Quartz veins are fractures in the rock that are filled with quartz and other minerals. They are commonly found in areas where there has been significant tectonic activity, such as mountain-building or faulting. Quartz veins can be a valuable source of gold and other precious metals.
Quartz is everywhere. Every white grain of sand is quartz.
Quartz syenite typically contains between 5% to 20% quartz. However, in some classifications, it can be noted that quartz may comprise up to about 30% of the rock's composition. The defining characteristic of quartz syenite is that it has a higher proportion of alkaline feldspar compared to quartz, which differentiates it from more quartz-rich rocks like granite.
The subgroup for quartz is silicates.
Amethyst is a violet form of quartz.
