Description :
The production of regolith is a fundamental geomorphic process because most surface processes transport only unconsolidated material. The AA. use concentrations of the cosmogenic radionuclides (CRNs) 10Be and 26Al in regolith and bedrock to deduce the rate of production of regolith on an alpine hillslope in the Wind River Range, Wyoming. These calculations are based on a theoretical model which is developed here. This model shows that it is important to consider dissolution of regolith in regolith production and in basin-averaged erosion rate studies.
