Specialty Definitions: Pegmatite

Domain	Definitions
Geological	An igneous rock with very large (usually > one inch), well-formed crystals. A granitic pegmatite has the mineralogy of a granite and abnormally large grains, whereas a gabbroic pegmatite has the mineralogy of a gabbro and very large grains. An intrusive igneous rock. (Plank and Schenck, 1998). (references)
	A very coarse-grained igneous rock, commonly with a granitic composition. Usually forms from molten rock rich in water or other volatiles that facilitate the growth of large crystals. Forms sills and dikes. (references)
Mining	An exceptionally coarse-grained igneous rock, with interlocking crystals, usually found as irregular dikes, lenses, or veins, esp. at the margins of batholiths. Most grains are 1 cm or more in diameter. Although pegmatites having gross compositions similar to other rock types are known, their composition is generally that of granite; the composition may be simple or complex and may include rare minerals rich in such elements as lithium, boron, fluorine, niobium, tantalum, uranium, and rare earths. Pegmatites represent the last and most hydrous portion of a magma to crystallize and hence contain high concentrations of minerals present only in trace amounts in granitic rocks. Adj: pegmatitic. Syn:giant graniteCF:symplectite. (references)

Specialty Definition: Pegmatite

Pegmatite is a very coarse-grained igneous rock having a grain size of 20 mm or more; such rocks are referred to as pegmatitic.

Most pegmatites are granite with quartz, feldspar, and mica. Pegmatites are important because they often contain other rare earth minerals and gemstones, such as aquamarine, tourmaline, topaz, fluorite, apatite, tin, and tungsten, among others.

Granitic pegmatites, boron granitic pegmatites, lithia pegmatites, and boron lithia pegmatites exist.
