  he Sn-(Nb, Ta) mineralization of the Wamba field (central Nigeria) occurs in muscovite-quartz-microcline pegmatites, which are related to the late-orogenic Pan-African (f Ma) "Older Granites".

Nigeria’s population is projected to grow from more than million people in to million in , becoming the world’s fourth most populous country. Nigeria’s sustained high population growth rate will continue for the foreseeable future because of population momentum and its high birth g: pegmatites.

Late Pan African ages ( Ma) have been recorded for the rare metal pegmatites of central and southwestern Nigeria[37] suggesting emplacement during the end of Pan African Magmatic activity. The mineralised pegmatites have generally been regarded as late stage residual fluids of the common Older Granites in the basement Size: KB. The pegmatitesof Nasarawa area occur in the central part of Nigeria. They are mainlyhosted by phyllonites in a NNE-SSW trending shear zone lying east of somefoliated Pan-African and West of Jurassic Afu ComplexYoun-. The Precambrian Basement Complex of Nigeria consists of migmatite, gneiss, metasediments and metavolcanics that have been intruded by Pan-African Granitoids which consist of granites, gabbros, charnokites, diorites, syenites, dolerites and pegmatites (Wright, , McCurry, , Kinnaird, , Dada et al., ) while the north central area of the crystalline basement of Nigeria has witnessed Cited by: 1. eral oliversity of gemstone raremetal pegmatites besides colorful tour-maline. The Lipovskoye pegmatite field, usually called “Lipovka” for short, is located in Rezh district of Sverdlovsk Oblast in Central Urals. It is 70 km to northnortheast from Ekaterinburg city and in 20 km to northwest from town of Rezh.
