Survey Description


In 1993, 117 1-kg till samples were collected in the Winter Lake area, Northwest Territories. The data were released in GSC Open File 2908.  A complete report, including gold grain analysis, was published in GSC Open File 3206.  Approximately 49 ten kg till samples were also collected for kimberlite indicator mineral analysis.  The KIM data are published in GSC Open File 3081.

Data Description:

Paper report; text and data on diskette (WP, ASCII, Excel 3.0) for GSC OF 2908.  Paper report; geochemical data and illustrations on diskette (Excel 3.0, ASCII, and WP) for GSC OF 3206.

Quantities Analysed:

<0.002 mm and <0.063 mm fractions of till by ICP-AES after aqua regia (3HCl:1HNO 3) for 28 elements; <0.063 mm fraction by INAA for 35 elements for GSC OF 2908.  <0.002 mm fraction by ICP-AES (Chemex) after nitric-aqua regia digestion for 29 elements; <0.063 mm by INAA for 35 elements for GSC OF 3206.

Geochem Maps Available:

Proportional dot maps showing dispersal of elements in the <0.002 mm and <0.063 mm fractions (GSC OF 3206).

Other Analyses:

Heavy mineral concentrate for kimberlite indicator mineral analysis (47 samples; GSC OF 3081).  Heavy mineral concentrate for gold grain counts (GSC OF 3206).
