Drift prospecting; geochemistry of eskers and till in permanently frozen terrain: District of Keewatin, Northwest Territories

Geochemical results are reported for a program that compared samples collected from eskers and adjacent till in permanently frozen terrain. Contrasting effects of disturbance on the well- and poorly sorted sediments within the active (seasonally thawed) zone are discussed. Trace element geochemistry of several textural and mineralogical fractions of each sample is reported, compared and explained. A previously known area of copper-nickel mineralization is clearly outlined by anomalies in various fractions of both till and esker samples. Other anomalies, possibly related to unknown sources, are also described. It is concluded that some potentially interesting ore minerals (sulphides and carbonates) are removed from the active zone of eskers and till by intense chemical weathering. Clays and secondary oxides that can scavenge cations released by this weathering are preferentially removed by surface runoff from mud boils on till, but are retained within the porous structure of the thawed zone of eskers. Thus, silt and clay (-250 mesh) is recommended for analysis in esker samples but must be used with caution when analyzing t ill. Heavy mineral separates from near-surface esker and till samples from permanently frozen terrain are not recommended for routine analysis. Micas, magnetite, clay, and rock fragments can reflect economically interesting mineralization, suggesting that some mineral phases in rocks adjacent to mineralized zones may be enriched in the cations characteristic of those zones. This implies that a target for drift prospecting may be larger than the mineralized zone its e lf.

Fort-a-la-Corne; Line star-1; 2D seismic reflection

The Orion South (140/141) kimberlite is a kimberlite located within the Fort à la Corne field of central Saskatchewan. An extensive drilling program was conducted to delineate the subsurface extent of the kimberlite complex. In addition, a set of 2-D seismic reflection profiles was acquired as to constrain interborehole geological correlations.

Timmins 2D; North Timmins Regional; 2D seismic reflection

Nine lines of two-dimensional (2D) reflection seismic surveying using Vibroseis vehicles as sources were acquired in the Timmins–Kirkland Lake area of Northern Ontario in mid 2004. The survey was designed to expand the seismic testing westward to Timmins to develop reflection images under the surveyed lines across major structures,stratigraphy and lithology of special interest to economic mineralization.

Dates of formation and loss of snow cover

The map shows isolines on four different dates: 1) the day of the year when there are less than or equal to 2.5 centimetres of snow that occurs and remain absent for 7 or more days; 2) the standard deviation of the mean date of snow cover loss; 3) the day of year when greater than or equal to 2.5 centimetres of snow occur and remain for more than 7 days; and 4) the standard deviation of the mean date of snow cover formation. The beginning and end of the winter season in Canada is usually identified with the formation and disappearance of snow cover in autumn and spring respectively. The duration of snow cover varies considerably from year to year in the southern fringes of the country and adjacent to the east and west coasts. However, even in northern continental areas early and late snowfalls which leave an ephemeral snow cover are common. The beginning and end of the Canadian snow season is the earliest and latest dates when 2.5 centimetres or more snow was measured. However, this definition is difficult to apply to the Prairie Provinces, where snow cover is relatively shallow and is subjected to sudden melting and new accumulations at the season extremities. For the Prairie Provinces, the definition can be modified by specifying that the initial cover of 2.5 centimetres (or more) should remain for at least 7 days, and that the date of loss would occur at the beginning of a 7-day period with less than 2.5 centimetres on the ground in spring. This definition was adopted for the present map. Snow cover data have been regularly measured at principal meteorological stations since 1941. The present map is based on the 1955-1972 period. Unfortunately, records prior to 1955 are not available in the form required for the selected computer analysis. To generate data for the map, a total file of over 500 meteorological station records was accessed and the means, standard deviations, and other arithmetic data were calculated. The mean dates of formation and loss and their standard deviations were plotted on a 1 : 5 000 000 scale orographic base map to guide isopleth interpolation.

Canada 1-km, 10-day, SPOT/VEGETATION composites for growing season-2000-01-11

As part of the climate change research, data from the SPOT/VEGETATION instrument are systematically corrected for period 1998-2004 and provided in this archive. The VGT archive contains observations acquired by the VEGETATION sensors 1 and 2 onboard SPOT 4 and 5 satellites. Initial data type 10-day S10 composites provided by the Centre National d'Etudes Spatiales (CNES) and pre-processed at the Flemish Institute for Technological Research (VITO) in Belgium in full resolution (1km) were re-projected into standard Lambert conformal conic map projection and further corrected for bi-directional Reflectance Distribution Function (BRDF) effect and cloud contamination. Growing seasons 1998-2004 are presented with twenty 10-day composites from April 11, to October 31. Each composite contains four at-surface apparent reflectance bands: blue (0.43-0.47 mm), red (0.61-0.68 mm), near infrared (0.78-0.89 mm), and shortwave infrared (1.58-1.75mm) and two data layers containing normalized difference vegetation index (NDVI) and Cloud mask. The 10-day composite data were reprocessed following Canada Centre for Remote Sensing (CCRS) post-seasonal correction. This improved product is used in land cover and climate change studies to generate various high-level products such as Fraction of Photosynthetically Active Radiation (FPAR) and Leaf Area Index (LAI).
