Publisher: United States Geological Survey Online_Linkage: http://pubs.usgs.gov/of/2006/1329/ 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.

Native_Data_Set_Environment: Windows_XP, Intel ARC/INFO version 9.1 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 .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 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. >COLUMN ITEM NAME WIDTH OUTPUT TYPE N.DEC ALTERNATE NAME > 1 AREA 8 18 F 5 > 9 PERIMETER 8 18 F 5 > 17 WSPTS# 4 5 B - > 21 WSPTS-ID 4 5 B - > 25 PTTYPE 100 100 C - > 125 SYMBOL 3 3 I - > 128 STRIKE 3 3 I - > 131 DIP 3 3 I - > 134 SOURCE 4 4 I - > >WSPTS.REF: > >COLUMN ITEM NAME WIDTH OUTPUT TYPE N.DEC ALTERNATE NAME > 1 SOURCE 4 4 I - > 5 SCALE 8 8 I - > 13 AUTHORS 200 200 C - > 213 YEAR 4 4 I - > 217 REFERENCE 250 250 C - >Coding of LABEL and DESC attributes in the wsgeo coverage: >LABEL | DESC >Cf | Flathead Sandstone (Middle Cambrian) >Cm | Meagher Limestone (Middle Cambrian) >Cp | Park Shale (Upper and Middle Cambrian) >Cpi | Pilgrim Formation (Upper Cambrian) >Cpmw | Park Shale (Upper and Middle Cambrian), Meagher Limestone (Middle Cambrian), and Wolsey Formation (Middle Cambrian), undivided >Cpp | Pilgrim Formation (Upper Cambrian) and Park Shale (Upper and Lower Cambrian), undivided >Cu | Upper and Middle Cambrian rocks, undivided >Cw | Wolsey Formation (Middle Cambrian) >DCm | Maywood Formation (Upper and Middle Devonian) and locally Upper Cambrian beds >Dj | Jefferson Formation (Upper Devonian) >Du | Upper and Middle Devonian rocks, undivided >EObhd | Biotite hornblende dacite (Eocene) >EObhqm | Biotite hornblende quartz monzonite (Eocene) >EOd | Dacite (Eocene) >EOdi | Biotite diorite (Eocene) >EOg | Granite (Eocene) >EOlwt | Lithic welded tuff (Eocene) >EOm | Monzonite (Eocene) >EOqm | Quartz monzonite (Eocene) >EOrp | Rhyolite porphyry (Eocene) >EOsn | Shonkinite (Eocene) >Jp | Piper Formation (Middle Jurassic) >Js | Swift Formation (Upper Jurassic) >KJm | Morrison Formation (Lower Cretaceous and Jurassic) >KJme | Morrison Formation (Lower Cretaceous and Jurassic) and Ellis Group (Jurassic), undivided >Kcl | Claggett Formation (Upper Cretaceous) >Kcol | Colorado Group, lower part, undivided (Lower Cretaceous) >Ke | Eagle Sandstone (Upper Cretaceous) >Kf | Fall River Formation (Lower Cretaceous) >Kk | Kootenai Formation (Lower Cretaceous) >Km | Mowry Shale (Lower Cretaceous) >Kms | Mowry Shale, Muddy Sandstone Member (Lower Cretaceous) >Kt | Thermopolis Shale, undivided (Late Cretaceous) >Ktc | Telegraph Creek Formation (Upper Cretaceous) >Ktcm | Telegraph Creek Formation (Upper and Lower Cretaceous) and Mowry Shale (Lower Cretaceous), undivided >Ktsh | Thermopolis Shale, Skull Creek shale member (Lower Cretaceous) >Ktss | Thermopolis Shale, sandy member (Lower Cretaceous) >MDt | Three Forks Formation (Lower Mississippian and Upper Devonian) >MIOGf | Fort Logan Formation (Miocene and Oligocene) >MIOGs | Sedimentary rocks, undivided (Miocene and Oligocene) >Mb | Big Snowy Group, undivided (Upper Mississippian) >Mh | Heath Formation (Upper Mississippian) >Mk | Kibbey Formation (Upper Mississippian >Ml | Lodgepole Limestone (Lower Mississippian) >Mlb | Lodgepole Limestone, biohermal limestone (Lower Mississippian) >Mm | Mission Canyon Limestone (Upper and Lower Mississippian) >Mmu | Madison Group, undivided (Upper and Lower Mississippian) >Mo | Otter Formation (Upper Mississippian) >Mt | Tyler Formation, undivided (Upper Mississippian) >Mts | Tyler Formation, sandstone beds in lower and middle parts (Upper Mississippian) >OGEOrb | Rhyolite with breccia blocks of Paleozoic rocks (Oligocene?
