Geoarchaeology at Gi, a middle stone age and later stone age site in the Northwest Kalahari

Dates for the Middle Stone Age of East Africa
Science, 1975Three potassium-argon age determinations on sanidine from crystalrich pantellerite and volcanic ash in the Main Rift Valley of central Ethiopia indicate that the Middle Stone Age of East Africa began prior to 180,000 years ago. This suggests that the technological developments which characterize the Middle Stone Age have a far greater antiquity than ...
