Description :
Sites in the Blue Mountains show a sharp decrease of soil depth where vegetation changes from forested plateau surfaces to heath-covered spurs, and bands of bare rock in the heath suggest that soil production depends on soil presence of a finite depth of soil. The substrate varies from hard ferruginized sandstone to soft saprolite. In situ Be 10 determinations indicate that apparent rates of erosion and soil production are greater under the relatively thin heath soil than under the thicker forest soil but, in contrast to other studies, these sites do not show significant depth-dependence of apparent soil production.
