Australian Inselbergs

Australia is, for the most part, a tectonically stable continent. Analysis of cosmogenic 10-Be and 26-Al show that granitic inselbergs sampled in both the Eyre Penninsula and north toward Darwin have very high nuclide concentrations and correspondingly low erosion rates on the order of decimeters to a few meters per million years.
