| Abstract | This new surficial geology map product represents the conversion of Map 44-1989 and its legend, using the Geological Survey of Canada's Surficial Data Model (SDM version 2.3) (Open File 8236). All
geoscience knowledge and information from Map 44-1989 that conformed to the current SDM were maintained during the conversion process. Supplementary, limited legacy information was added to complement the converted geoscience data. This consists of
glacial striations from Wright (1955), as well as striations and field data from McMartin et al. (2017); these are identified in the accompanying geodatabase. The purpose of converting legacy map data to a common science language and a common legend
is to enable and facilitate the efficient digital compilation, interpretation, management, and dissemination of geological map information in a structured and consistent manner. This provides an effective knowledge management tool designed around a
geodatabase that can expand, following the type of information to appear on new surficial geology maps. |
| Summary | (Plain Language Summary, not published)
The map identifies surficial materials and associated landforms left by the retreat of the last glaciers. The surficial geology is based on aerial
photograph interpretation, field work and limited legacy fieldwork (striations). This work provides new geological knowledge and improves our understanding of the distribution, nature and glacial history of surficial materials. It contributes to
resource assessments and effective land use management. |
