Till sampling, NTS 22A, B, G, H, Gaspé, Québec.
(requires an Internet connection)
Till samples were collected from approximately 160 sites in the Gaspé area, Québec. No sampling year was given. Samples were taken every 0.5 m depth to bedrock. The density of sampling was greater if a facies changed occurred within the 0.5 m interval. Sample weight varied between 0.5 – 1.5 kg. A description of the study can be found in P. Bédard’s Université de Montréal Ph.D. Thesis.
