Survey Description


In 1996, 112 one kg till samples were collected from the northern Contwoyto Lake map area, Nunavut.  An additional 25 ten kg samples were collected at some of the sites for regional kimberlite indicator mineral and gold grain analysis.  The till and gold grain data are published in GSC Open File 3654.  The KIM data are published in GSC Open File 3768.

Data Description:

Paper report; text and data files (WP 6.0, Excel 3.0) on diskette.

Quantities Analysed:

<0.002 mm fraction by ICP-ES after aqua regia for 28 elements and <0.063 fraction mm by INAA for 35 elements.

Geochem Maps Available:

Proportional symbol maps showing dispersal of selected elements.

Other Analyses:

Heavy mineral concentrate for kimberlite indicator minerals (GSC OF 3768); grain size.
