Magadi area include the Magadi area as described by Baker (1958), the area south of Magadi, extending to the border with Tanzania (Baker 1963), and the easternmost part of the Loita Hills area (Saggerson 1966). Much of the area lies within the rift valley the western walls of which is marked by the often spectacular Nguruman Escarpment. The rift valley floor is broken by numerous fault scarps that step inwards to a central trough that is partly occupied by Lake Magadi.

Geochronology

Mineralization age: Cenozoic : 5.13 Ma to 0.63 Ma

Important note: This table is based only on rock and mineral ages recorded on mindat.org for this locality and is not necessarily a complete representation of the geochronology, but does give an indication of possible mineralization events relevant to this locality. As more age information is added this table may expand in the future. A break in the table simply indicates a lack of data entered here, not necessarily a break in the geologic sequence. Grey background entries are from different, related, localities.
