The Quartz Page: Occurrence
The terms "vein quartz" and "gangue quartz" are easily confused. Gangue or gang is the term for those minerals in a ore deposit that accompany the ore minerals but are of no value by themselves. Common gangue minerals are quartz, calcite and dolomite. They often occur in a layered manner that reflects the order of deposition of different minerals.
