Analyse structurale et cartographie en pédologie II - Une méthode d'analyse prenant en compte l'organisation tridimensionnelle des couvertures pédologiques

A method for the analysis of the three-dimensional structure of the soi1 mantle of elementary landscape units is exposed through trvo examples from French Guiana. The first one presents sandy-clay old precoastal bars, with ferralitic soils changing to podzolic soils. The second one present an elementary catchment area on schist and pegmatite, whose soi1 mantle shows a complex water dynamics. A general method, @tted to the Guianese area, is then exposed with, for guidance, time required for such studies.
