| Abstract: | Despite uncertainties about the process by which 10Be may be intercepted before entering the solum and eroded after incorporation, a minimum age may be calculated for the regolith. This calculation suggests that this residual profile developed during a period no shorter than 8 x 105 yr. The calculated minimum age may be within a factor of 2 of maximum-age estimates based on surface lowering by erosion and on the rate of rock weathering to saprolite. The vertical disbution of 10Be in the profile could result from a steady-state balance of deposition, weathering, radioactive decay, and erosion.-from Authors |
