Abstract

Deposits of cobbles and boulders found hanging on midslopes of the Itatiaia Plateau reflect tectonic reactivation and a large range of climate-controlled processes, probably including frost weathering. These processes, more efficient in detaching debris from freefaces, were replaced, at the end of the Pleistocene, by colluviation. Interpretation of hillslope processes was based upon the sedimentological, mineralogical and micromorphological characteristics of colluvia. Changes in weathering characteristics and hillslope processes suggest variations in environmental conditions of the Itatiaia Plateau since the Late Pleistocene
