BCAge database contains all reported non-proprietary isotopic age determinations for bedrock units from British Columbia, Alberta, Washington and Alaska. The database contains 7759 age determinations from 4828 rock samples, summarizing 622 published articles, theses or unpublished reports. The data is fully relational, and may be queried by the user on the basis absolute age (in Ma), location (NTS mapsheet, terrane polygon, or decimal lat-long, as specified by the user) or source (e.g. author, journal title, etc.). This data has also been integrated into MapPlace and is available as an MS Access database in BCGS Open File 2004-03. This 2004 compilation is also available in a flat tabular format for ease of use.
