Surficial Geology Compilation Map Series (SGCMS)

Introduction

The Surficial Geology Compilation Map Series (SGCMS) addresses an increasing demand for consistent surficial geology information for applications such as groundwater protection, industrial mineral management, protected lands, basic research, mineral exploration, engineering, and environmental assessment. In addition, aggregate resources depicted on the maps are applicable to the heavy construction and building industries.

The SGCMS provides seamless province-wide coverage at scales of 1:250 000 and 1:500 000 including the NTS and regional map sheets for southern Manitoba (south of 53°N) released in 2004. A final compilation at 1:1 000 000 was released in 2007 and supersedes the original Surficial Geological Map of Manitoba (Nielsen et al., 1981).

The regional 1:500 000 scale maps north of 53°N and the 1:250 000 scale maps south of 53°N include

  1. surficial geology polygons draped on hill shaded topographic relief derived from the Shuttle Radar Topography Mission Digital Elevation Model (SRTM DEM) (United States Geological Survey, 2002)
     
  2. a brief description of the Quaternary landscape of northern or southern Manitoba,
     
  3. major landforms of Manitoba with specific reference to the glacial ice flow direction, and
     
  4. a paleogeographic reconstruction of late glacial events in Manitoba.

The two-sided 1:1 000 000 scale map includes all information above as well as:

  1. a full colour graphic description of map units which includes photographs and diagrams to define each unit in lay terms (ROCK – R, TILL – T, GLACIOFLUVIAL – G, GLACIOLACUSTRINE – L, GLACIOMARINE – M, ALLUVIUM – A, EOLIAN – E, COLLUVIUM – C, MODERN SHORELINE SEDIMENTS – Lm, ORGANIC – O)
     
  2. an index map showing the location of each of these photographs
     
  3. diagrams depicting the effect of isostatic rebound on Manitoba’s Tyrrell Sea and Great Lakes regions
     
  4. a look into the 3rd dimension by way of a 3D block diagram cut through the two largest cities in the province.

Methodology

Paper copies of the most current and detailed surficial geology maps of various scales published by the Geological Survey of Canada and/or the Manitoba Geological Survey (MGS) were digitized for this compilation. Polygons for several areas were derived from digital geological maps. Digital polygons derived from soils mapping were used to fill gaps in the geological mapping. Edge-matching of adjoining map sheets was based on data from the SRTM DEM as interpreted by the MGS. Other polygon gaps and inconsistencies were modified in a similar manner. The surficial geology (coloured) is draped over a shaded topographic relief map (grey tones) derived from the SRTM DEM.

All source map units were converted into a standardized legend and housed in a database that can be queried to retrieve the original interpretation which can be used to colour maps based on a variety of material characteristics. The 1:250 000 scale maps reference the source of the polygons.

Print and web formats

Paper copies of the 1:500 000 scale maps and the 1:250 000 scale maps for NTS areas south of 53°N are available from MGS Publication Sales (see contact information below). The 1:250 000 scale maps north of 53°N are available in digital format only. All SGCMS maps are available on-line for viewing or free download by clicking on the images above, or as interactive maps through the GIS Map Gallery.

Suggested references

To assist users in referencing SGCMS maps, all maps provide a suggested reference for each 1:250 000 and 1:500 000 map sheet as a stand-alone product, regardless of the format (PDF, paper, ESRI® shapefiles) or access point (DVD or web). The following examples, using the Norway House NTS 63H map sheet, are provided to assist users in referencing SGCMS maps based on format and access point (highlighted text changes with NTS or regional map sheet).
