Abstract

The concentrations of long-lived in-situ produced cosmogenic nuclides (10Be,21Ne,26Al) in quartz obtained from a very recent (~200 a; based on14C data on organic material) terrace of the Swakop River 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.
