Newfoundland and Labrador
Till sampling, NTS 2D/13, 14, 2E/3, eastern Newfoundland, 1997.
(requires an Internet connection)
In 1997, approximately 850 till samples were collected in the Grand Falls – Mount Peyton area, eastern Newfoundland. Sample spacing was roughly one sample per 2.25 km2 in areas of good access. In areas where helicopter support was required, sample spacing was roughly 1 sample per 4 km2. In total, diamicton was systematically sampled at 807 sites from below the B soil horizon wherever possible (samples were collected mostly from the BC or C-horizon). In addition, till profiles were collected from three backhoe pits, with sampling at 0.5 m vertical intervals. The data are published in Geological Survey of Newfoundland and Labrador Open File NFLD 2664.
<0.063 mm fraction analyzed for Ag by AAS after a HNO3 digestion; for 28 elements by ICP-AES after HCl-HCl04-HF digestion; for 25 elements by INAA.

The geographic extent of the survey is defined by the following polygons:
Covers NTS 2D/13 (Grand Falls), 2D/14 (Mount Peyton) and part of NTS 2E/3 (Botwood), the Grand Falls – Mount Peyton area, eastern Newfoundland. Highway 1 runs east-west through the study area. The cities of Bishop's Falls and Grand Falls-Windsor are located in the northern part of the study area.
