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 The database contains 7759 age determinations from 4828 rock samples, summarizing 622 published articles, theses or unpublished reports.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.
A 2020 publication (BCGS GeoFile 2020-10) add 532 ages from 66 papers and reports from the BC Geological Survey, Geoscience BC, and external publications. The ages were determined using ten mineral-isotopic systems and six dating methods, predominantly U-Pb zircon. This release contains two CSV files and one Microsoft Access file. The CSV files, one for new data (new_age_2020.csv) the other for BCAge data (bc_age_2020.csv), were generated with simplicity, exchangeability, and GIS-readiness in mind. They contain sample location coordinates, age, and numerous other primary attributes. The Microsoft Access database file, which is available through the GF2020-10 publication link, includes entities, and relationships, and metadata.
