Popis: The concentrations of long-lived cosmogenic nuclides (¹⁰Be, ²¹Ne, ²⁶Al) in quartz obtained from a very recent (~200 a) river terrace in Namibia are nearly constant throughout a 322 cm long depth-profile. These findings corroborate earlier hypotheses postulating a homogeneous distribution of these nuclides in freshly-deposited river terrace sediments. An averaged nuclide concentration is a crucial and generally assumed prerequisite for the determination of numerical ages of old sediments.
