| Abstract | This new surficial geology map product represents the conversion of Map 1973A (Dyke, 2001) and its legend, using the Geological Survey of Canada's Surficial Data Model (SDM version 2.3.14, Deblonde et
al., 2018). All geoscience knowledge and information from Map 1973A that conformed to the SDM were maintained during the conversion process. The purpose of converting legacy map data to a common science language and 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 air photo
interpretation and fieldwork. 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. |
