Survey Description


Regional till sampling was carried out in central and northeastern Manitoba in 1996.  A 40 km spacing was considered adequate to define major features of the drift composition and regional trends in background for geochemical and indicator mineral variables.  At 78 sites, a 12 litre sample was collected from below the B-horizon at an existing exposure such as a road cut or riverbank, or from a shovel hole. Location, sampling depth, Munsell colour, reaction to HCl, texture, structure and moisture content were recorded at each site.  Of the 78 sites, 21 were road-accessible in the western part of the area and were sampled during a four-day period in late July.  At the 57 remaining sites to the east, till was sampled from shovel holes or river cuts accessed by float planes.  These sites were sampled over 6 days in late July and 7 days in mid-August.  The data are published in Geological Survey of Canada Open File 3449/Manitoba Energy and Mines Open File 97-3.

In 2008, forty-nine archived splits of the till samples collected in 1996 were reanalyzed for a study of Ni-Cu deposits in the Thompson nickel belt.  These new data are included in GSC Open File 6005.

These data are also part of a compilation, Geological Survey of Canada Open File 7064

Data Description:

Digital CD release.

Quantities Analysed:

<0.063 mm and <0.002 mm fraction analyzed for a suite of elements by ICP-AES following nitric-aqua regia partial dissolution; As by hydride generation – AAS and Hg by cold vapour-AAS.  <0.063 mm fraction by INAA.

Geochem Maps Available:

None.

Other Analyses:

<0.063 mm fraction for carbonate by Chittick; HMC for geochemical analysis by INAA.  Selected heavy mineral grains were analyzed mineralogically using the electron microprobe.  Pebble counts on 8-16 mm fraction.
