Description :
This paper provides a quantitative analysis of the rates and processes of bedrock erosion for a mountainous catchment floored by resistant, variably foliated and ubiquitously jointed granitic bedrock. The AA. use Be 10 concentrations in bedrock and alluvial sediment to provide a measure of the rates at which these processes operated in recent (late Quaternary) geologic time. The results are placed into tectonic and climatic contexts in order to explain how an anomalously rugged, high relief mountain belt has developed in the middle of a continent generally known for its tectonic quiescence and climatic aridity.
