Most of the Great Rift Valley falls in Kenya's Rift Valley Province and is said to be the most beautiful section. The Great Rift Valley, in its entirety across the African continent, is more than 6,430 kilometres (3,987 miles) long and, in places, up to 1,520 metres (4,986 feet) deep – all caused by the movement of tectonic plates and ...

Geochemistry of high-silica peralkaline rhyolites, Naivasha, Kenya rift valley December 31, 1987 The Recent (<15000 y) volcanic complex of southwest Naivasha, Kenya, consists of mildly peralkaline (comenditic) rhyolite domes, lava flows, air fall pumices, and lake sediments, with minor, peripheral, basalts and hawaiites.

Late Quaternary fluviolacustrine siltstones, mudstones and claystones (Loboi Silts) on the northern margins of the saline, alkaline Lake Bogoria in the Kenya Rift Valley contain up to c. 40% authigenic analcime and minor natrolite.

Most of the basalts occur as Miocene flows that flooded a proto-rift depression in northern Kenya. The oldest Miocene basalts comprise the Samburu, Lodwar, Mt. Elgon and Rusinga basalts. There are post-Miocene basalts of the rift floor that show affinities with lavas on the flanks of rift and resemble rocks of multicentre fields east of the rift.

In the Kenya Rift Valley, the volcanic rocks contain largely clay minerals where F-can be associated. Under the alkaline conditions with elevated HCO 3 − contents, HCO 3 − would compete with F ¯ for the sorption sites in the clay minerals and enable the adsorbed F - to be desorbed and entered into groundwater ( Gao et al., 2009, Su et al ...

Lake Magadi, East African Rift Valley, is a hyperalkaline and saline soda lake highly enriched in Na+, K+, CO32–, Cl–, HCO3–, and SiO2 and depleted in Ca2+ and Mg2+, where thick evaporite deposits and siliceous sediments have been forming for 100 000 years. The hydrogeochemistry and the evaporite deposits of soda lakes are subjects of …

The Kilombe (or Eldalat) caldera volcano is situated on the western inner flank of the Kenya Rift Valley at the junction of the Kenya and Kavirondo rifts (35°50′E, 0°05′S; Fig. 1). It has a volume of 15 km 3 and is formed almost entirely of trachyte lavas and pyroclastic flows (McCall, 1964). Trachytic tuffs partially fill the caldera and ...

The East African Rift (EAR) is an active continental rift zone in East Africa. The EAR began developing around the onset of the Miocene, 22–25 million years ago (Ebinger, 2005). In the past, it was considered to be part of a larger Great Rift Valley that extended north to Asia Minor. The rift

Further eruptions accompanied by faulting persisted and also gave rise to the Rift Valley and the volcanic piles of Mounts Kenya, Elgon and Kilimanjaro. Quaternary volcanism was mostly within the Rift Valley and has given rise to the craters and cider cones that are found in the floor of the valley e.g. Longonot, Menengai and Suswa. 5.
