“…Asthis process intensifies, the cavities become connected, and the relative distribution develops to an open pattern. The dissolution process that produces the cavities, however, contributes to the illuviation process, which tends to increase and cover larger extensions of pore walls (Vidal-Torrado et al, 2006).…”

“…A significant expression of igneous mafic and ultramafic rocks is observed in the southeastern and southern region of Brazil, where a number of studies have investigated soil attributes associated with the nature of these parent materials (Pinto and Kämpf, 1996;Cooper and Vidal-Torrado, 2000;Vidal-Torrado et al, 2006;Campos et al, 2007). In a study on ultramafic rocks in the subtropical area of Rio Grande do Sul state, Pinto and Kämpf (1996) described shallow soils, with pH close to neutral, high CEC and base saturation, in addition to a high content of easily weathered primary minerals, which indicates slow weathering of the soils.…”

“…A composição mineralógica da fração argila é discutida em detalhe em Vidal-Torrado et al (2006). Apresenta mescla de minerais herdados (tremolita, talco e clorita), de transformação direta (interestratificados clorita-vermiculita e cloritaesmectita) e, por último, de minerais neoformados (caulinita, goethita e hematita) (Quadro 4), podendo neoformar também esmectitas e, talvez, talco nas fases iniciais de alteração.…”
