Soil, till and stream water sampling, NTS 13E/6, 7, 13K/5, central Labrador, 1999.
(requires an Internet connection)
A total of 418 soil and/or till samples were collected in 1999 in the Wilson Lake and Seal Lake areas, central Labrador. Till sampling was conducted along lines oriented at approximately right angles to glacial flow. Lines were located 1 km apart and samples collected every 200 m along the lines. Wherever possible, C-horizon till was collected. In some cases, only B- or B-C horizon material was available. Hand dug pits averaged 60 to 70 cm in depth. In all, 226 samples of C-horizon, 77 samples of BC-horizon and 115 samples of B-horizon were collected.
A total of 114 stream water samples were collected in 1999 from 111 sites in the Wilson Lake and Seal Lake areas, central Labrador. Two clean 250 ml Nalgene bottles were filled at each site, generally from the center of the stream. One bottle was reserved for pH and conductivity analyses, the other for trace metal analyses. The waters for trace element samples were filtered using a 0.45 μm millipore filtration apparatus.
The data are published in Newfoundland and Labrador Department of Mines and Energy Open File LAB/1327.
Paper report with data on diskette.
<0.180 mm fraction of soil and till samples by INAA for a large suite of elements; by ICP-AES after HF-HClO4-HCl digestion for a large suite of elements; by AAS after HF-HClO4-HCl digestion for Cr and Mo; by AAS after HNO3 digestion for Ag; by fluoride-ion selective electrode after fusion with Na2CO3-KNO3 flux for F.
Stream waters filtered (0.45 μm) and acidified (HNO3) then analysed by ICP-ES for Ca, Fe, K, Mg, Mn, Na, Si, SO4; by ICP ultra sonic nebulizer for Al, Ba, Be, Co, Cr, Cu, Li, Mo, Ni, P, Sr, Ti, Y, Zn.

The geographic extent of the survey is defined by the following polygons:
Covers parts of NTS 13E/6 (Metchin River) and NTS 13E/7 (Wilson Lake) in the Wilson Lake area, central Labrador. It is located approximately 5 km north of Wilson Lake.
Covers part of NTS 13K/5 (Wuchusk Lake) in the Seal Lake area, central Labrador. It is located between Wuchusk Lake to the north and Seal Lake to the south.
Covers parts of NTS 13K/4 (Dorothy Lake) and 13K/5 (Wuchusk Lake) in the Seal Lake area, central Labrador. It is located south of Whiskey Lake and north of Thomas River. Seal Lake is located approximately 6 km to the north.
