The main types of quartz are: crystal, vein quartz and quartzite
The purest quartz crystal is called crystal. Its outer shape is a hexagonal column cone, colorless and transparent, or dyed with trace elements to a certain color. That is to say, crystal is a kind of quartz, which is not rich in nature and produces very little.
In the process of quartz mineralization, except for a very small amount of silica crystals, a large amount of silica hot water solution fills the cracks in the rock, and after condensation, it becomes dense massive crystalline quartz, which is produced in veins. Out, it is vein quartz. Vein quartz has high silica content and few impurities.
Sandstone cemented by a single silicic acid gel undergoes metamorphism and dehydration, and the quartz particles in it recrystallize and grow. This state of quartz is called quartzite. Quartzite contains a certain amount of impurities.
