Till sampling survey, NTS 21G/2 (St. George), southwest New Brunswick, 2003.
(requires an Internet connection)
During the 2003 field season, glacigenic sediments were collected in the St. George map area, southwest New Brunswick. Site locations were based on a flexible 2 km grid (1 sample per 4 km2). A field duplicate was taken for each block of 20 samples. Using stainless steel equipment, a total of 110 till samples (excluding field duplicates) were collected from natural exposures, road-cuts and hand-dug excavations. Sample material was obtained from the C-horizon at a mean depth of 0.75 m and consisted of approximately 5 lbs of material and 60 to 100 clasts. Basal till was the preferred sample medium, but ablation till was collected in areas where it could not found. The data are published in New Brunswick Department of Natural Resources and Energy Open File 2004-5.
