Objectif(s): To investigate the architecture of Pleistocene deltas on the Mackenzie River tributaries, search evidence of high-magnitude discharge events, and collect samples for absolute dating.
Description du projet: The objective of this project is to investigate the architecture of Pleistocene deltas on the Mackenzie River tributaries, search evidence of high-magnitude discharge events, and collect samples for absolute dating. The research team will investigate the stratigraphic description of sedimentary sections in the river banks cutting through the Pleistocene deltas. Collection of samples are for radiocarbon dating (used on preserved organic material) and optically stimulated dating (used on sand). The research team will collect small samples at different levels (about 1 litre of sediment) that the team will process in the lab to identify plant fossils for potential radiocarbon dating. There will be no in situ testing or significant impact from this work. The samples will be collected with hand shovels and trowels in order to ensure contaminant free sampling of the materials. These radiocarbon dates will allow the research ... Plus de résultats
