- •
The Kelso Dunes of desert California have a complex geomorphology
- •
Past studies suggest the dunes are quartz-rich, derived from the Mojave River
- •
The dunes are much richer in K-feldspar than previously supposed
- •
Alluvial sources can be distinguished using K/Rb and K/Ba in K-feldspar
- •
The dunes have a complex origin, with possibly three alluvial sources
- •
Methods employed here could be applied to dune provenance studies worldwide
