This website is the public interface to the "Canadian Database of Geochemical Surveys". The database has two long-term goals. Firstly, it aims to catalogue all of the regional geochemical surveys that have been carried out across Canada, beginning in the 1950s. Secondly, it aims to make the raw data from those surveys available in a standardised format. Over 1,500 surveys have been catalogued. Approximately 500 are considered to be of long-term strategic value for mineral exploration and environmental baseline studies. Work is progressing on standardising the data for these 500 surveys. To date over 250 datasets have been converted.
