Till sampling survey, NTS 21P/5, northern New Brunswick, 1996.
(requires an Internet connection)
In 1996, 202 till samples were collected in the western two-thirds of the Nepisiguit Falls map area, northern New Brunswick. These samples filled in gaps from a regional Geological Survey of Canada survey in the area (GSC OF 2236). Basal till was sampled at the plotted sample site (2 km grid centres) where possible, and at the nearest possible point if the site was in a bog or stream or underlain by extensive bedrock. Several pits were sampled in glaciomarine and glaciolacustrine sand and silt in the central part of the area to test the geochemical response of these sediments. The data are published in New Brunswick Department of Natural Resources and Energy Open File 99-10.
Paper report with data diskette.
<0.063 mm fraction analyzed for Au and 34 other elements by INAA; by a combination of ICP-ES (after digestion by nitric, perchloric and hydrofluoric acids followed by a lithium metaborate fusion) and ICP-MS for a total of 51 major and trace elements.
Geochem Maps Available:
At each site, a sample comprising approximately 5 kg of basal till and approximately 75 pebbles (>1 cm) from till was collected from hand dug pits 0.5 to 1 m deep.
