  abstract = {{T}he mineralogy of the {L}atosols of the {B}razilian {C}entral {P}lateau remains under discussion in the absence of a clear relationship with their age according to their geomorphic location. {T}he aim of this study was thus to clarify the origin of the kaolinite and gibbsite content variation by studying a regional toposequence and using data from the literature. {C}hemical composition and soil color were used to discuss mineralogy. {T}he mineralogy of the clay fraction was also investigated using {X}-ray diagrams. {O}ur results showed that the large variation of kaolinite and gibbsite content can be explained by taking into account both their local and regional location, the variation of the hematite and goethite content remaining limited. {T}he model that is proposed to explain such variation combines a regional component, which is mainly associated to the age of the geomorphic surface and a local component which is mainly associated to the hydraulic conditions along the toposequence. {T}o cite this article: {A}. {R}eatto et al., {C} {R}. {G}eoscience 340 (2008).},
