Survey Description

In 2004, about 60 till samples were collected from frost boils (mudboils) over an area of approximately 10 000 km2 in the Wager Bay region, Nunavut.  Some gossanous material was also sampled.  The data are published in Geological Survey of Canada Open File 5014.  The kimberlite indicator mineral data are published in GSC Open File 5087.

Open File 5014 includes data for samples collected in 1986 and previously published in Open File 2351.

Data Description:

CD-ROM including digital data

Quantities Analysed:

<0.063 mm fraction of till by ICP-AES following aqua regia digestion (3HCl-1HNO3) for a suite of trace and major elements; by INAA for Au + suite of trace, major and rare earth elements.

Geochem Maps Available:

Proportional symbol maps showing dispersal of elements in the <0.063 mm fraction of till

Other Analyses:

Textural analysis, gold grains.

Sampling Procedure

Samples (3 kg + 10 kg) were collected at depths ranging from 20 to 50 cm.  Oxidation and organic layers were avoided.
