40Ar/39Ar dating of Plio-Pleistocene Drill Cores from East Africa

East Africa provides the opportunity to acquire unique evidence toward understanding the influence of climate and environmental change on the evolution of the human lineage and technology during the Plio-Pleistocene. The Hominin Sites and Paleolakes Drilling Project (HSPDP) has extracted a total of 2 km of sediment drill core from the Rift Valley of East Africa, in paleolake basins adjacent to fossil hominin and archaeological sites of major significance. 40Ar/39Ar dating and chronology modeling of four of these sites will be discussed. Sites in the southern Kenya Rift will be compared to outcrop geology of the Olorgesailie area, which exhibits some of the earliest Middle Stone Age archaeology.
