Abstract

Rare-metal pegmatites are significant sources of critical minerals, including lithium, tantalum, niobium, and rare earth elements (REEs), which are essential for modern technological applications. These pegmatites, characterized by large crystals and unique mineral assemblages, provide valuable insights into the processes of magmatic differentiation and crustal evolution. The petrogenesis of rare-metal pegmatites is a complex and multifaceted process, influenced by a combination of geological, geochemical, and tectonic factors. This article presents a comprehensive study of the geochemical processes involved in the formation and evolution of rare-metal pegmatites, with a particular focus on their elemental composition, mineralization patterns, and the role of magma evolution in their petrogenesis. We explore the geochemical signatures that help define these pegmatites and discuss the implications of these findings for understanding magmatic systems and mineral exploration.
