Geology and petrochemistry of Gwon-Gwon pegmatite field Wamba Nasarawa state

Master's Thesis from the year 2011 in the subject Geography / Earth Science - Geology Mineralogy Soil Science Abubakar Tafawa Balewa University language: English abstract: Pegmatites are coarse grained igneous and metamorphic rocks. They represent the end product of magmatic stage in the evolution of granitic melt. The rare-metals (rare-elements) that serve as petrogenetic indicators (geochemical indicators) and potential ore indicators are Rb Cs Li Sn Ta Nb Be and W also volatiles like BFH2O play a very important role in the whole process. Pegmatites research in Nigeria from 1946 to 1989 by Jacobson and Webb ( 1946) and Matheis and Kuster (1989) Matheis(1989) Matheis and Cean- Vanchette ( 1983) use the rare-elements as tin indicators but petrology was not the main target.
