Surficial Geology
Surficial geology focuses on the description of the types and distributions of unconsolidated sediments across the landscape. Surficial-geological data is essential for the successful interpretation of ice flow and glacial history in Manitoba. This information is collected and maintained primarily in maps and databases. It is useful for mineral exploration, sand and gravel production, hazard assessment, and infrastructure and landuse planning.

Digital capture of potential aggregate depositsThis data capture is part of an ongoing project to compile existing Manitoba Geological Survey aggregate publications and digitally capture the spatial data component in a GIS format. This is intended as an initial release of the data capture, which will be followed by additional data published as an Open File. |
