Abstract
Two toposequences derived from granite in the Mt. Garnet area, North Queensland, were examined to determine the detailed soil - landform relationships in order to facilitate subsequent broad-scale mapping of the soil resource. The dominant landsurface feature is gently sloping, concave footslopes covered by relatively thick colluvial deposits. It is assumed that these footslopes are attributable to a retreating midslope as well as the colluviation of materials during dry periods of the Late Mid- to End-Pleistocene. Granulometrie parameters indicated a single source of parent material for the footslope soils, although there would seem to be a temporal discontinuity between the A and B horizons. The distribution patterns of the footslope soils (varying from Griffin, Shepstone to Longlands forms) could be explained by means of a simple catenary model, in which profile hydrology, caused by a water surplus generated by the physical environment, played the major role. In extent, the footslope is dominated by th...
