The bedrock geologic units designate units of the same types of rock which composed the solid rock exposed at ground surface (as outcrop) or which underlies unconsolidated surficial sediments. This dataset represents a general description of the stratigraphy and geology, including geologic unit thickness, morphology, age and rank. It features a list of the geologic unit names and types of rock (lithology) in the hydrogeological unit, from a controlled vocabulary. While the preferred format to deliver this data is by using a shapefile and its linked attributes, this dataset can be delivered also by providing link to external data which should have at least the same properties or also by joining a georeferenced image of the map.

This compilation sources data primarily from the Yukon Geological Survey’s (YGS) field projects and archival collections, and from the Geological Survey of Canada’s (GSC) Canadian rock physical property database (Enkin, 2014, 2018). The data distribution is far from uniform but covers a range of lithology classes and terranes. The compilation of data from archival samples is ongoing, and the dataset will continue to grow as new samples are collected for YGS projects and pass through the survey’s physical properties lab.The foundation of this dataset originates from samples collected for a mapping project in western Yukon led by Dirk Tempelman-Kluit from 1970 to 1972 (Tempelman-Kluit and Curie, 1978) and subsequently digitized by the Geological Survey of Canada and Mira Geoscience (2014). This dataset alone contributed 1642 records to the compilation. Map unit names from this original dataset were modernized for this compilation to reflect current understanding of Yukon geology.Systematic measurements of magnetic susceptibility and specific gravity have been incorporated into the workflow when archiving rock samples from YGS projects. Additional magnetic susceptibility measurements are also routinely collected in the field by YGS geologists. This will continue to expand the dataset. Rock samples are not collected specifically for the physical properties dataset but are well characterized and have sufficient metadata to be incorporated into the dataset. Samples are not uniform in size or weight.The Yukon Geological Survey’s HS Bostock Core Library houses >10 000 Yukon rock samples from previous and ongoing geological studies. Archived collections provide a great opportunity to further expand the dataset in specific regions or areas lacking representation.Distributed from [GeoYukon](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/maps).

Location of rock samples collected during Precambrian mapping projects more recent than 1985 in northern Saskatchewan and stored at the Subsurface Laboratory.Location of rock samples collected during Precambrian mapping projects more recent than 1985 in northern Saskatchewan and stored at the Subsurface Laboratory. This is an on-going compilation so not all map projects are present. The data was created as a file geodatabase feature class and output for public distribution. **Please Note – All published Saskatchewan Geological Survey datasets, including those available through the Saskatchewan Mining and Petroleum GeoAtlas, are sourced from the Enterprise GIS Data Warehouse.  They are therefore identical and share the same refresh schedule. 

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.Distributed from [GeoYukon](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/maps) .

Level below which soil or rock is saturated with water, in the well and at the time the level has been measured, expressed in m above the sea level. Groundwater levels measured are interpolated / extrapolated to obtain groundwater level on every cell of the hydrogeological unit raster. Surfer and ArcGis are the software usually used to create groundwater level raster. The dataset designates a raster with a groundwater level, for each cell of the hydrogeological unit.

A claim is a parcel of land located or granted for hard rock mining. A claim also includes any ditches or water rights used for mining the claim, and all other things belonging to or used in the working of the claim for mining purposes. A claim is a rectangular plot of ground that does not exceed 1,500' X 1,500'. All angles of a claim must be right angles, except in cases where a boundary line of a previously located claim is adopted as common to both locations.Distributed from [GeoYukon](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/maps) .

This GIS dataset is part of a digital compilation of the Precambrian geology of the Alberta portion of the Canadian Shield and Athabasca Basin. It is one of the datasets used to produce Alberta Geological Survey Map 537. The dataset displays locations on the Alberta shield where we took rock samples for 40 argon/39 argon dating. Attributes include crystallization and/or cooling age, mineral analyzed, sample identifier and rock type, literature reference, and analytical method. This is a digital version of Table 2 in Map 537.

This GIS dataset is part of a digital compilation of the Precambrian geology of the Alberta portion of the Canadian Shield and Athabasca Basin. It is one of the datasets used to produce Alberta Geological Survey Map 537. The dataset displays Alberta shield locations where we took rock samples for uranium-lead dating. Alberta Geological Survey compiled the data from published literature. Attributes include crystallization and/or cooling age, mineral analyzed, sample identifier and rock type, literature reference, and analytical method. This is a digital version of the data given in Table 1 of Map 537.

Groundwater samples have been collected in the hydrogeological unit, for various types of analysis. The dataset is not used to represent a particular phenomenon or observation but rather as a utility dataset to add context and reference to groundwater analysis. It represents a general description of the sample site and sample. Sampling methods vary according to the types of analysis.
