Goodenough, Kathryn; Lusty, Paul; Key, Roger; Garba, Abdulrazaq. 2012 Pan-African granitoids in Nigeria : petrogenesis and potential for metallogenesis. [Lecture] In: 34th International Geological Congress, Brisbane, Australia, 5-10 Aug 2012.
Nigeria is crossed by Pan-African orogenic belts, formed during the Neoproterozoic to Cambrian amalgamation of Gondwana. Within these belts are extensive post-collisional granitoid plutons, which are associated with Ta-bearing pegmatites that are mined by artisanal methods. Recent geochemical mapping by the British Geological Survey (BGS) and Nigerian Geological Survey Agency (NGSA) has identified anomalous levels of critical metals for new technologies (e.g. REE, Nb and Ta) around the post-collisional granitoids.
