Autogenic and allogenic denudation in carbonate karst by the multiple basin method: An example from Svartisen, North Norway
Abstract In carbonate karst basins, adequate denudation rates are difficult to estimate when there are allogenic inputs. It is shown that the common practice of correcting for allogenic input by Corbel's modified formula leads to erroneous results unless the karst ratio is very high. When choos...
