3he cosmogenic nuclide age dating
Because ^3He is produced in all mineral phases, it can potentially be applied in almost any lithology.
The goals of this thesis is to expand the range of target lithologies suitable for cosmogenic ^3He dating by calibrating production rates of cosmogenic ^3He in accessory mineral phases such as apatite, zircon, and garnet.
This button will apply a pre-existing experiment to the data in the sample browser.
To indicate the progress of the experiment a progress bar pops up which tracks the progress of the experiment: Then these samples can be exported to a csv file (using the Export Samples dialog button) or analyzed using the ACE graphics output (see below for an example), or with CALVIN using the Analyze Samples dialog button.
Why does ACE use experiments to date samples and not just compute an age?
From the pulldown menu we choose ‘3He Demonstration Expt': When you click on ‘OK’, the experiment will operate on the samples.
Note that for very old samples, or very small timesteps, this may take a long time.Studies in many of these fields could greatly benefit from analysis of far more samples than can be easily dated using ^(10)Be, ^(26)Al, and ^(36)Cl.
