What is a crystal?
Crystal is a rare mineral, quartz crystal, the main chemical composition is silicon dioxide, the chemical formula is SiO2.
Pure silica is a colorless and transparent crystal. When it contains a small amount of impurity elements such as Fe, Ti, and AI, it will show different colors, such as yellow, purple, smoke, pink, etc.
Crystal formation
The formation conditions of crystal are more severe than that of ordinary quartz.
First, there needs to be enough and stable growth space; secondly, there must be hydrothermal fluids rich in siliceous minerals, which are slightly alkaline and have low salinity; thirdly, appropriate temperature (1600℃-4000℃) , Appropriate pressure (2-3 atmospheres); Fourth, a certain growth time is required. Only when these four conditions are met can crystals be generated.
Crystals are often produced in the form of crystal clusters and geodes, among which crystal caves generally exist in igneous rocks and basalts of huge lava flow layers formed by volcanic eruptions. The gas contained in the volcanic eruption or the dissolution of hot water causes a large number of pores in the rock formation. When the fluid rich in siliceous minerals enters the thin lava pores, and the temperature and pressure conditions are suitable, crystals will precipitate out of crystals, etc. mineral.
Types of crystals
There are many types of crystal stones, not only the difference in color, but also because of the different elements contained, but because of the beautiful color, people like to wear crystal as jewelry, and give crystal various meanings. , Next, let me introduce some types of crystals!
