The Great Rift Valley as it is visible near Eldoret, Kenya. The Great Rift Valley is a geographical and geological feature running north to south for around 4,000 miles (6,400 kilometers), from northern Syria to central Mozambique in East Africa. Astronauts say it is the most significant physical detail on the planet that is visible from space.

Fluorspar is the second most important mineral in Kenya. It is mined at Kimwarer in the Kerio Valley of the Rift Valley. The rocks containing the minerals are dug up using the open cast method and crushed using large grinders. The crushed rock is then mixed with chemicals to separate fl uorspar from rock wastes.

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 ...

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.
