At the surface, the Congo and Kalahari Cratons are separated by the Damara Province, a ∼400-km-wide Pan-African mobile belt . Whereas Pan-African rocks throughout the rest of Africa are underlain by a low wave speed upper mantle and lithosphere too thin to be resolved with the long-period surface wave analysis we employ, the Damara mobile ...

Westafrica Mineral Mining Ltd 4. Mineral Potential of the MSGBC Basin The Archean domain contains most of the iron-ore reserves of the West African Craton, with large ferriferous quartzite/banded ironstone deposits (BIF). It also contains many deposits of Cr, Ni-Co associated to the greenstone belts and/or layered basic to ultra mafic
Lower crustal sections (granulite domains) within the Pan African belts are also strongly depleted in mineral deposits relative to the upper crustal sections of juvenile Neoproterozoic terranes. A depletion factor for all terranes in Pan African orogens is derived with which to evaluate the role of mineral deposit recycling during orogenesis.

The sedimentary sequence in the Volta Basin rests unconformably on the Eburnean basement complex. This basement and its cover constitute the western “Stable Zone” of our study area (with rock assemblages that did not undergo the Pan-African thermotectonic events); the eastern “Mobile Zone” is represented by the frontal part of the Pan-African Dahomeyide Orogenic Belt (Figures 1 and 2).
Within the West African Craton, there is a large amount of mining activity covering resources such as gold, copper, cobalt, silver, tin, and zinc. Artisanal mining activity in the craton dates back to the early 1960s which used quartz vein debris as a gold indicator.
Based on a broad review of literature and new data, 5 stages of geological-tectonic development have been identified. For the first time a systematic review of the mineral potential of the Pan-African Volta Basin was executed.

forms part of the Pan-African mobile belt and lies between the West-African and Congo Cratons and South of the Tourareg Shield. The rock sequence in this area according to Olanrewaju 1981; are mainly granites, charnockites and medium-grained migmatites. These rocks bear imprints of the Proterozoic Pan-African orogeny (600 ±150 Ma)

In the Neoproterozoic, Ghana was affected by the Pan-African orogeny. Today, the Pan-African mobile belt terrane spans eastern and southeastern Ghana, with several different units. The Dahomeyan System comprises both mafic and felsic gneiss while the Togo Series includes quartzite, shale and small amounts of …
of the eastern flank of the Ife-Ijesha schist belt of Nigeria with the aim of delineating structural and geological conditions relating to mineralization within the study area. 1.1 Geology and Description of the Study Area The basement rocks of Nigeria is part of the extensive Pan-African Province of West Africa and are delimited in the west
Abstract. The gold and base-metal potential of the Pan-African orogens is reviewed. Explorationists in these terranes face two scenarios: ground that has already been explored but merits re-evaluation in the light of new techniques or data, such as the Central African Copperbelt and the Damara Belt, and ground that has been subject to little previous exploration, such as the Mozambique Belt ...
Pan-African mobile belts. Despite superficial cover, which obscures deeper tectonic relationships, the Damara Belt appears to link up, in a northeast direction, with the Pan-African Katangan/Lufilian Arc system of Central Africa. The orogen can be divided into a number of distinct zones
Abstract Available isotopic and geochronological data, combined with new petrographic and structural observations in Cameroon, permit discussion of the nature and extension of the Paleoproterozoic West Central African Belt, which resulted from the Eburnean collision between the Congo and São Francisco cratons.
The southern part of the Transaharan mobile zone is rep- resented by the Pan-African Dahomeyide orogenic belt . This orogen overthrusts the Neoproterozoic cover constituting the eastern part of the Volta Basin or its Eb- urnean substratum of the Leo-Man shield [22-25]. This collisional belt consists of several lithostructural units
Orogenic belts comprising the Pan-African system include: The Arabian-Nubian Shield, extending from Ethiopia to the southern Levant, it is associated with the opening of the Red Sea.; The Mozambique Belt, extending from east Antarctica through East Africa up to the Arabian-Nubian Shield, formed as a suture between plates during the Pan-African orogeny.

environment and a high potential for economic mineral deposits, due to its position within the extensive Pan-African mobile belt separating the West African and Congo cratons. In neighboring countries, the Pan-African mobile belt is often associated with a number of world-class deposits. Prior to the emergence of the petroleum industry 30 years
Africa contains an enormous wealth of mineral resources, The oldest mobile belts are found in Archean rocks, such as the Limpopo belt separating the Kaapvaal from the Zimbabwe craton. The end of the Precambrian was marked by a major event of mobile-belt formation known as the Pan-African episode (about 950 to 550 million years ago), Check price
