Resumo
The Hercynian basement of the Iberian Peninsula has undergone different stages of supergenic weathering which has given rise to a superposition of several «weathering mantles». Remnants ofan old weathering mantle, Mesozoic in age, and related to a planation surface older than the Alpine tectonic phases, have been found. Nowadays the fragments of this old surface appear unleveled
and/or fossilized by younger sediments. likewise, related to the «Raña» sediments ofUpper Neogene-lower Pleistocene age, appears a weathering mantle, probably active today, which is rich in
kaolinite and with strong hydromorphic features.
