Survey Description
In 1994, 190 1-kg till samples were collected in the Napaktulik Lake area, Nunavut. Forty-five additional 10 kg till samples were collected for kimberlite indicator mineral and gold grain analyses. The till geochemistry and gold grain results are published in GSC Open File 3316 and the KIM data in GSC OF 3355.
Data Description:
Paper report and 1 diskette (WP5.0, ASCII and Excel3.0 formats).
Quantities Analysed:
<0.002 mm fraction by ICP-AES after aqua regia (3HCl:1HNO3) for 28 elements. <0.063 mm fraction by INAA for 35 elements.
Geochem Maps Available:
Proportional symbol maps showing dispersal of elements in the <0.002 mm and <0.063 mm fractions of till.
Other Analyses:
Pebble lithologies; heavy mineral concentrate (45 samples) for gold grain counts and non-magnetic heavy minerals for kimberlite indicator minerals (see GSC OF 3355).
