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 densities and this map show those variations at the regional scale, with dense rocks represented by warm colours and lighter rocks shown in cool colours.This Bouguer gravity map was compiled by Nathan Hayward, Geological Survey of Canada. Data used in this Bouguer gravity compilation, gridded at 2 km, are from ground-based, regional (\~10 km station spacing) gravity surveys acquired by the Geological Survey of Canada and high-resolution (\~2 km station spacing) surveys acquired for the Yukon Geological Survey. All surveys are reduced to a Bouguer density of 2670 kg/m3 and statically levelled to the regional data.Corresponding regional gridded data can be downloaded, at no charge, from Natural Resources Canada's Geoscience Data Repository for Gravity Data at [http://gdrdap.agg.nrcan.gc.ca/](http://gdrdap.agg.nrcan.gc.ca/) . High-resolution gravity data can be downloaded from the Yukon Geological Survey at [https://data.geology.gov.yk.ca/](https://data.geology.gov.yk.ca/)Distributed from [GeoYukon](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/maps) .

The "Canadian Database of Geochemical Surveys" has two long-term goals. Firstly, it aims to catalogue all of the regional geochemical surveys that have been carried out across Canada, beginning in the 1950s. Secondly, it aims to make the raw data from those surveys available in a standardised format. Over 1,500 surveys have been catalogued. Of these, the raw data for over 300 have been converted to a standardised format. The catalogue can be searched at https:\\geochem.nrcan.gc.ca

Canadian Hydrographic Service (CHS) has made available all the publishable limits of modern day surveys whose data has been collected since 1989.

The Canadian Gravity Anomaly Data Base consists of approximately 660 000 gravity observations, including 165 000 on land, acquired between 1944 and the present. The data spacing ranges from less than 1 km to over 20 km, with an average spacing between 5 and 10 km. All measurements were reduced to the IGSN71 datum. Theoretical gravity values were calculated from the Geodetic Reference System 1967 (GRS67) gravity formula. Bouguer anomalies were calculated using a vertical gravity gradient of 0.3086 mGal·m-1 and a crustal density of 2 670 kg·m-3.
