Attribute tables and geospatial features (points, lines, and polygons) conform to the Geologic Map Schema (USGS NCGMP, 2020) and represent the geologic map as published in USGS Miscellaneous Investigations Series I-1319. The 276,000-acre map area represents the geology at a publication scale of 1:48,000.

U.S. Geological Survey National Cooperative Geologic Mapping Program, 2020, GeMS (Geologic Map Schema) - A standard format for the digital publication of geologic maps: U.S. Geological Survey Techniques and Methods, book 11, chap. 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 the central Pioneer Mountains, Blaine and Custer counties, central Idaho. 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, geologic and geophysical mapping efforts, petrologic studies, and mineral resource assessments. PioneerMtns_I-1319.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 (PioneerMtns_I-1319.gdb) contains the following elements: --GeologicMap: feature dataset (subdirectory) containing the following feature classes (GIS layers): ----CartographicLines: line layer (feature class) representing 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 marker beds. ----MapUnitPolys: polygon layer representing the distribution of geologic map units. ----OrientationPoints: point layer representing orientations of bedding, foliation, joints, fault dips, cleavage, lineation and minor folds. ----OverlayPolys: polygon layer representing areas of breccia and contact metamorphism. --DataSources: table that lists sources and (or) references used to derive spatial features (points, lines, and 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 FEDMAP component of the National Cooperative Geologic Mapping Program. Microsoft Windows 11 Enterprise, Version 23H2 (Build 22631.5189); Esri ArcGIS Pro 3.5.5 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. Point, line, and polygon features were digitized from the I-1319 map and quality assured for completeness. Textual information from the original printed map 'Description of Map Units' section was transcribed into the DescriptionOfMapUnits table. Horizontal accuracy of point, line, and polygon features is dependent on the accuracy of the 1:48,000 scale source map. Map publication techniques employed in 1983 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. James H.

The data were captured by staff at East View Geospatial by heads-up digitizing of the georeferenced version (compressed GeoTiff) of the Dover (1983) printed geologic map obtained from the National Geologic Map Database. Dover, 1983 2023 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 (Dover, 1983), GeMS (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 represented 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 validation tools.
