B10, 74 p., https://doi.org//10.3133/tm11B10. The purpose of this data release is to provide Geologic Map Schema (GeMS)-compliant data for the geologic map of Precambrian metasedimentary rocks of the Medicine Bow Mountains, Albany and Carbon Counties, Wyoming. Development and publication of modern GIS data for geologic maps is foundational and high-priority to the USGS Mineral Resources Program (MRP) to facilitate on-going research and other activities pertaining to critical mineral deposits as well as to other geologic and geophysical mapping efforts, petrologic studies, and mineral resource assessments. MedicineBowMtns_I-2280.gdb is a composite geodataset that conforms to "GeMS (Geologic Map Schema) - A standard format for the digital publication of geologic maps," available at http://ngmdb.usgs.gov/Info/standards/GeMS/. A shapefile version of the dataset is also available. It consists of shapefiles, DBF files, and delimited text files and retains all information in the native geodatabase, but some programming will likely be necessary to assemble these components into usable formats. The Esri file geodatabase (MedicineBowMtns_I-2280.gdb) contains the following elements: --GeologicMap: feature dataset (subdirectory) containing the following feature classes (GIS layers): ----CartographicLines: line layer representing cartographic constructs that have no real-world physical existence, such as cross section lines. ----ContactsAndFaults: line layer representing locations of contacts and faults. ----DataSourcePolys: polygon layer representing the spatial extent of data sources and (or) references used within the map boundary. ----GeologicLines: line layer representing the locations of dikes, fold axes, and other linear features. ----MapUnitPolys: polygon layer representing the distribution of geologic map units. ----OrientationPoints: point layer representing structure measurements, such as bedding attitudes, foliation attitudes, and small folds. --DataSources: table that lists sources and (or) references used to derive spatial features (points, lines, polygons) and attribute information. --DescriptionOfMapUnits: table of map unit descriptions derived from the collar of the geologic map or geologic map pamphlet. The hierarchical order of map units is coded in the HierarchyKey field. --GeoMaterialDict: table that defines and lists lithology terms in hierarchical order used in the GeoMaterial field of the DescriptionOfMapUnits table. The standardized vocabulary is available in Appendix 1 of the GeMS documentation. --Glossary: table that defines and lists sources of terms used in the database.

Lakewood CO 80225 US 303-236-1921 303-236-3200 jhorton@usgs.gov Work was accomplished by the U.S. Geological Survey Geology, Geophysics, and Geochemistry Science Center (GGGSC) with support from the Mineral Resources Program (MRP) and the National Geologic Map Database (NGMDB). Microsoft Windows 10 Enterprise, Version 1909 (Build 18363); Esri ArcGIS Pro 3.4.3 Unique values in attribute fields were checked through frequency analyses. The unique values in each attribute field were reviewed and checked for spelling, consistency of terms, accuracy, adherence to established vocabularies, and completeness. Text terms and values entered by USGS authors were reviewed and verified. Confidence that a feature exists and confidence that a feature is correctly identified are described in per-feature attributes ExistenceConfidence and IdentityConfidence. GIS layer and attribute information were extracted and digitized directly into the GeMS database structure. Attribute values were modified for consistency with GeMS terminology. Topology tests were conducted on polygon and line feature classes to ensure spatial integrity of the data. Polygon, line, and point features were digitized from the printed map (Houston and Karlstrom, 1992) and quality assured for completeness. Textual information from the original printed map 'Description of Map Units' section (Houston and Karlstrom, 1992) was transcribed into the DescriptionOfMapUnits table. Horizontal accuracy of point, line, and polygon features is dependent on the accuracy of the 1:50,000 scale source map. Map publication techniques employed in 1992 resulted in variable line quality and accuracy. Estimated accuracy of horizontal location, provided on a per-feature basis in the attribute field LocationConfidenceMeters in GeMS, was assigned a value of -9 indicating unknown. Vertical accuracy testing does not apply to this dataset. R.S. Houston K.E.

The printed map was obtained from the National Geologic Map Database (NGMDB) and georeferenced by the USGS using evenly distributed control points. The data were captured by staff at East View Geospatial by heads-up digitizing of the georeferenced version of the Houston and Karlstrom (1992) printed geologic map and saved as an Esri file geodatabase in GeMS format. 2022 Attributes were populated to conform to the Geologic Map Schema (GeMS) standard for geologic map publications (USGS NCGMP, 2020). Definitions of these values are derived from the printed map (Houston and Karlstrom, 1992), GeMS (USGS NCGMP, 2020), and from the Glossary of Geology (Neuendorf and others, 2011). Map unit colors were matched to the original publication as best possible and are provided as RGB values in the AreaFillRGB field of the DescriptionOfMapUnits table. Map unit colors are also provided in the custom Esri Style file. Geologic map symbolization was also matched to the original publication as best possible using the FGDC Digital Cartographic Standard for Geologic Map Symbolization (FGDC, 2006). These values are provided in the Symbol attribute fields and the included Esri Style file. Topology tests were conducted on polygon and line feature classes to ensure spatial integrity of the data. The geodatabase was confirmed to be GeMS compliant using GeMS validation tools.

Commonly structured according to one or more accepted traditions (for example, lithology, thickness, color, weathering and outcrop characteristics, distinguishing features, genesis, age constraints). USGS NCGMP, 2020 Example of values from the DescriptionOfMapUnits table: "Amphibole and biotite rich; interpreted to be graywacke" Examples of values from the ContactsAndFaults feature class: "contact, certain" or "fault, normal, Precambrian age, certain" DescriptionOfMapUnits_ID [DMapUns_ID] (DescriptionOfMapUnits) Unique alpha-numeric value assigned to each feature (primary key). USGS NCGMP, 2020 Values are unique within this database. Example of values: "DMU01" DescriptionSourceID [DesSrcID] (DescriptionofMapUnits) Source(s) of map unit description; alpha-numeric value used to link to DataSources table (foreign key).

ExistenceConfidence [ExiConf] (ContactsAndFaults, GeologicLines) Confidence that feature exists. USGS NCGMP, 2020 certain Identity of a feature can be determined using relevant observations and scientific judgment; therefore, one can be reasonably confident in the credibility of this interpretation. USGS NCGMP, 2020 questionable Identity of a feature cannot be determined using relevant observations and scientific judgment; therefore, one cannot be reasonably confident in the credibility of this interpretation. For example, IdentityConfidence = questionable is appropriate when a geologist reasons "I can see some kind of planar feature that separates map units in this outcrop, but I cannot be certain if it is a contact or a fault." USGS NCGMP, 2020 unspecified Used for the boundary of a map where no confidence is specified. USGS NCGMP, 2020 FullName (DescriptionOfMapUnits) Name of map unit including identification of containing higher rank unit(s). USGS NCGMP, 2020 Example of values: "Bow Quartzite of the Phantom Lake Metamorphic Suite" GeologicLines_ID [GeoLin_ID] (GeologicLines) Unique alpha-numeric value assigned to each feature (primary key). USGS NCGMP, 2020 Values are unique within this database. Example of values: "GEL001" GeoMaterial [GeoMat] (DescriptionOfMapUnits, GeoMaterialDict) Categorization of map unit based on lithologic and genetic character; term selected from NGMDB standard term list defined in Appendix 1 of GeMS documentation. USGS NCGMP, 2020 Examples of values: "----Quartzite" or "----Medium and high-grade regional metamorphic rock, of unspecified origin" GeoMaterialConfidence [GeoMatConf] (DescriptionOfMapUnits) Describes appropriateness of GeoMaterial term for describing the map unit. USGS NCGMP, 2020 High The term and definition adequately characterize the overall lithologic nature of rocks and sediments in the map unit. Regarding the subjective term "adequately characterize," we refer to context and objectives of this classification as described in the GeMS documentation. USGS NCGMP, 2020 Medium The term and definition generally characterize the overall lithology of the map unit, but there are one or more significant minor lithologies that are not adequately described by the selected term. USGS NCGMP, 2020 Low The overall lithology of this map unit is not adequately classifiable using this list of terms and definitions, but the term selected is the best available. Or this map unit is insufficiently known to confidently assign a GeoMaterial term. USGS NCGMP, 2020 Glossary_ID [Glo_ID] (Glossary) Unique alpha-numeric value assigned to each feature (primary key). USGS NCGMP, 2020 Values are unique within this database. Example of value: "GLO01" HierarchyKey [HKey] (DescriptionOfMapUnits, GeoMaterialDict) String that records hierarchical structure. Has form nn-nn-nn, nnn-nnn, or similar. Numeric, left-padded with zeros, dash-delimited. Each HierarchyKey fragment of each row is the same length to allow text-based sorting of table entries. USGS NCGMP, 2020 Examples of values: "01" or "17-02-01" IdentityConfidence [IdeConf] (ContactsAndFaults, GeologicLines, MapUnitPolys, OrientationPoints) Confidence that feature is correctly identified. USGS NCGMP, 2020 questionable Identity of a feature cannot be determined using relevant observations and scientific judgment; therefore, one cannot be reasonably confident in the credibility of this interpretation. For example, IdentityConfidence = questionable is appropriate when a geologist reasons "I can see some kind of planar feature that separates map units in this outcrop, but I cannot be certain if it is a contact or a fault." USGS NCGMP, 2020 certain Identity of a feature can be determined using relevant observations and scientific judgment; therefore, one can be reasonably confident in the credibility of this interpretation. USGS NCGMP, 2020 unspecified Used for the boundary of a map where no confidence is specified. USGS NCGMP, 2020 Inclination [Inc] (OrientationPoints) Dip or plunge, measured in degrees down from horizontal. Values of -9 indicate value unknown. USGS NCGMP, 2020 -9 90 degrees (angular measure) IndentedName [IndNam] (GeoMaterialDict) Name with addition of leading spaces to help show rank within a hierarchical list.
