Survey Description


In the summer of 1996, a total of 626 samples were collected in the Spider 3 survey area, in the region of the Upper Attawapiskat and Ekwan Rivers, northern Ontario.  Eighty-two samples were till, 510 were modern alluvium and 34 were glaciofluvial sediments.  The details of the survey are published in Ontario Geological Survey Open File Report 6097 and the data (geochemistry + KIM) in Miscellaneous Release-Data 109.

Data Description:

Paper report; digital data released as compressed ASCII and Excel files on diskette as MRD-109 (Miscellaneous Release-Data 109).

Quantities Analysed:

<0.063 mm fraction by INAA for 35 elements; by ICP-OES after a total (HNO3-HClO4-HF-HCl) digestion for 19 elements.

Geochem Maps Available:

Proportional symbol maps showing the dispersal of elements, based on data -80 mesh till and -60 mesh non magnetic tabled concentrates.

Other Analyses:

Heavy mineral processing (at Consorminex) for kimberlite indicator minerals (KIMs).
