Abstract. The PanAfrican belt of central northwest Africa is part of the Transaharan belt (Cahen et al. 1984) and has been interpreted by Black et al. (1979) and Caby et al. (1981) as a collision belt formed during a Wilson cycle.
New petrological and metamorphic constraints from three PanAfrican mobile belts across the main collisional suture zone that separates East and West Gondwana are presented. These include: (a) the Wadi Kariem area in Eastern Desert of Egypt, (b) the Wadi TabaElKid in Sinai, Egypt and (c) Western Dronning Maud Land, East Antarctica.
possible PanAfrican arc were several often fault bound PanAfrican volcano sedimentary sequences which latter evolved to schist belts among which is the IfeIlesa schist belt of southwestern Nigeria. The Nigerian sector consists of two main areas: the Beninian gneisses and migmatitegneiss. The gneisses
litic series of the PanAfrican Mobile Belt and the transi tion zone between the Congo Craton/PanAfrican Mobile Belt seems to be characterized by a fault which is com posed by recurrent faulting [13]. The previous studies using geophysical techniques [46] covering the east ad jacent area Akonolinga/AbongMbang has brought forth

Pan African Minerals has very healthy cash reserves and is debt free providing a platform to continue value adding activities across projects within its portfolio. The company also continues to actively seek other high quality exploration growth opportunities predominantly in gold, diamonds, copper, cobalt ore, coltan, tin, platinum, coal, oil and gas.
Several latecollision and intraplate features are not entirely integrated in the classical plate tectonic model. The PanAfrican orogeny (730–550 Ma) in Saharan Africa provides some insight into the contrasting behaviour of cratons and mobile belts.

(2001) have suggested that the Saldania Belt is a poorly exposed PanAfrican lowgrade, generally greenschist facies, orogenic belt and is a continuation of the northern Gariep Belt and Vanrhynsdorp basin. The Saldania Belt formed during predominantly sinistral transpressional tectonics and associated accretionary tectonics.
Industrial Minerals Zambia is favoured with considerable resources of feldspar (PanAfrican pegmatite bodies), silica sand (Muvaage quartzites), limestone (mostly lower Katanga), and a variety of rock types potential suitable for dimension stone.

Generally, the West African craton is bounded to the east and southwest by PanAfrican mobile belts. Outcrops of the Birimian terminate against the Liberian cratonic nucleus in western Ivory Coast. In southeast Ghana, the PanAfrican orogeny has thrusted the .
The stress configuration and tectonic analysis of the Pan – African orogeny is drawn from the Igarra schist belt, southwestern Nigeria. The analysis of conjugate shear fractures of the schist belt indicates that two distinct compressive events (NE – SW and E – W) occurred in this Pan – African mobile zone.
