**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.

This dataset represents the interpreted Magnetic Domains of the Province of Saskatchewan. Regions of like magnetic intensity and/or structural texture have been interpreted from new aeromagnetic data collected for the Athabasca Basin and surrounding environs. Interpretations were made using a variety of presentations of the primary data including total magnetic intensity (TMI), 1st vertical derivative of TMI, horizontal derivative of TMI, automatic gain control of TMI and tilt derivative. Where possible, the interpreted domains extend the aeromagnetic response from older rocks that flank the basin beneath rocks of the Athabasca Group. The data was created as a file geodatabase feature class and output for public distribution.
