Carbon dating quartz

Assuming that the boulder remains in a stable position, and does not roll or move after deposition, this boulder will give an excellent As well as using cosmogenic nuclide dating to work out the past extent of ice sheets and the rate at which they shrank back, we can use it to work out ice-sheet thicknesses and rates of thinning[5, 6].

Spallation reactions occur in minerals in the rocks upon bombardment by cosmic rays.However, this can be difficult, as thermal boundaries within the ice sheet may mean that it is more erosive lower down than higher up, and that cold, non-erosive ice on the tops of mountains may leave in tact older landscapes.Cosmogenic nuclide dating can also be used in this context to understand past ice-sheet thicknesses and changes in subglacial thermal regime.Glacial geologists are often interested in dating the maximum extents of glaciers or rates of recession, and so will look for boulders deposited on moraines.Once exposed to the atmosphere, the boulder will begin to accumulate cosmogenic nuclides.
