Abstract


This work describes the study of two types of soil profiles , podzolic and brunizem . The profiles are localized at Avenida Brasil near the Cabritos viaduct in the city of Rio de Janeiro . Chemical analyses, pH values, sulfuric digestion (SiO2, Al2O3,Fe2O3, TiO2, K2O, Na2O), X-ray diffraction of the clay and silt fractions, mineralogical analyses of sand under the microscope , physical measurements of the Atterberg limits, grain size analyses and specific gravity of solids, were undertaken. The analysed soils have values of the Atterberg limits coherent with the grain size and mineralogy, and the geochemical behavior of the elements analysed is compatible with the pedogenetic processes of formation of these profiles.
