| Zusammenfassung |
| Low, flat terrain (slope 400 kyr) implied in the ‘storage’ hypothesis. The 26Al/10Be ratio has
been used to identify a complex exposure history, such as one including burial,
where a lower offset in 26Al/10Be ratio from the expected production-rate ratio of
6.8 can be converted to a burial age. Eleven detrital samples were collected along
the full length of the Cooper, plus three surface samples from source-bordering
dunes in the lowermost reach. We discuss our preliminary findings with regard to
sediment burial and long-term interactions in the river-dune systems of central
Australia.
