Soda lake.
Also extensive deposits of chert.
In June 1959, E.P. Saggerson and B.H. Baker of the Geological Survey of Kenya discovered a number of small alkaline intrusions in upper Tertiary lavas on the Nguruman Escarpment, which form the western wall of the Rift Valley about seventy miles southwest of Nairobi. During a detailed examination of these intrusions in 1960, they found the alkaline rocks to be emplaced in a flow of ankaratrite (biotite-olivine melanephelinite), that is evidently intercalated in more common olivine basalts. The intrusions, which are probably of upper Tertiary age, are closely controlled by two north-south vertical fault zones in the ankaratrite. Narrow dikes feed sills about 2 ft (ca. 61 cm) thick, which thin rapidly into an intricate network of veins.
