The Utilization of Cryptotephra to Refine the Age Model at Archaeological Site Kathu Pan 6

Cryptotephra (microscopic volcanic ash) has had significant contributions towards constructing and refining age models and correlating archaeological sites for decades. This thesis will report on cryptotephra from the archaeological site of Kathu Pan, specifically from sinkhole 6, located on the southern edge of the Kalahari basin in the Northern Cape of South Africa. I will investigate the potential of cryptotephra from the Holocene layers of Kathu Pan (KP6) to test the current age model and source it to a specific region and a specific eruption. Both of the samples in this study, kp6-55-70 and kp6-75-90, are high silica rhyolites that date to the Holocene. Based on the geochemical findings, both samples have potential to be sourced from the Main Ethiopian Rift (MER), Guatemala, Indonesia, and New Zealand. The primary sourcing was focused on the Main Ethiopian Rift (MER) and the Turkana Basin in Kenya. Evidence suggests that kp6-75-90 is likely to have originated from the Turkana basin, meanwhile kp6-55-70 requires further sourcing in order to confidently correlate it to a region and an eruption. Further research needs to be completed in order to refine the age model at Kathu Pan 6.
