Compositional and textural correlations between Olduvai Gorge Bed I tephra and volcanic sources in the Ngorongoro Volcanic Highlands, Tanzania

摘要

Tephra layers from Bed I of Olduvai Gorge, Tanzania, are correlated directly to their source volcanoes in the nearby Ngorongoro Volcanic Highlands (NVH) based on composition, texture, and age. Tephra in lower Bed I are more silicic than the upper Bed I te
