Ontario Geological Survey: bedrock, quaternary, and physiography

Description

This data resource is provided by the Ontario Geological Survey and shows general bedrock (iron formations, kimberlites, dikes, etc.) and quaternery geology (dunes, hummocky terrain, etc.) for all of Ontario. This represents data collected from 1950-2020. A more in depth level of data is provided for select 1:50,000 nts map sheet areas; 40p1, 40p2, and 40p7-10. This level of data contains information on specific primary material, secondary material, veneer, carbon content, age, provenance, and formation.

This physiography data covers Southern Ontario and is based on the Chapman and Putnam survey of the 1950's, with minor revisions in 1984. For more information please consult the book entitled: The Physiography of Southern Ontario by L J Chapman and D F Putnam, 3rd edition (Toronto, 1984) located in the Geospatial Centre, G3461.C5 svar P7x no. P-2715).
