BCAge 2004 is an MS-Access based database containing all reported non-proprietary isotopic age determinations for bedrock units from British Columbia. This release contains 7759 age determinations from 4828 rock samples, summarizing 622 published articles, theses or unpublished reports.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.). The product is not stand-alone; the end user must install Microsoft Access, version 2000 or XP (2002). This data has also been integrated into MapPlace.

Note - XP users must download the MS Access 2002 format of the database.
