Characterization and genetic interpretation of clays in an acid brown soil (Dystrochrept) developed in a granitic saprolite


, : Characterization and genetic interpretation of clays in an acid brown soil (Dystrochrept) developed in a granitic saprolite. Clays and Clay Minerals 39(5): 519-530

Clay fractions separated from an acid brown soil (Dystrochrept) by high-gradient magnetic separation techniques were studied. Breakdown of large phyllosilicates preexisting in the saprolite involved physical fragmentation and mineralogical transformations strongly related to chemical weathering.
