Abstract :
Depth profiles of in situ-produced cosmogenic nuclides, including 10Be (T1/2=1.5×106 years) and 26Al (T1/20.73×106 years), in the upper few meters of the Earthʹs crust may be used to study surficial processes, quantifying denudation and burial rates and elucidating mechanisms involved in landform evolution and soil formations. In this paper, we discuss the fundamentals of the method and apply it to two lateritic sequences located in African tropical forests.
