Survey Description
Follow-up geochemical surveys were carried out in the Yellowknife Greenstone Belt area, Northwest Territories in 2000 and 2001 as detailed below:
| NTS | Year | Sample Type | No. of Samples | GSC Publications |
|
85J/8, 9, 16 85O/1 85P/4 (68 sites) |
2000 | till (10 kg) | 67 |
Current Research 2000-C1 OF 4019 (includes data from samples collected in a regional orientation survey in 1999) |
| black spruce bark | 10 | |||
| leaf litter | 4 | |||
| humus | 4 | |||
|
85J/8, 9, 16 (33 sites) |
2001 | till (10 kg) | 32 | Current Research 2002-C7 |
| till (1 kg) | 14 | |||
| leaf litter* | 5 | |||
| humus* | 6 | |||
| soil* | 20 |
* these samples were collected from two soil profiles
The data form part of a compilation of regional till geochemistry from surveys carried out in the Slave Province between 1992 and 2001 and published in GSC OF 5015. Fifteen samples from this compilation collected in 2001 in NTS 76C, D by D. Kerr are included in this survey but no analytical data have been published.
Data Description:
Paper report, no data lists.
Quantities Analysed:
<0.002 mm fraction by ICP-AES after nitric-aqua regia digestion for 39 elements; <0.063 mm fraction by INAA for 34 elements.
Geochem Maps Available:
Soil profiles for selected elements at 2 sites.
Other Analyses:
Ashed vegetation samples analyzed by ICP-MS and INAA.
Sampling Procedure
The area was surveyed using road access and helicopter-assisted traversing. Soil samples weer collected from hand-dug pits or excavated sections at depths of 10 to 70 cm.

The geographic extent of the survey is defined by the following polygons:
-
Covers a very small part of NTS 85J/10 (Narcisse Lake; 1 sample) in the Yellowknife area, Northwest Territories. It is located 8 km north of the shore of Great Slave Lake and 33 km northwest of Yellowknife, just south of Highway 3 (Yellowknife Highway).
-
Covers parts of NTS 85J/8 (Yellowknife Bay), 85J/9 (Prosperous Lake), 85J/16 (Quyta Lake), 85O/1 (Barker Lake) and 85P/4 (Thistlewaite Lake), in the Yellowknife area, Northwest Territories. It is bounded to the south by Great Slave Lake. The city of Yellowknife is found in the southern part of the study area.
-
Covers part of NTS 76C (Aylmer Lake) and a small part of 76D (Lac de Gras; 2 samples) in the Lac de Gras area, Northwest Territories. It is bounded to the southwest by Lac de Gras and is located approximately 15 km south of the Nunavut-Northwest Territories border.
