Geology Maps

Online Reference

The Ontario Geological Survey provides an comprehensive package for Google Earth™ mapping service. The OGS Earth package contains, bedrock geology, surficial geology, elevation, gravity, magnetics, geophysics, and many other layers covering most of Ontario. Visit the Ministry of Northern Development Mines and Forestry site to download OGS Earth

The OGSR Library provides its own package for Google Earth™ mapping service called PxTools. Together with OGS Earth powerful overlays can be created to investigate Ontario's subsurface geology. Download PxTools by OGSR Library
