Radiocarbon Dating GSC data compared to the consensus values The Geological Survey of Canada Radiocarbon Dating Laboratory ceased operation at the end of 2005. This site will be maintained to provide reference information on the samples dated during the 45 years of operation of the GSC laboratory from 1960 to 2005.
