“…In Brazil, Pedological and Geomorphological research highlighted the evolution of landforms by defining the autochthonous and allochthonous nature of materials (FEUER, 1956;BIGARELLA et al, 1961;AB'SÁBER, 1962;BENNEMA et al 1962;BIGARELLA et al, 1965;CARVALHO et al, 1969;COUTARD et al, 1978;DIAS FERREIRA et al, 1978). Some criteria were employed to define allochthony and autochthony through a study of superficial formations, such as the presence of stone-lines with or without ferruginous concretions, which would differ from the geological substrate and follow the slope profile, as well as the marked differences in the mineralogical composition or chemical properties of successive horizons, and the presence of buried horizons rich in organic matter and evidencing the presence of paleosols (QUEIROZ NETO, 2001).…”
