For ArcGIS users, to symbolize the regional and detailed polygons and linework, please download this zip file containing the associated layer files.

For MapInfo users, to colour the geology polygons, please go to the MapInfo Tools website, go to the MapInfo Extensions section and click on 'A' to find all the tools starting with 'A'.  The  addcolor-243 MapBasic program is near the top of the list.  Link to that section and download the file.  In MapInfo, run the ADDCOLOR.MBX program through the MapInfo Tools section.  The RGB colour values are in various fields in the shape file tabular dataset (e.g., D_Red, D_Green and D_Blue fields colour the 'detailed' geology polygons). You may need to convert the shape file to a MapInfo file first.


Further maps are available on the Map Indexes website . This site, among other links, provides links to the Index of Bedrock Geology Maps for Newfoundland and the Index of Bedrock Geology Maps for Labrador, similar to the Index of Bedrock Geology Maps layer on the Geoscience Atlas.
