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 after HCl-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 Maps 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 fraction of non-magnetic heavy minerals;  heavy mineral counts (0.063 mm-0.250 mm fraction).

In 1992 a further 278 till samples were collected.  The data from both field seasons are published in GSC Open File 3038.
