Lithospheric thickness beneath the southern Kenya Rift: implications from basalt geochemistry

Geochemical data are reported for samples from the flanks and floor of the soutehrn Kenya Rift Valley in the Lake Magadi darea, and from two central volcanoes located within the rift valley. Rift lavas include samples of Singaraini and O1 Tepesi basalts on the eastern flank, Kirikiti basalts from the western flank, and plateau trachytes from the rift valley floor.
