"The online exposure age calculator formerly known as the CRONUS-Earth online exposure age calculator:"

The same look, feel and performance you've come to rely on...with exciting new features and terrible documentation!

This is the version 3 data entry form. It should also accept version 2 input.

This code is expected to be stable for exposure-age calculations for He-3 in pyroxene and olivine and Be-10, C-14, Ne-21, and Al-26 in quartz. Although it is also functional for He-3 in quartz, this pair is still under development and may change without warning.

If you encounter an error or a failure, please email me the data that you entered and a description of the problem. Thanks.

Sample data entry:

Enter data block here.

These data are from a single landform. Attempt to detect outliers and calculate summary statistics.

Of course, if you enter data with multiple age populations, this option will likely give nonsensical results. In addition, it may fail completely with certain badly behaved data sets.
