Latosols are deeply weathered soils characteristic of the most Tropics. These soils represent 1/3 of the Brazilian National Territory and occupy about 40% of the Brazilian Central Plateau. The objective of this study was to discuss the distribution of the Latosols on the geomorphic surfaces from Brazilian Central Plateau based on geochemical process. Ten Latosols (L) developed in different parent materials were selected along an approximately 350km long regional toposequence across the South American Surface (L1
to L4) and Velhas Surface (L5 to L10) from Brazilian Central Plateau. The main conclusion is that there is a close relation between the occurrence of gibbsite(Gb), kaolinite (K) and hydroxy-Al interlayered vermiculite (HIV) in the soil-solution phase versus their presence in the equilibrium soil-solid phase for these Latosols independently of the geomorphic surface. The presence of HIV is not consistent with the weathering process in the tropical areas where the tendency is the progressive loss of Si and the enrichment of Al consequently Gb. |
