Rare Element Pegmatites - ProExMin - Prospecting ...

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. Granite pegmatites occur as dykes, lenses ...

Pegmatite - Mining Fundamentals

Pegmatite is a common, intrusive igneous rock bearing a crystalline structure that is made up of interlocking crystals of larger than 2.5cm in size. Pegmatite rocks are characterized by their exceptionally large and varying grain size. Pegmatite is a plutonic rock with a variable texture and coarseness, and abnormally large crystal sizes.
