Till Ontario 1991

Till sampling, NTS 52N,K, Red Lake-Woman Lake area, northwestern Ontario, 1991.  


Geological Survey of Canada, Terrain Sciences Division

Survey Description

138 till and 40 glaciofluvial sand samples were collected in the Red Lake-Woman Lake area, northwestern Ontario in 1991. The data are published in GSC Open File 2583.

Data Description: Paper report with one diskette (Excel 3.0).

Quantities Analysed: <0.063 mm fraction by ICP-AES afterHCl-HNO3 digestion for 28 elements and by fire assay-DCP after nitric-aqua regia digestion for Au, Pt, and Pd. Non-magnetic heavy minerals by INAA for gold and 34 elements.

Geochem Plots Available: Proportional symbol maps showing dispersal of elements, selected heavy minerals and gold grains.

Other Analyses: Pebble lithologies (5.6-16 mm fraction); heavy mineral concentrate for UV analysis, heavy mineral point counts. of the >0.25 mm of non-magnetic heavy minerals; heavy mineral counts (0.063 mm-0.250 mm fraction).

Project History

1991-1995 Northwestern Ontario till sampling survey carried out in 1991-1992.
  The project was designed to investigate the stratigraphy, sedimentology, composition and source of glacial sediments, especially till, in areas of potential bedrock mineralization. The Red Lake-Woman Lake-Confederation Lake area was chosen because producing gold mines and former base metal mines are located in the area and there is potential for further mining development. Glacial sediment covers large parts of the area and conceals promising targets. Drift prospecting in this area will aid exploration. The data are published in GSC Open Files 2583 and 3038. The till data have also been released as part of a geoscience compilation for the area in GSC Open File 3751.
