-specific land-use planning or site-specific geologic evaluations.
    The database is sufficiently detailed to identify and characterize
    geologic materials and structures.  However, it is not sufficiently
    detailed for site-specific determinations.

    Use of this digital geologic-map database should not violate the spatial
    resolution of the data.  Although the digital form of the data removes the
    constraint imposed by the scale of a paper map, the detail and accuracy
    inherent in map scale are also present in the digital data.  The fact that
    this database was compiled and edited at a scale of 1:100,000 means that
    higher resolution information may not have been uniformly retained in the
    dataset.  Plotting at scales larger than 1:100,000 will not yield greater
    real detail, although it may reveal fine-scale irregularities below the
    intended resolution of the database.  Similarly, although higher
    resolution data is incorporated in most of the map, the resolution of the
    combined output will be limited by the lower resolution.

Data_Quality_Information:
  Attribute_Accuracy:
    Attribute_Accuracy_Report:
      Geologic-map units in the Bonners Ferry quadrangle database were described
      using standard field methods.  Consistent with these methods, the database
      author has assigned standard geologic attributes to geologic lines,
      points, and polygons identified in the database.

      Nation-wide geologic-map accuracy standards have not been developed and
      adopted by the U.S. Geological Survey and other earth-science entities.
      Until such standards are adopted, SCAMP-related projects have developed
      internal map-accuracy standards for 1:100,000-scale geologic maps produced
      under the projects.

      Geologic lines and points on 1:100,000 scale geologic maps are judged to
      meet SCAMP's internal map-accuracy standards if they are located to within
      +/-50 meters, relative to topographic or cultural features on the base
      map.  On any derivative geologic-map plot, line data for faults that are
      judged to meet the SCAMP internal map-accuracy standard are denoted by
      solid lines; line data that may not meet the SCAMP internal map-accuracy
      standard are denoted by dashed or dotted lines.  All non-fault contacts
      are represented by solid lines.  Because many of the contacts in the
      Priest River Complex are highly gradational, they may not be located to
      within +/-50m.  There is no cartographic device for denoting the
      map-accuracy for geologic-point data (eg.  symbols representing bedding,
      foliation, lineations, etc.).

  Logical_Consistency_Report:
    Polygon and chain-node topology present.

    The areal extent of the map is represented digitally by an appropriately
    projected (UTM projection), mathematically generated box.  Consequently,
    polygons intersecting the lines that comprise the map boundary are closed
    by that boundary.  Polygons internal to the map boundary are completely
    enclosed by line segments which are themselves a set of sequentially
    numbered coordinate pairs.  Point data are represented by coordinate pairs.

  Completeness_Report:
    The geologic map and digital database of the Bonners Ferry 30'x 60'
    quadrangle contain new data that have been subjected to rigorous review and
    are a substantially complete representation of the current state of
    knowledge concerning the geology of the area.

        with base-stable source data.

  Overview_Description:
    Entity_and_Attribute_Overview:
      Version 1.0 of the Bonners Ferry 30' x 60' quadrangle comprises eight
      ARC/INFO coverages, of which three contain geologic data, one contains
      cartographic features, and four provide base-map, DLG-derived, reference
      data: bferry_geo (geology), bferry_pts (structural point data), bferry_fa
      (fold axes and geologic line ornamentation), and bferry_anno (geologic
      unit annotation, label leaders, locality names), hypso (hypsography),
      hydro (hydrography), trans_rds and trans_rail (transportation and cultural
      data).  Line and point identities are recorded in the .aat and .pat tables
      using a system of identity codes.  Six lookup tables contain additional
      feature attribution: bferry_geo.ru (rock unit data), bferry.pattern
      (pattern overlays for drawing specific units),  bferry.con (geologic
      contacts data), bferry.str (fault and fold axis data), bferry.att
      (structural point data), and bferry.orn (geologic line ornamentation).
      Two INFO tables, lines.rel and points.rel provide a full description of
      each of the geologic line and point codes in the database.  A full source
      citation is provided in the Entity_and Attribute_Detail_Citation section
      of this metadata document. However, many of the line and point
