Surficial Geology of Southern Ontario - Polygon Representation
Coordinate system: 4269 - "NAD83"Abstract:
The Surficial Geology of Southern Ontario 2010 - Polygon Representation feature captures surficial geology unit polygons, which classify the earth's surface by the surface or nearsurface geological material.
The map has recently been revised and updated and replaces the map previously released on MRD 128. This new version now includes surficial geology information for the Bruce Peninsula and as well as NTS sheet 31D\9 covering the Burleigh Falls area. It illustrates surficial deposit types, material types, geological features (e.g. drumlins, eskers) and general bedrock types and outcrops.
The Surficial Geology of Southern Ontario 2010 data set is a GIS based geological map that shows the distribution and characteristics of surficial units across Southern Ontario. It illustrates surficial deposit types, material types, geological features (e.g. drumlins, eskers) and general bedrock types and outcrops. The surficial geology of southern Ontario consists largely of varying types and thicknesses of deposits emplaced primarily during the Quaternary period. These surficial deposits overly a bedrock terrain consisting mainly of Phanerozoic sedimentary rocks that overlie older Precambrian rocks of the Canadian Shield.
The data used in generating the map was derived from Quaternary maps, primarily at a scale of 1:50 000, completed by the OGS and Geological Survey of Canada (GSC) for most of southern Ontario over the past 40 years.
The Surficial Geology of Southern Ontario 2010 - Polygon Representation feature is part of the Surficial Geology of Southern Ontario 2010 series. The other features are available on the GeoPortal and can be located by searching the following titles:
