Mineralization types in the Mozambique Belt of eastern

Oct 01, 1994 Various mineral deposits representing different mineralization types are found in these Paleoproterozoic rocks of the Mozambique Belt in Eastern Zambia (Table 1). Although there are no major mines in the area as a whole, a number of small mines have been worked in the past and new ones are currently in operation.

Mineral deposits in Kenya occur in different geological settings, such as those associated with Tertiary rocks (Turkana sapphire deposit). Most of the mineral deposits like iron ore located within the Neoproterozoic Mozambique orogenic belt have not been properly evaluated in geological and metallogenical context.
