Resumen

OLIVEIRA BARBOSA, Inara; PINTO COELHO LACERDA, Marilusa  y  ROLIM BILICH, Marina. Soils distribution model based on relation between geology, geomorphology and pedology, at the High Plateau of Distrito Federal, Brazil. Rev. Asoc. Geol. Argent. [online]. 2010, vol.66, n.4, pp. 569-575. ISSN 0004-4822.

Studies of the relation between geology and geomorphic surfaces are important for understanding the soil distribution in the landscape. In the Distrito Federal the scale survey does not evidence some pedologic features. This study aimed to generate a pedological distribution model in Distrito Federal High Plateau with more detailed scale, from the relations between geology, geomorphology and soils. The study area is located in the midwest portion of the Distrito Federal. To generate the soil map it was used geoprocessing tools (GIS) supported by field checking. The soil map was obtained from crossing the geoforms (hypsometric and slope) with the geology map. The established pattern of soil distribution in the Distrito Federal High Plateau was shown to be representative. The study allowed establishing the relations between the soil classes with geomorphology and defining altimetry classes, slope and geology on the soil occurrence.
