Genesis of Vermiculite and Mixed-Layered Vermiculite in the Evolution of the Soils of France
Published online by Cambridge University Press: 01 January 2024
Abstract
Analysis of the argillaceous fraction of some podzolic soils and podzols of France has shown a double evolution of illite and chlorite through mixed layering into vermiculite. $ilite \to \left( {illite - vermiculite) \to vermiculite} \right) \\ chlorite \to \left( {chlorite - vermiculite} \right) \to vermiculite \\$
Vermiculite is more concentrated in the upper zones of the profiles where it constitutes 50 to 90 percent of the argillaceous fraction.
