The Yukon Territory is underlain by a great variety of rock types ranging in age from Early Proterozoic to Recent and representing diverse environments including epicratonic basins, subsiding shelves, foreland basins, island arcs and deep ocean basins. Episodes of compressional and extensional deformation, transcurrent faulting, metamorphism and plutonism further complicate the map pattern. This complex geological record has been described in terms of the interactions of several terranes (large parts of the earth's crust which preserve a common geological record) with each other and with the margin of ancestral North America.

A Yukon-wide compilation of map footprints and associated citation data for 191 published bedrock geology maps that were incorporated into the Yukon bedrock geology compilation. The maps were originally produced by the GSC, YGS, Yukon Government and various universities at various scales ranging from 1:10,000 to 1:500,000. Attribute data for each map footprint includes: year, scale, author, publisher, map number, NTS sheet and title.

The lithogeochemical data provides the chemical composition of rock samples. This data helps characterize the rocks and can be used to understand their mode of formation.

The Yukon is underlain by a great variety of rock types ranging in age from Early Proterozoic to Recent. The various rock types are characterized by different magnetic intensity and this map shows those variations at the regional scale, with highly magnetic rocks represented by warm colours and non-magnetic rocks shown in cool colours. The Residual Total Field magnetic map shows a measure of the total magnetic intensity in the Earth's crust. This magnetic compilation was extracted from the compilation of Oneschuk et al. (2019). The data was gridded at 50 m. Magnetic data for Yukon can be obtained from: [http://gdrdap.agg.nrcan.gc.ca/](http://gdrdap.agg.nrcan.gc.ca/) Distributed from [GeoYukon](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/maps) .

Yukon Bedrock Geology MapThis update of the Yukon bedrock geology map builds upon the previous compilation by Gordey and Makepeace (1999, 2001). It includes new, detailed bedrock geology maps and regional compilations that have been published by the Yukon Geological Survey and the Geological Survey of Canada between 1999 and 2015, as well as some recent thesis works. A few of these maps were partially integrated into the digital dataset by Gordey and Makepeace (2003), but only as overlay to the 1999 compilation. A number of errors and omissions from the 1999 compilation of Gordey and Makepeace were also noted and corrected during compilation of this version of the map. The Yukon bedrock geology GIS dataset is regularly updated and can be downloaded from the Yukon Geological Survey's website: www.geology.gov.yk.ca. Users are advised to consult the website regularly to ensure they are working with the latest version of the geodatabase or shape files. This update of the GIS dataset includes an expanded attribute structure (compared to the 1999 dataset) that facilitates searching of the geodatabase. The Yukon Geological Survey aims to provide users with the best available geoscience data for Yukon. Any revisions or additional geological information known to the user would be welcomed by the Yukon Geological Survey.

Geochronology is a discipline of geoscience which measures the age of earth materials and provides the temporal framework in which other geoscience data can be interpreted in the context of Earth history. This knowledge helps to answer questions such as when did a volcano last erupt, what is the rate of crustal uplift in a specific area, are rocks at one gold prospect the same age as those at another.
