BURIED SOILS AT THE PLATAFORMA BASCULADA ONDULADA (UNDULATED TILTED PLATFORM) IN CENTRAL REGION OF CÓRDOBA PROVINCE, ARGENTINA

Jorge A. SANABRIA, Graciela L. ARGÜELLO

Resumo


In the central part of Córdoba Province, inside Plataforma Basculada Ondulada (Undulated Tilted Platform), and under very special circumstances present soils are buried by loessic materials.It is interesting to establish whether these soils can be considered as paleosols or not. This paper includes some examples where the second option seems to be the right one. That is the case both along drainage lines and on eastward slopes interrupted by roads or wire fences. In Corralito gully (33º 05'W - 64º 00'S), the modern soil, namely Serie Manfredi is covered by an alluvial sediment nearly 1 meter thick, that includes rests of recent materials such as bricks, glasses and so on. On the eastward dipping slopes, along the fences, it is very common to find present soils overlain by recent materials that were deposited alongside the obstacle by hydrological fluxes. These buried soils cannot be considered as paleosols, and are therefore not as meaningful as real paleosols are. Nevertheless, they are very good indicators of anthropogenic activities and disturbances that took place much more recently.
