BeschreibungPegmatites 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 B,F,H2O 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.
