Canadian Geochronology Knowledgebase
The compilation represents publicly available reports of geochronological
information for Canada. This includes federal, provincial and territorial
government publications and reports, university theses, books and journals,
as well as unpublished data points released by individual geochronologists.
Current coverage is limited to those areas that have been the target of
recent past compilation efforts, with other areas and updates being included
as they become ready. Every effort is made to report the ages without
reinterpreting the original authors intent. However, care has also been
taken to highlight the salient features of the data by which the end-user
can make initial judgment on the data robustness. Users are cautioned
that because of space limitations and the necessary summarization of often
complex datasets, that the original publication should be consulted to
verify age interpretations and their rationale.
Please note the following information:
- Samples without reasonable geographical location information are not included in the compilation.
- Samples without errors (marked by "0" uncertainty), or with large errors, should be treated as rough estimates.
- Detrital zircon analyses have not been screened to take into account the degree of discordance, a strong factor in the level of confidence that can be ascribed to analyses.
