  Description:
    Abstract: 
      The geologic map of the White Sulphur Springs quadrangle, scale 
        1:100,000, was made as part of the Montana Investigations Project 
        to provide new information on the stratigraphy, structure, and 
        geologic history of the geologically complex area in west-central 
        Montana.  The quadrangle encompasses about 4,235 km2 (1,635 mi2), 
        across part of the Smith River basin, the west end of the Little 
        Belt Mountains, the Castle Mountains, and the upper parts of the 
        basins of the North Forks of the Smith and Musselshell Rivers and 
        the Judith River.  Geologically the quadrangle extends across the 
        eastern part of the Helena structural salient in the Rocky 
        Mountain thrust belt, a segment of the Lewis and Clark tectonic 
        zone, west end of the ancestral central Montana uplift, and the
        southwest edge of the Judith basin.
      Rocks and sediments in the White Sulphur Springs quadrangle are 
        assigned to 88 map units on the basis of rock or sediment type 
        and age.  The oldest rock exposed is Neoarchean diorite that is 
        infolded with Paleoproterozoic metamorphic rocks including 
        gneiss, diorite, granite, amphibolite, schist, and mixed 
        metamorphic rock types.  A thick succession of the 
        Mesoproterozoic Belt Supergroup unconformably overlies the 
        metamorphic rocks and, in turn, is overlain unconformably by 
        Phanerozoic sedimentary and volcanic rocks.  Across most of the 
        quadrangle, the pre-Tertiary stratigraphic succession is intruded 
        by Eocene dikes, sills, and plutons.  The central part of the 
        Little Belt Mountains is generally underlain by laccoliths and 
        sheet-like bodies of quartz monzonite or dacite.  Oligocene 
        andesitic basalt flows in the western and southern part of the 
        quadrangle document both the configuration of the late Eocene 
        erosional surfaces and the extent of extensional faulting younger 
        than early Oligocene in the area.
      Pliocene, Miocene, and Oligocene strata, mapped as 11 units, 
        consist generally of interbedded sand, gravel, and tuffaceous 
        sedimentary rock.  Quaternary and Quaternary-Tertiary sediments 
        rest across the older Cenozoic deposits and across all older 
        rocks.  The Quaternary and Quaternary-Tertiary deposits generally are 
        gravels that mantle broad erosional surfaces on the flanks of the 
        mountains, gravels in stream channels, and colluvium and 
        landslide deposits on hill sides.  Glacial deposits, representing 
        at least two stages of glaciation, are present in the northern 
        part of the Little Belt Mountains.
      The geologic structure of much of the northwest part of the 
        quadrangle is a broad uplift, in the core of which the 
        Paleoproterozoic and Neoarchean metamorphic rocks are exposed.  
        Down plunge to the east, the succession of Phanerozoic 
        sedimentary rocks define an east-trending arch, cored locally by 
        Mesoproterozoic strata of the Belt Supergroup.  The north flank 
        of the arch dips steeply north as a monocline.  Stratigraphic 
        relations among Mississippian, Pennsylvanian, and Jurassic strata 
        document the recurrent uplift and erosion on that north flank.  
        The broader arch of the Little Belt Mountains reflects the west 
        plunge of the ancestral Central Montana uplift.
      The eastern extension of the Lewis and Clark tectonic zone is 
        exposed in the southern half of the quadrangle where the Volcano 
        Valley fault zone curves from west to southeast as a reverse 
        fault along which the latest movement is up on the south side.  
        The fault zone ends in an anticline in the south-central margin 
        of the quadrangle.  Stratigraphic overlap of Phanerozoic strata 
        over the truncated edges of Mesoproterozoic units documents that 
        the area of the eastern terminus of the fault zone was 
        tectonically recurrently active.
      Northeast trending strike-slip faults displace Mesoproterozoic 
        rocks in the northwest and south-central parts of the quadrangle.  
        Several of those faults are overlain unconformably by the Middle 
        Cambrian Flathead Sandstone.  Other north-east and west-trending 
        faults across the central part of the quadrangle are intruded by 
        middle Eocene plutons.  Younger faults displace rocks in the 
        west-central and southwest parts of the quadrangle.  The younger 
        faults dropped down the Smith River Valley to the west and 
        control the traces of Sheep Creek and Tenderfoot Creeks in the 
        northwest part of the quadrangle.

    Purpose: The preliminary geologic map of the White Sulphur Springs 30 x 
      60 quadrangle, west-central Montana summarizes new and selected 
      existing geologic information for public use and use by Federal, 
      State, and local governmental agencies for land use planning, 
      including assessment of natural resources, natural hazards and 
      recreational potential, and for land use management.  The map 
      provides an interpretation of the complex geology, recurrent 
      tectonism and volcanism, and terrain at the junction between the 
      Montana disturbed belt and the more stable continental crust.  
      The map defines relations among the west end of the central 
      Montana uplift, the Lewis and Clark tectonic zone, and the Rocky 
      Mountain thrust belt in the Helena salient.  The geologic map is 
      an element in the program of the State of Montana and the U.S. 
      Geological Survey to produce 1:100,000-scale geologic map 
      coverage for the entire State.

  Data_Set_Credit: Theodore Brandt, U.S. Geological Survey, served as primary 
    author of the GIS database and produced the map layout.

Data_Quality_Information:
  Attribute_Accuracy:
    Attribute_Accuracy_Report: Data were entered and checked by the geologist
      that made the field observations and compilation.  The attributes of this
      geospatial data set consist of text identifiers and numeric codes that
      indicate the identity of the geologic unit or type of geologic feature,
      and determine how each feature is colored or symbolized.  To check
      the attribute accuracy, a color check plot was visually compared to the
      geologist's original compilation.  Discrepancies between the digital
      geospatial data set and the original analog compilation were corrected
      as needed.  Machine-created listings of unique attribute values were used
      to identify spelling errors or other inconsistencies, and corrections were
      made as needed.  This map has been thoroughly reviewed for conformity with
      U.S. Geological Survey editorial standards and stratigraphic nomenclature.

  Logical_Consistency_Report: Map elements were visually checked for overshoots, 
    undershoots, duplicate features, polygon closure, and other errors by the 
    authors and by the GIS technician(s) who created the digital database.  
    Automated (ArcInfo) routines were also used to check the databases for 
    polygon label errors, line or point attribution errors, sliver polygons, 
    dangling arcs, intersection errors, and projection information.  Check plots 
    of the map were reviewed by another geologist and cartographer for 
    consistency with basic geologic principles and general conformity to USGS 
    mapping standards.

  Completeness_Report: Data are preliminary.  No features that could be 
    accurately represented at a scale of 1:100,000 were eliminated or 
    generalized.  The smallest area represented is approximately 95 square 
    meters.  All geospatial database elements are attributed.

  Positional_Accuracy:
    Horizontal_Positional_Accuracy:
      Horizontal_Positional_Accuracy_Report: 
        Most digitized positions on the map that depict distinct contacts 
          between rock formations in the field are estimated to be within 
          50 m of the actual contact on the land in most instances.  Boundaries 
          (lines) between Quaternary units (for example, terrace gravels) that 
          correspond closely to distinct edges of landforms (for example, river 
          terraces) are of comparable accuracy.  Boundaries (lines) between some 
          Quaternary units, such as eolian deposits and broad alluvial aprons, 
          are approximately located within an indefinite gradational zone 
          between them.  Horizontal positional accuracy is tested by visual 
          comparison of hard copy test plots to source maps or comparing 
          locations of data on a computer monitor to other data layers in the 
          same geographic area.  The database contains no elevation data.  
          Accuracy of these digital data indirectly depends on accuracy of the 
          base maps on which the original source geologic maps were compiled.  
          These base maps were made by the U.S. Geological Survey, which 
          routinely checks them for compliance with the National Map Accuracy 
          Standards.

      DATABASE STRUCTURE - ArcInfo ====================================
      This GIS database includes related look-up tables, which store 
        detailed attribute information.  This database structure is more fully 
        described in USGS OFR 99-438.  The GIS database structure used in the 
        database includes symbol and pattern items in coverage point, polygon 
        (PAT), and arc (AAT) attribute tables for user convenience.  ArcInfo 
        relates for each coverage are saved in a file named <covername>.rel.  
        Use the RELATE command with the restore argument at the arc prompt to 
        make the relates active.  Alternatively, in ArcTools, use the Relate 
        environment: open dialog in the Manage - Relates flyout menu under the 
        ArcTools menu to make the relates active.

      wsgeo coverage:  Contains all contact lines and label points for each 
        geologic polygon.  In the .pat INFO file the SOURCE item provides a 
        numeric code used to identify the data source for the rock unit.  
        Complete references for the sources listed are listed in the wsgeo.ref 
        file.  The LABEL item indicates the rock unit label (abbreviation) used 
        to label unit on map.  The MLABEL item indicates the rock unit label 
        from GeoAge version 1.2 font, using geologic age letter symbols 
        associated with the age of the lithologic units (for example: Triassic, 
        Pennsylvanian, Cambrian).  The DESC item defines formal or informal unit 
        name.  The SYMBOL item contains the shadeset symbol number used by 
        ArcInfo to plot a filled/shaded polygon.  The symbol numbers in this 
        item refer to the wpgcmykg.shd shadeset included with the dataset.  The 
        PATTERN item contains the pattern number used in the published version 
        of the map.  Patterns that correspond with the pattern numbers are 
        displayed in USGS OFR 99-430.  There is no ArcInfo shadeset that 
        corresponds to these patterns.  These patterns are not shown in the 
        browse graphic of the map, but will be shown in the planned SIM report.

      In the wsgeo.aat INFO file, the LINECODE item provides a numeric code 
        used to identify type of linear feature.  Linecodes less than 100 are 
        used for contacts and boundaries that are described in the wsgeo.con 
        file.  Linecodes greater than 100 are used for structures that are 
        described in the wsgeo.str file.  The NAME item lists the name given to
        the structural feature.  The SOURCE item lists the numeric code used to 
        identify the data source for the linear feature.  The SYMBOL item lists 
        the line symbol number used by ArcInfo to plot the line (symbol numbers 
        refer to the geol_sfo.lin lineset).  Complete references for the sources 
        are listed in the wsgeo.ref file.  Related look-up table files are 
        wsgeo.con, wsgeo.str, and wsgeo.ref.  In the wsgeo.con INFO file, 
        the LINECODE item indicates the numeric code (a value less than 100) 
        used to identify type of contact or boundary.  The SYMBOL item lists the 
        line symbol number used by ArcInfo to plot the line (symbol numbers 
        refer to the geol_sfo.lin lineset included with the dataset).  The TYPE 
        item lists the major type of line (for example, contact, State 
        boundaries, lines of latitude and longitude used for neatlines).  The 
        MODIFIER item lists the line type modifier (that is, approximate, 
        concealed, or gradational).  No entry implies 'known.'  The CERTAINTY 
        item lists the degree of certainty of contact or boundary (that is, 
        inferred or uncertain).  No entry implies 'certain.'  The DESC item 
        lists the written description or explanation of the contact or boundary.  
        In the wsgeo.str INFO file, the LINECODE item indicates the numeric 
        code (a value greater than 100) used to identify type of structure.  The 
        SYMBOL item lists the line symbol number used by ArcInfo to plot the 
        line (symbol numbers refer to the geol_sfo.lin lineset included with the 
        dataset).  The TYPE item lists the major type of line (for example, 
        fault or fold-axis).  The HORIZONTAL item refers to the type of 
        horizontal fault movement (for example, left-lateral or right-lateral).  
        No entry implies 'unknown' or no strike-slip movement.  The VERTICAL 
        item refers to the type of vertical fault movement (for example, 
        normal).  No entry implies 'unknown' or no dip-slip movement.  The FOLD 
        item refers to the type of fold (for example, anticline or syncline).  
        The PLUNGE item refers to the type of plunge on fold (that is, 
        horizontal, plunging, plunging in, or plunging out).  The ACCURACY item 
        refers to the line type modifier indicating degree of accuracy (that 
        is, approximately located, concealed, gradational).  No entry implies 
        'certain.'  The CERTAINTY item lists the degree of certainty of 
        structure (that is, inferred, uncertain).  No entry implies 'certain.'  
        The DESC item lists the written description or explanation of the 
        structure.

      wspts coverage:  Contains points recording site-specific observations and 
        measurements, such as strike and dip of bedding

      In the wspts.pat INFO file, the PTTYPE item lists the type of point 
        symbol (for example, strike and of inclined bedding).  The SYMBOL item 
        lists the marker symbol used by ArcInfo to identify the type of 
        structural map symbol(symbol numbers refer to the geoscamp2.mrk 
        markerset).  The STRIKE item contains the strike of bedding as well as 
        trend of fold axis, where applicable.  Strike is an azimuthal angle.  
        Measured in degrees from 0 to 360 in a clockwise direction from North, 
        the STRIKE value also specifies the dip direction, where the dip 
        direction is 90 degrees clockwise relative to the STRIKE.  The DIP item 
        contains the dip of bedding as well as plunge angles, where applicable.  
        This value is an angle measured (in degrees from 0 to 90) down from the 
        horizontal; thus a horizontal dip is 0 degrees and a vertical dip is 90 
        degrees.  In the wspts.ref INFO file, the SOURCE item lists the numeric 
        code used to identify the data source.  The SCALE item lists the scale 
        of the source map.  (This value is the denominator of the proportional 
        fraction that identifies the scale of the map that was digitized or 
        scanned to produce the digital map.)  The AUTHORS item lists the 
        author(s) or compiler(s) of source map entered as last name, first name 
        or initial, and middle initial.  The YEAR item lists the source (map) 
        publication date.  The REFERENCE item lists the remainder of the 
        reference in USGS reference format.
