KBS Tuff

The KBS Tuff (Kay Behrensmeyer Site Tuff) is an ash layer in East African Rift Valley sediments, derived from a volcanic eruption that occurred approximately 1.87 million years ago (Ma). The tuff is widely distributed geographically, and marks a significant transition between water flow and associated environmental conditions around Lake Turkana shortly after 2 Ma. The KBS Tuff has been described as "the Turkana Basin’s most celebrated tephrostratigraphic marker."
