| Abstract | This new surficial geology map product represents the conversion of Map 38-1989 (Aylsworth, 1989) 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 38-1989 that conformed to the current SDM were maintained during the conversion process. Supplementary legacy information was added to complement the converted geoscience
data. This consists of striations from Wright (1955). 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 aerial
photograph interpretation and limited legacy 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. |
