Quartz Stone Varieties And Identification

The 60% of the crystal is "silicon dioxide" (sio2)


the color of the crystal is due to the addition of silicon dioxide, but also contains a variety of different amounts of metal caused. In the natural environment, the majority of the crystal will be with the mineral calcite, pyrite, glibenite, a variety of colors of mica, Pixian, granite, rutile and other "symbiotic", and the formation of some suspicious real scene, The so-called "vision crystal", an increase of the collection of crystal fun and value.

Most of the crystal is grown in the ground, the growth process requires a large amount of saturated silicon dioxide containing groundwater source, the temperature between 550-600 ℃, and the need for atmospheric pressure greater than twice to three times the pressure, after a long time , It becomes a hexagonal (hexagonalsystem) crystal.


Quartz is a kind of mineral which is easy to become liquid when heated or pressed


Is also quite common rock mineral, in the three major types of rocks are there. Because it is the largest in the igneous rock, so usually the lack of complete crystal face, mostly filled in the other first crystallization of rock-forming minerals in the middle. The composition of quartz is the simplest silicon dioxide (sio2), glass luster, no cleavage surface, but with shell-like fracture. Microcrystalline quartz is called chalcedony, agate or jasper. Pure quartz is colorless, but often contains different elements of transitional elements with different colors. Quartz is very stable, not easy to weather or change for his kind of minerals.
