Optically Stimulated Luminescence (OSL) dating and palaeoenvironmental studies of pan (playa) sediment from Witpan, South Africa

Abstract:

Robust, dateable sources of palaeoenvironmental proxy data are scarce in the southwestern Kalahari Desert, and this study investigates the potential of pan (playa) floor sediments as an archive of late Quaternary environmental change. Augering has revealed the presence of up to 3 m of clay- and silt-rich deposits in the base of Witpan, a small pan basin set amongst linear and lunette dunes. The weakly-stratified deposits include aeolian quartz sands and evaporites amongst a clay-rich groundma...
