Reprocessing of Yukon magnetic data for NTS 116I

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.

Enhanced interpretation of stream sediment geochemical data for NTS 115H

New geochemical data from re-analysis of archived stream sediment samples have been assessed using weighted sums modeling and catchment basin analysis as described in the methodology report that accompanies this map (YGS Open File 2015-10). Both commodity and pathfinder element abundances are evaluated to highlight areas that show geochemical responses consistent with a variety of base and precious-metal mineral deposit types. The results of modeling, completed using two approaches, are presented as a series of catchment maps and associated data files. This release is part of a regional assessment of stream sediment geochemistry that covers a large part of Yukon.

First vertical derivative of the magnetic field, Eagle Plains Aeromagnetic Survey, NTS 116 J (south half), Yukon

This map of the first vertical derivative of the 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 total magnetic field.

First vertical derivative of the magnetic field, Aeromagnetic Survey of the Nisling River Area, NTS 115 H/14 and part of 115 H/15, Yukon

This high sensitivity aeromagnetic survey was carried out by Goldak Airborne Surveys (Goldak) on behalf of the Geological Survey of Canada (GSC) between January 25th and March 26th, 2011. Aircraft equipment operated included three cesium vapour magnetometers, a GPS real-time and post-corrected differential positioning system, a flight path recovery camera, VHS titling and recording system, as well as radar and barometric altimeters. All data were recorded digitally in GEDAS binary file format. Reference ground equipment included two GEM Systems GSM-19W Overhauser magnetometers and a Novatel 12 channel GPS base station which was set up at the base of operations for differential post-flight corrections.

Eighty two flights (including test and calibration sorties) were required to complete the survey block. A total of 37,999 line kilometres of high resolution magnetic data were collected, processed and plotted. The traverse lines were flown at a spacing of 400 m with control lines flown at a separation of 2400 m. Nominal terrain clearance was specified at 100 m above ground.

Yukon Digital Geology (version 2)

Yukon Digital Geology presents a variety of geoscience data sets in digital format on the geology of Yukon. Included are syntheses of bedrock geology and glacial limits, compilations of geochronology, paleontology, mineral occurrences, oil and gas wells, and a compendium of aeromagnetic images. A subset of a public domain topographic data set (Digital Chart of the World, by ESRI, Inc.) is included for georeference purposes.

For ease of use, data sets are divided geographically into 45 map tiles corresponding to the National Topographic System (NTS) 1:250,000 quadrangles. Data sets spanning the entire Yukon are also included.

Each theme for all of the 45 map tiles is presented in two projections; an Albers Equal Area projection and UTM coordinate system. Vector data files are also presented in several different file formats (ArcInfo coverages; Interchange (*.e00), dBase (*.dbf), shapefiles (*.shp), and image data files are presented in band interleaved by line (*.bil), and tagged image file format (*.tif).
