The vast area lying north of 3º00'N between Lake Turkana and the northern and western borders of Kenya has been mapped by Walsh and Dodson (1969) and includes numerous volcanic centres, the outpourings from which extend over about one third of the total area.

Approx coords range: 3º00' - 4º36'N; 34º02' - 36º00'E.

Geochronology

Mineralization age: Cenozoic : 33 Ma to 6.8 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.
