What are quartz characteristics?
Quartz is a naturally occurring silicate mineral composed of silicon dioxide (SiO 2 ). Its hardness is 7 on the Mohs scale and it is in the trigonal crystal system. Quartz pos…sesses a glassy luster and does not exhibit cleavage. The average specific gravity of quartz is 2.62. Quartz can be found in all three rock types, igneous, metamorphic, and sedimentary. Quartz has a white streak, but specimens can be appear colored by impurities or exposure to heat or radiation to hues of white, pink, red, orange, yellow, blue, green, black, smokey, milky, or purple. Quartz is a mineral, chemical composition of silicon dioxide, one of the most common minerals on the planet.

Quartz is a naturally occurring mineral and may be found in all three types of rock. Quartz in found in the ground. It is a common constituent of granite, sandstone, limeston…e, and many other igneous, sedimentary, and metamorphic rocks. It is the most abundant mineral in Earth, therefore, you can find quartz almost everywhere.
Quartz is the second most abundant mineral in the Earth's continental crust, after feldspar. It is made up of a continuous framework of SiO 4 silicon--oxygen tetrahedra, wit…h each oxygen being shared between two tetrahedra, giving an overall formula SiO 2 . There are many different varieties of quartz, several of which are semi-precious gemstones. Especially in Europe and the Middle East, varieties of quartz have been since antiquity the most commonly used minerals in the making of jewelry and hardstone carvings
Most sand grains are of quartz.\n \n
quartz is..... 1. smooth 2. shiny 3.a mineral
El cuarzo tiene un efecto piezoelÃ©ctrico lo cual le permite crearlos impulsos necesarios para la mediciÃ³n del tiempo en intervalosregulares, que por lo general es alimen…tada por un campo elÃ©ctricooscilante.
Pure quartz is crystal clear, it will still refract (bend) and reflect light. It was pure crystals of quartz that gave rise to the expression "Crystal clear,"
"Shapeless" quartz is usually associated with tectonic movements and metamorphic rocks. In granites it is about the last mineral to crystallise and it fills the spaces between… the micas and feldspars. In a crystalline form it forms long hexagonal (six sided) usually clear transparent crystals which are topped off with a hexagonal pyramid
No, we call something mafic if it has a relative low silica content. As quartz is 100% silica, it's not mafic, but felsic.
If Topaz can scratch quartz but topaz can be scratch by a diamond What mineral characteristics does this relate to?
It is the absolute silicate. All other silicates have greater amounts of silicon and oxygen along with other minerals.
Something as common a quartz would probably not be priced for its quality, but its quantity would have a price. The reason diamonds are so expensive is because they are so har…d to find.
Probably, quartz is in quite a few mountains.
during heat prusure and time it changers from quartz to smoky quartz
Chemically it is Silica - Silicon Dioxide - the main constituent of glass. \n. \n. Quartz is piezo-electric and was used in early sonar transducers, but modern sonar uses sy…nthetic ceramics that are far more sensitive and efficient. (NB: don't be taken in by the purveyors of quartz "healing crystals" who seem to have latched onto this property: their claims for it are pure fraud.) \n. \n. Decoratively, silica is the base part of semi-precious mineral compounds (metal-silicates).
