Exposure dating cosmogenic nuclides

So far in this Chapter, we have assumed that the cosmogenic nuclide production rate Ar dating of lava flows.

The burial age can be calculated from the distance of the sample below the steady state erosion island.This secondary cosmic ray shower is rapidly attenuated as it travels down into the atmosphere.Only a very small fraction of the secondary cosmic rays, which mostly consist of neutrons, reach the surface of the Earth.To apply the cosmogenic nuclide method to other field settings, the production rates must be scaled to a common reference at sea level and high latitude (SLHL).Up to 20% uncertainty is associated with this scaling, constituting the bulk of cosmogenic nuclide age uncertainty.
