GeoFIELD is a data management system that is designed to facilitate practical data entry and the production of geologic maps while in the field. GeoFIELD writes data to a Microsoft Access 2000 database and allows digitizing and plotting of station locations and structural data in an AutoCAD Map 2000 drawing using a Visual Basic for Applications interface. GeoFIELD provides a user-friendly interface within a familiar Windows environment. Its extensive picklists are easily customizable and ensure consistency and quality control during data entry. The widespread availability and easy customization features of Microsoft Access make GeoFIELD a flexible application that can be adapted to varying needs. In addition, Microsoft Access provides the ability to easily build complex database queries and generate reports. GeoFIELD can also be used successfully with a handheld device as well as with common GIS applications such as ArcGIS 8.x.

This map of the residual total magnetic field was derived from data acquired during an aeromagnetic survey carried out by Goldak Airborne Surveys during the period May 16, 2009 to July 1, 2009. The data were recorded using a split-beam cesium vapour magnetometer mounted in the tail boom of a Piper Navajo aircraft. The nominal traverse and control line spacings were 400 m and 2400 m, respectively, and the aircraft flew at a nominal terrain clearance of 150 m.

This CD-ROM contains digital data files that were assembled or created from the 2002 Glenlyon component of the Targeted Geoscience Initiative (TGI) project. All data is provided in formats easily explored using widely available free softwares, which are distributed on this CD. Features of the CD include GIS spatial data of bedrock and surficial geology, generalized background topography and georeferenced geophysical and satellite raster images. Interactive map projects to allow viewing and querying of the spatial data using a variety of common GIS software (ArcExplorer 2.0, ArcView 3.x, ArcMap 8.x, and MapInfo) Databases of field observations (bedrock and surficial geology) Publications relevant to the study area, including open file maps, and a collection of reports from the Yukon Exploration and Geology (YEG) series A photo gallery to illustrate representative rock units and surficial geology features Free softwares (Adobe Acrobat Reader 5 and ESRI ArcExplorer 2) for viewing publications and interactive maps. Navigation to the features described above is through a user-friendly interface which launches upon loading of the CD. All features can also be accessed through Microsoft Explorer.

This map of the first vertical derivative of the total magnetic field was derived from data acquired during a helicopter-borne aeromagnetic survey carried out by Fugro Airborne Surveys during the period between February 4 to March 15, 2010. The data were recorded using split-beam cesium vapour magnetometers (sensitivity = 0.005 nT) rigidly mounted on each of the two Astar 350B aircraft (C-FGSC and C-GAVO). The nominal traverse and control line spacings were, respectively, 400 m and 2 400 m, and the aircraft flew at a nominal terrain clearance of 100 m. Traverse lines were oriented N30?E with orthogonal control lines. The flight path was recovered following post-flight differential corrections to the raw Global Positioning System (GPS) 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.

This aeromagnetic survey was carried out by Goldak Airborne Surveys from February 17, 2014 to March 21, 2014. The data were collected using split-beam cesium vapour magnetometers mounted in each of the tail booms of 2 Piper Navajo aircraft. Nominal traverse and control line spacings were 400 and 1400 m, and the nominal terrain clearance was 125 m.

A 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 400m and 2400m respectively, and the aircraft flew at a nominal terrain clearance of 125m. Traverse lines were oriented at 0 degrees with orthogonal control lines.
