Ecologically Based Landscape Classification Data

This dataset represents electromagnetic conductors for the Province of Saskatchewan at 1:1 million scale. This dataset represents electromagnetic conductors compiled from assessment files. The data was created as a file geodatabase feature class and made available for public distribution. Locations may be 200 to 300 meters off due to unknowns such as datums and projections of information submitted to the assessment files and due to poor location maps. **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.

Mining Leases

This map presents an interpretation of the bedrock geology of the Livingstone Creek area that has been revised from a previous Open File map (YGS OF2005-9). The revised interpretation was guided by the acquisition of a detailed VTEM Plus geophysical survey over the area in spring 2016 (YGS OF2016-34 and 35; 200 m line spacing). The detailed magnetic data were particularly useful for increasing the accuracy of contact locations, and identifying additional structures. The electromagnetic survey identifies a number of conductors across the area, some of which remain unexplained (see Colpron et al. in YEG 2016 for discussion). Bedrock exposure is locally hindered by Quaternary glacial and fluvial sediments, particularly in the South Big Salmon valley. Projection of the geology is guided by the geophysics in areas of extensive cover.

This dataset contains miscellaneous point features including: * mine head frames * cadastral iron bar (a type of survey monument) * historical monuments * horizontal control monuments * mile posts * smoke stacks We are no longer updating this data. It is best suited for historical research and analysis.

Quantitative gamma-ray spectrometric and aeromagnetic helicopter-borne geophysical survey was completed by Fugro Airborne Surveys. The survey was flown from September 10 to October 14, 2008. The nominal traverse and control line spacings were 400 m and 2400 m respectively, and the aircraft flew at a nominal terrain clearance of 125 m. Traverse lines were oriented at 0 degrees with orthogonal control lines.

Reprocessing of magnetic data for Yukon was performed between November 2016 and March 2017. Aeromagnetic data were compiled, data of different resolutions were merged, and a series of images individually levelled for each map sheet were produced. For each 250k-scale map, the following magnetic derivative maps were produced: 1. Residual Total Magnetic Field; 2. Reduced-to-Pole Magnetic Field (RTP); 3. First Vertical Derivative of the Reduced-to-Pole Magnetic Field (RTP_VD); and 4. Tilt Derivative of the Reduced-to-Pole Magnetic Field (RTP_TDR). These maps are provided as pdfs, geotiffs and Geosoft grid files. Colour ramps/legends are provided for each map.

This map of the total magnetic field was derived from data acquired during an aeromagnetic survey carried out by EON Geosciences Inc. in the period between April 10, 2009 and September 16, 2009. The data were recorded using split-beam cesium vapour magnetometers (sensitivity =0.005 nT) mounted in each of the tail booms of a Piper Navajo and a Cessna 206 aircraft. The nominal traverse and control line spacings were, respectively, 800 m and 2 400 m, and the aircraft flew at a nominal terrain clearance of 250 m. Traverse lines were oriented N90°E with orthogonal control lines. The flight path was recovered following post-flight differential corrections to the raw Global Positioning System data and inspection of ground images recorded by a vertically-mounted video camera. The survey was flown on a pre-determined flight surface to minimize differences in magnetic values at the intersections of control and traverse lines. These differences were computer-analysed to obtain a mutually levelled set of flight-line magnetic data. The levelled values were then interpolated to a 200 m grid. The International Geomagnetic Reference Field (IGRF) was not removed from the magnetic field.

These structure, isopach and zero edge files are part of a series of stratigraphic framework maps for the Saskatchewan Phanerozoic Fluids and Petroleum Systems (SPFPS) project. The series of stratigraphic framework maps for the Saskatchewan Phanerozoic Fluids and Petroleum Systems (SPFPS) project have been produced using 2 km equi-spaced modified grids generated from Golden Software’s Surfer 9 kriging algorithm. The dataset used to produce each of the maps in this series was created using data from several projects completed by the Ministry (Christopher, 2003; Saskatchewan Industry and Resources et al., 2004; Kreis et al., 2004; Marsh and Heinemann, 2006; Saskatchewan Ministry of Energy and Resources et al., 2007; Heinemann and Marsh, 2009); these data were validated and edited as required to facilitate correlations between the various regional projects. In addition, to minimize edge effects during contouring, the senior author also generated stratigraphic data from wells in adjacent jurisdictions.
