Answer 1

Нет, кварц не является самой горной породой, это минерал.
Просто большинство горных пород состоят из него.

Кварц - один из самых распространенных минералов в земной коре, породообразующий минерал большинства магматических и горных пород.  

Answer 2

Is Quartz a Type of Rock?

Yes, quartz is a mineral and a major constituent of many rocks. It is a hard, crystalline mineral composed of silicon and oxygen atoms. Quartz is the second most abundant mineral in Earth's continental crust, behind feldspar. It is often found in igneous, metamorphic, and sedimentary rocks. Quartz can be found in various forms, including massive, crystalline, and cryptocrystalline forms such as agate, jasper, and chalcedony.

Composition and Characteristics of Quartz

- Quartz is composed of silicon and oxygen atoms in a continuous framework of SiO4 silicon–oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO2. - The typical percentage of quartz in rock is as follows: - Granite: 20-60% - Sandstone: 90-95% - Shale: 20-30% - Limestone: 5-10%.

Industrial and Commercial Uses of Quartz

Quartz has a wide range of industrial and commercial uses due to its unique properties: - It is used in the production of glass, ceramics, and concrete. - Quartz is also a key component in the manufacturing of electronics and optical instruments due to its piezoelectric and optical properties. - In the form of high-purity quartz, it is used in the production of semiconductors, solar panels, and other high-tech applications. - Additionally, quartz is used in the production of various types of jewelry and ornamental stone.

Conclusion

Quartz is indeed a mineral and a major constituent of many rocks. Its unique properties and abundance make it a valuable resource for various industrial and commercial applications.
