This update of the Yukon bedrock geology map builds upon the previous compilation by Gordey and Makepeace (1999, 2001). The data set includes the bedrock geology, faults and contacts, geochronology and map index; published by Yukon Geological Survey (January 2022). New digital data are being released incrementally and will be updated regularly as new parts of the compilation are ready. Any errors noted by the user of this data should be reported promptly to the Yukon Geological Survey.

Contains digital data files that were assembled or created from the 2002 Glenlyon component of the Targeted Geoscience Initiative (TGI) project. All data are provided in formats easily explored using widely available free softwares. Features include GIS spatial data of bedrock and surficial geology, generalized background topography and georeferenced geophysical and satellite raster images. Interactive map projects to allow viewing and querying of the spatial data using a variety of common GIS software (ArcExplorer 2.0, ArcView 3.x, ArcMap 8.x, and MapInfo) Databases of field observations (bedrock and surficial geology) Publications relevant to the study area, including open file maps, and a collection of reports from the Yukon Exploration and Geology (YEG) series A photo gallery to illustrate representative rock units and surficial geology features Free softwares (Adobe Acrobat Reader 5 and ESRI ArcExplorer 2) for viewing publications and interactive maps.

Geological map (1:1,000,000 scale) of the Yukon Territory, including the following inset maps: terrane map; physiographic regions map; glacial limits map; aeromagnetic image map; and NTS index map.

The Yukon bedrock geology map is in constant evolution as new mapping, geochronology and other geoscience studies improve the stratigraphy, and bring more detailed relationships into focus. The Digital Bedrock Geology GIS dataset used to produce this map is regularly updated and can be downloaded from the Yukon Geological Survey’s website:http://data.geology.gov.yk.ca/Compilation/3. Users are advised to consult the website regularly to ensure they are working with the latest version of the geodatabase or shape files. This Open File map is based on the 2022 version of the bedrock geology dataset; it is accompanied by a detailed Legend (Sheet 2) that summarizes current understanding of rock assemblages and stratigraphic units. The Yukon bedrock geology map can also be viewed and queried online using the Yukon Geological Survey interactive map service: https://yukon.ca/en/yukon-geology#bedrock-geology.

The Yukon Digital Bedrock Geology dataset was first released in 1999. It was rebuilt and expanded in 2016 and has since received regular updates. This paper summarizes the enhancements made to the bedrock geology dataset since 2016, the other ancillary geoscience datasets available, and the various ways to access and use the dataset.

Contains all the digital data files that were assembled or created during the Finlayson Lake TGI project. It includes two MS Access databases of field observations (bedrock and surficial), scanned and digitized maps, a series of georeferenced images (geophysical and LandSat), and a collection of reports from the Yukon Exploration and Geology (YEG) series. The data are presented in formats that can be viewed using four software products. Adobe Acrobat Reader 5 and ESRI ArcExplorer 2 are provided. Microsoft Internet Explorer is required to view the interface screens (Netscape may not work properly). A runtime version of Microsoft Access is also included to view the field databases if the user does not already have Microsoft Access installed on their computer. These four software products, or equivalent licensed versions, must be installed to utilize the full interactive capability. The spatial data can also be manually opened or imported.

Geographic Information Systems (GIS) spatial database of bedrock geology, surficial geology, mineral deposits, paleontology and geochronology for the Yukon Territory. It also contains a portfolio of georeferenced regional aeromagnetic images. All spatial database files are provided in two projections. The UTM coordinate system (disc 2) is commonly used at detailed scales. Albers equal area projection (disc 1) is provided to allow viewing or querying of larger areas that cross UTM zone boundaries. The datafiles are provided in various formats including an ARC/INFO coverage library, ARC/INFO interchange format (*.e00) and shapefile format (*.shp).

A placer mining and exploration compilation of NTS map sheets 115I and 115J/K, southern Yukon Territory, Canada. This compilation includes the location, history and previous work, description of bedrock geology, surficial geology and mineralization, as well as lists of related references. Accompanying the text are two 1:250,000-scale maps (NTS 115I and 115J/K) which display the locations of the placer occurrences discussed in the report.

This is a re-release of data collected and published as the Yukon GEOPROCESS FILE between 1994-1996. The data set is a compilation of information and knowledge on geological processes and terrain hazards in the Yukon Territory. The original work was carried out in three phases from 1992 to 1995. Contractors performed the work under the supervision of the Environmental Geologist, Exploration and Geological Services Division, Yukon Region, Indian and Northern Affairs Canada. The following individuals and companies were involved in carrying out the project: Mougeot GeoAnalysis, Aurum Geological Consultants Inc., L. Walton and C. Hart.
