    Chrome Users: The current version of Google Chrome (37) has an issue that doesn't allow pasting into the calculator. This is fixed in the new version of Chrome but hasn't been released yet (other than as a beta version called Chrome Canary). Once the new version of Chrome is released pasting will work with no issues.

    Until then, please try an alternate browser like Firefox or Internet Explorer.


    We are currently working towards our full release. As such, some of the features already in the published code are still being integrated into the web site. Features still under construction:

    • Scaling Schemes: LM, SF, ST, DU, LI
    • Nuclides: 21Ne
    • Plots: Al/Be banana plot
    • Geochron Database Upload
