Soils formed from serpentinized rocks or serpentinites constitute a special group of soils on the earth surface. These rocks present ultramafic characteristics, with more than 70 % mafic minerals (iron and magnesium oxides). The mineralogy of serpentinites is poor in silica and aluminum and very rich in Mg. Only few studies have looked into the morphology, mineralogy, genesis and classification of soils developed on this type of parent material. In the humid-tropical climate of southwestern Minas Gerais state, three representative soil […]
