'''Ferrallitisation''' is the process in which [[rock (geology)|rock]] is changed into a [[soil]] consisting of [[clay]] ([[kaolinite]]) and [[sesquioxide]]s, in the form of hydrated oxides of iron and [[aluminium]]. In humid [[tropical]] areas, with consistently high temperatures and rainfall for all or most of the year, [[chemical weathering]] rapidly breaks down the rock. This at first produces clays which later also break down to form [[silica]]. The silica is removed by [[Leaching (pedology)|leaching]] and the sesquioxides of iron and aluminium remain, giving the characteristic red colour of many [[tropical|tropical soil]]s. Ferrallitisation is the reverse of [[podsolisation]], where silica remains and the iron and aluminum are removed. In tropical [[rain forest]]s with rain throughout the year, ferrallitic soils develop. In [[savanna]] areas, with altering dry and wet climates, [[Iron oxide|ferruginous]] soils occur.
