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.
