  • Rare Element Pegmatites - Prospecting Exploration

    Pegmatites enriched in rare elements are holocrystalline rocks composed of igneous rock-forming minerals, typically of granitic composition and by their highly variable grain size, including extremely coarse crystals. They are considered to form by fractional crystallization from the residual melt highly enriched in incompatible elements and volatiles.
