I have seen pegmatites used for rip rap along coasts to build jetties and dikes to prevent erosion or sedimentation along canals and embayment mouths that are prone to sedimenting up due to long shore current. In the early stages of crystallization, the ions that form high-temperature minerals are depleted from the melt. Heat, pressure, impact, water, scratch, stain, acid, and wind. A pegmatite is an igneous rock, formed underground, with interlocking crystals usually larger than 2.5 cm in size (1 in). Pegmatite rocks are a great source of construction aggregates, road aggregates, and as a base material in landscaping &, Besides these, the applications of pegmatites are known as the building stones, facing stones, and. 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. This allows them to move about freely and form crystals rapidly. Some Magma comes out on the surface of the earth while some remain beneath the ground or crust of the earth. Chaper found diamond with corundum in a decomposed red pegmatite vein in gneiss. The most interesting thing during the igneous rock formation is the speed of cooling and crystallization of various minerals existing in the magma as well as in the surrounding substances/rocks/stuff of the earth. Pegmatite is the host rock for many rare mineral deposits. Pegmatites may be composed of a variety of minerals. We know magma is a complex suspension. The term “Pegmatite” was first used by a French mineralogist René Haüy for “Graphic Granites” like rocks. Graphic granite is characterized by minerals that form shapes resembling writing. When instantaneous cooling of lava takes place, so, mineral grains formation cannot take place and result directly into the glass formation. Because these dikes and pockets are small in size, the mining operations that exploit them are also small. Crabtree pegmatite: One of the most interesting pegmatites is the Crabtree Pegmatite of western North Carolina.
