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 Hailey 1 x 2 degree quadrangle, 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 as well as to other geologic and geophysical mapping efforts, petrologic studies, and mineral resource assessments. Hailey_1x2degrees.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 (Hailey_1x2degrees.gdb) contains the following elements: --GeologicMap: feature dataset (subdirectory) containing the following feature classes (GIS layers): ----ContactsAndFaults: line layer representing locations of contacts and faults. ----DataSourcePolys: polygon layer representing the spatial extent of geologic map data sources used within the map boundary as captured from the printed map inset 'Additional Sources of Geologic Data'. ----GeologicLines: line layer representing the locations of dikes. ----OverlayPolys: polygon layer that delineates areas of mylonitized rock. ----MapUnitPolys: polygon layer representing the distribution of geologic map units. --DataSources: table that lists sources and (or) references used to derive spatial features (lines, polygons), attribute information, and geologic map data sources captured from the printed map inset 'Additional Sources of Geologic Data'. --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. --RepurposedSymbols: table that lists standard FGDC geologic map symbols that have been repurposed. In this case, the custom symbology on the printed map used for sheared unconformity lines is replaced with FGDC symbol 02.12.01.

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), 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 3.4.3 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 digitized and extracted 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 and line features were digitized from the GM-10 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 line and polygon features is dependent on the accuracy of the 1:250,000 scale source map. Map publication techniques employed in 1991 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. Ron G. Worl Thor H. Kiilsgaard Earl H. Bennett Paul K. Link Reed S. Lewis Victoria E. Mitchell Kathleen M. Johnson Lori D.

The printed map was obtained from the Idaho Geological Survey (https://www.idahogeology.org/Product/GM-10) 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 (compressed GeoTiff) of the Worl and others (1991) printed geologic map and saved as an Esri file geodatabase in GeMS format. Worl and others, 1991 2022 The Esri file geodatabase was further attributed, edited, and compared to the original map plate (Worl and others, 1991) to check for digitizing and attribution errors. Corrections were made as needed. The topographic basemap used on the original printed geologic map (USGS, 1962) was used to digitize water boundaries and close some map unit polygons. Water polygons were created from the newly digitized lines and attributed with proper names as shown on the basemap. Areas of mylonitized rock on the printed map are only represented by symbols and hard to delineate. Boundaries for these areas were approximated as best as possible by drawing polygons around the symbols in the OverlayPolys feature class. Map unit labels for swarms of dikes were hard to distinguish in many areas and were left unassigned in the GeologicLines feature class. The printed map does attempt to distinguish between types of dikes; however, the ambiguity of the labeling and symbology lead to uncertainty. Please see the printed map as needed. Polygons representing sources of geologic data used to create the printed geologic map were digitized into the DataSourcePolys feature class from the map inset 'Additional Sources of Geologic Data' and references were entered into the DataSources table. 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 (Worl and others, 1991), GeMS (USGS NCGMP, 2020), and from the Glossary of Geology (Neuendorf and others, 2011). The original printed map is black and white, therefore map unit colors were chosen using previously published adjacent geologic maps and the Techniques and Methods 11-B1 (USGS WRD, 2005). Map unit colors 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 GeMS validation tools.

Examples of values: "contact" or "dike" Type (ContactsAndFaults, GeologicLines, OverlayPolys) Classifier that specifies what kind of geologic feature is represented by a database element: that a certain line within feature class ContactsAndFaults is a contact, fault, or water boundary. USGS NCGMP, 2020 contact A plane or irregular surface between two types or ages of rock. Neuendorf and others, 2011 contact, gradational A gradational contact representing facies change. A lateral or vertical variation in the lithologic or paleontologic characteristics of contemporaneous sedimentary deposits. It is caused by, or reflects, a change in the depositional environment. Worl and others, 1991 contact, mylonitic A contact for mylonitic fine-grained, foliated rock, commonly with poor fissility and possessing a distinct lineation. Usually found in narrow, planar zones of localized ductile deformation, although kilometer-scale zones exist. Mylonites are often inferred to indicate extensive simple shear, but they may also record pure shear or volume loss or both. Introduced by Lapworth in 1885 and originally thought to have formed by the crushing and milling of minerals, it is now understood to form by one or more of the crystal plastic deformation mechanisms. Neuendorf and others, 2011 dike A tabular igneous intrusion that cuts across the bedding or foliation of the country rock. Neuendorf and others, 2011 fault A discrete surface or zone of discrete surfaces separating two rock masses across which one mass has slid past the other. Neuendorf and others, 2011 fault, normal A fault in which the hanging wall has moved downward relative to the footwall. The angle of the fault is usually 45-90 degrees, and in most cases close to 60 degrees. Ball and bar on downthrown block. Neuendorf and others, 2011 fault, normal, low-angle A fault in which the hanging wall has moved downward relative to the footwall. The angle of the fault is usually 45 degrees or less. Half-circles on upper plate. Neuendorf and others, 2011 fault, strike-slip, right-lateral A fault on which the movement is parallel to the fault's strike and which the side opposite the observer has been displaced to the right. Neuendorf and others, 2011 fault, thrust A fault with a dip of 45 degrees or less over much of its extent, on which the hanging wall has moved upward relative to the footwall. Sawteeth on upper (tectonically higher) plate. Neuendorf and others, 2011 fault, thrust, younger-over-older Fault is probably a Mesozoic thrust later reactivated as a low-angle normal fault. Sawteeth on upper (tectonically higher) plate. Worl and others, 1991 map boundary A line representing the boundary of the mapping area. Worl and others, 1991 mylonitized rock Deformation of a rock by extreme microbrecciation, due to mechanical forces applied in a definite direction, without noteworthy chemical reconstitution of granulated minerals. Characteristically the mylonites thus produced have a flinty, banded, or streaked appearance, and undestroyed augen and lenses of the parent rock in a granulated matrix Neuendorf and others, 2011 sheared unconformity Shear is a deformation resulting from stresses that cause or tend to cause contiguous parts of a body to slide relatively to each other in a direction parallel to their plane of contact. Unconformity is a substantial break or gap in the geologic record where a rock unit is overlain by another that is not next in stratigraphic succession, such as an interruption in the continuity of a depositional sequence of sedimentary rocks or a break between eroded igneous rocks and younger sedimentary strata. It results from a change that caused deposition to cease for a considerable span of time, and it normally implies uplift and erosion with loss of the previously formed record. No movement direction inferred, arrows on younger side. Neuendorf and others, 2011 water The outline of a body of water (lake) and/or stream. Worl and others, 1991 URL (DataSources) Uniform Resource Locator (URL) or Digital Object Identifier (DOI), identifies a document on the World Wide Web.
