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 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.

Zielsetzung und Themenschwerpunkte (Objectives and Key Themes)

This thesis focuses on a detailed geological and petrochemical study of the Gwon-Gwon pegmatite field, located in Wamba, Nasarawa State, Nigeria. The objectives of the study include characterizing the geological setting, examining the petrography and mineralogy, and analyzing the geochemical characteristics of the pegmatite.

• Understanding the geological processes involved in the formation and emplacement of the Gwon-Gwon pegmatite field.
• Investigating the petrographic and mineralogical features of the pegmatite, identifying the different mineral assemblages and their significance.
• Analyzing the geochemical characteristics of the pegmatite, particularly the major and trace element composition, to determine its genesis and economic potential.
• Assessing the economic potential of the Gwon-Gwon pegmatite field for the extraction of valuable minerals.
• Providing insights into the geological evolution of the study area and the role of pegmatites in the regional mineralization context.
