We have an array of equipment and facilities for cosmogenic nuclide sample preparation at the University of Wyoming. The first step in the process is to isolate quartz from everything else in our ...

Temporal variations in coarse river deposits are often attributed to climate change. Cosmogenic nuclide concentrations of river cobbles suggest that climate plays a subordinate role to earthquake ...

After isolating one particular nuclide from that mineral, they send a beam of cesium ions at the sample. That adds an extra electron to atoms within the sample, forming negative elemental or molecular ...

Using cosmogenic nuclide burial dating methods and optically stimulated luminescence dating, geoscientists establish ages for river deposits from the Yukon River basin that span key time periods ...

To test that idea, they directly dated the cave breccias in Members 2 and 4 using cosmogenic nuclide dating, which Dr Granger helped develop. Earth’s surface is constantly peppered by cosmic rays.

To gauge the ages of the hominid skeletal remains, Granger and his team used a technique known as "cosmogenic nuclide dating," or burial dating, which involves examining the rocks that encased the ...

Clark and her colleagues used a dating method known as “cosmogenic nuclide surface exposure dating,” which works by “dating a boulder that was deposited by the ice sheet when it first ...
