Cosmogenic exposure age dating

So in the case of an eroding surface, the cosmogenic nuclide content can be used not to measure an exposure age, but an erosion rate ( Let us now move on to a cosmogenic radionuclide in a surface that undergoes no erosion.

When such an element is hit by a cosmic ray, it undergoes ‘spallation’, which basically means that it explodes into smaller particles.

During the 20 years or so that cosmogenic nuclide geochronology has been around, it has truly revolutionised various aspects of geomorphology, such as the study of volcanoes, river incision, landslides, glaciers, sediments, and faults.

Table 8.1 lists the most commonly used cosmogenic nuclides.

Obviously, the most common application of burial dating is the dating of cave sediments.

By measuring the age of different cave levels in the walls of a river canyon, it is possible to determine the rate of canyon incision.
