| Sumario: | The soils are part of the landscape and they can infer about their evolution. On areas with more stables reliefs is possible to find deep and pedogenetically evolved soils, because the nature and local landscape allowed such evolution. Soil keeps records about its evolution and through the attributes is possible to infer about its current evolution stage. On this purpose, it was performed a pedological study to investigate two Latossolos (Oxisols)from Marechal CândidoRondon, Paraná, Brazil. The choice of this soil classes is justified by being the most representative on the region and being great studies shortage about the mineralogical description and evolutional around these soils on the west of Paraná, Brazil. So it was studied one complete alteration soil profile and another one with until two meters deep (control section) in order to obtain a first approximation of the evolution level from pedological covering and the acting pedogenetical processes. It was performed in this work a chemical, physical and mineralogical analysis, which one the results confirmed the kaolinite nature those Latosols (Oxisol). The mineralogical assembly is, predominantly, composed of 1:1 (kaolinite), but also has minerals 2:1 (vermiculite with hydroxyl-interlayered). The results indicate that was predominat process monossialitization with partial hydrolysis along pedogenesis, in accordance the local landscape and environment formation under subtropical climate (very weathered). |
