This dataset represents the Quaternary geology of the Richelieu project. The study area includes contiguous watersheds of Yamaska and Richelieu rivers, and the Missisquoi Bay. In the study area, there are three physiographic regions, associated with the Quaternary geology. In the St. Lawrence Lowland, there are silty, clayey sediments on the surface which can be covered by sandy sediments or silty sands. The Appalachian piedmont is mainly covered by till while the Appalachian Highland exhibits till but also numerous bedrock outcrops.
The purpose is to show a unified surficial geology of the study area. This dataset is used to realize other themes.
