Survey Description


In northeastern Alberta, 111 samples (mostly till) were collected in 1992, and 336 samples (mostly till) were collected in 1993 and 1994.  Heavy minerals were obtained from 10 till samples, but only one kimberlite indicator mineral was found.  Data published in GSC Open Files 2747 and 3348 (final report).

Data Description:

Paper reports; 1992 report has diskette (WP and Excel).  1993-1994 data on diskette in Excel format.

Quantities Analysed:

<0.002 mm and <0.063 mm fractions by ICP-AES after nitric-aqua regia digestion for 32 trace elements; 1993-1994 samples also have INAA of the sample matrix.

Geochem Maps Available:

None.

Other Analyses:

Grain size (<2 mm fraction); carbonate (<0.063 mm fraction by LECO); 10 of the larger 1993-1994 samples were processed for heavy mineral concentrates for kimberlite indicator minerals.
