dc.descriptionABSTRACT: The micas are rock forming mineral of the phyllosillicates group. The weathering of these minerals is fundamental in the understanding of potassium, silicon and magnesium liberation processes to the soil. the existent studies shown that the main factors that control the micas weathering are the pH of the solutions, the temperature, the size of the particles and the superficial area. The micas weathering is incongruous, in other words, always new minerals are formed as dissolution products, as vermiculite, kaolinite and goethite. These products can precipitate in the surface of the mica, especially the iron oxides of iron, and they impede the contact with its surface, reducing the dissolution kinetics. The structure of the micas is also a decisive factor in the dissolution kinetics. The dissolution kinetics presents the following decreasing order: phlogopite, biotite, and muscovite.pt_BR
