Overview Pegmatite quartz refers to high-purity quartz formed in pegmatite. Pegmatite is a special granite rock, usually composed of coarse to huge quartz crystals. The quartz in these rocks usually has a larger crystal size and a lower impurity content. Formation process of pegmatite quartz The formation of pegmatite quartz is a complex process inside the earth, involving many geological processes such as magmatic activity, metamorphism, and tectonic movement. Next, we will discuss this process in detail from different angles. Magmatic activity and the formation of pegmatite quartz The formation of pegmatite quartz is closely related to magmatic activity. During the intrusion evolution of magma, due to changes in temperature, pressure and other conditions, hydrothermal fluids rich in SiO2 are differentiated. These hydrothermal fluids penetrate into the surrounding metamorphic rock system along the bedding and cracks, or invade along the contact fracture zone of the previous magmatic rock to form vein quartz ore bodies. Metamorphism and the formation of pegmatite quartz The hydrothermal fluid produced by regional metamorphism or mixed lithification is also an important factor in the formation of pegmatite quartz. Strong magmatic activity and tectonic movement provide heat sources for metamorphism. When water-containing igneous rocks and basement protoliths are metamorphosed, a large amount of water is released to form metamorphic hydrothermal fluids. These ore-bearing solutions migrate along the ductile shear zone under the action of tectonic stress. Due to changes in temperature and pressure conditions, SiO2 is supersaturated and deposited to form vein quartz. Tectonic environment and the formation of pegmatite quartz The formation of pegmatite quartz is closely related to a specific tectonic environment. For example, pegmatite deposits are formed in a stable tectonic environment at the top of granite, formed by the recrystallization of the surrounding granite and the decomposition of the mineral components that make up the granite. Details of the formation of pegmatite quartz The details of the formation of pegmatite quartz can be revealed by studying the fluid inclusions inside it. Fluid inclusion microscopic analysis shows that in the process of wall crystallization, the brine H2O-NaCL-KCL-(CO2,N2) type fluid (about 20wt.% NaCL and about 3wt.% KCL) is saturated, and in the process of magmatic hydrothermal crystallization, multiphase cassiterite mineralization forms large microcline crystals in the wall belt, and is combined with quartz, F-poor black mountain rock, and carbonate- and boron-rich manganese fluoroapatite in the core area. World distribution Pegmatite quartz is a high-quality quartz resource. Due to its special formation environment and purity, it has extremely important applications in industry and high-tech fields.
