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 map depicts the metamorphic facies for the Province of Saskatchewan, Canada.This map depicts the metamorphic facies for the province of Saskatchewan. The Precambrian Shield of Northern Saskatchewan has a complex metamorphic history with as many as six distinct thermotectonic events affecting various regions. Several of these result from major periods of crustal thickening attributed to orogenies, whereas others represent separate pulses of unknown origin. As might be expected, it is the most recent of these that are the most extensively preserves and that can be documented most reliably.

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).

Background:More than 80% of the heat produced in the Earth's crust comes from granitoid rocks. When granitoid rocks form they naturally concentrate radioactive elements such as U, Th, and K, and the radiogenic decay of these elements is an exothermic reaction. The radioactive decay of these elements within a granitoid body may generate local heat anomalies and elevated geothermal gradient at relatively shallow crustal levels. In combination with other local rock properties (e.g, porosity, permeability, thermal conductivity), radiogenic heat has the potential to generate a geothermal resource. The decay of radioactive elements converts mass into radiation energy, which in turn gets converted to heat. While all naturally radioactive isotopes generate some heat, significant heat generation only occurs from the decay of 238 U ,235 U ,232 Th and 40 K. Therefore, potential heat production is governed by the concentrations of U ,Th and K in the rock. In igneous rocks, radiogenic heat production is dependent on the bulk chemistry of the rock and decreases from acidic (e.g. granite) through basic to ultra basic rock types. Therefore, granites with anomalously high concentrations of U ,Th and K are targets for calculating potential radiogenic heat production. Potential radiogenic heat production (A)from plutonic rocks can be calculated using this equation:A (\\u03BCW/m 3 )=10 -5 \\u1D29 (9.52c u +2.56c K +3.48c Th )where "c" is the concentration of radioactive elements "U" and "Th" in ppm, and "K" in %; and "\\u1D29" is the rock density. Heat production constants of the natural radio-elements U, Th, K are 9.525x10 -5 , 2.561x10 -5 and 3.477x10 -9 W/kg, respectively.Data and Methods:Geochemical data from \~1760 samples of plutonic rocks from Yukon are used to calculate potential heat production. The calculated values for radiogenic heat production (A) are plotted over the mapped distribution of Paleozoic and younger plutonic rocks and major crustal faults are also shown for reference.

This layer contains polygon features that represent geological units in New Brunswick. The associated Bedrock Geology Relate Table contains details about each map unit, including: a brief legend description, Group name, Formation name, and rock age. This layer is the result of nearly 50 years of bedrock mapping and it continues to change as new interpretations are made and more data is collected through field work and analysis.

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) .

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