摘要：
We calculate the chemical depletion fraction of the D-anitic bedrock by analysing the rock-soil enrichment of zirconium. In Vendee (France), chemical weathering rates account for 26% of the denudation rates. Such a chemical depletion fraction characterizes temperate regimes. It is three times lower than that of humid tropical regimes.
