Survey Description

A total of 209 1-kg till samples were collected in the Lac de Gras area, Northwest Territories in 1992 (n=26) and 1993 (n=183). The data were released in GSC Open File 2868. A complete report, including gold grain analysis, was published in GSC Open File 3205. Approximately 80 ten-kg till samples were also collected for kimberlite indicator mineral analysis. The KIM data are published in GSC Open File 3079.

Data Description:

Paper report; data lists on diskette (Excel 3.0) (GSC OF 2868). Paper report; text and data files on diskette (WP, ASCII, Excel 3.0) for GSC OF 3205.

Quantities Analysed:

<0.002 mm and <0.063 mm fractions of till by ICP-AES after aqua regia (3HCl:1HNO₃) for 28 elements. <0.063 mm fraction by INAA for 35 elements (GSC OF 2868). <0.002 mm fraction by ICP-AES after nitric-aqua regia digestion for 28 elements; <0.063 mm fraction by INAA for 35 elements.(GSC OF 3205).

Geochem Maps Available:

Proportional dot maps showing dispersal of elements in the <0.002 mm and <0.063 mm fractions (GSC OF 3205).

Other Analyses:

Heavy mineral concentrate for gold grain counts (GSC OF 3205) and kimberlite indicator minerals (GSC OF 3079).
