The association of gold with quartz forms one of the most common types of primary gold types. Veins and reefs of quartz that bear gold can occur in many types of rock, for example, around granitic rocks , volcanic rocks and in regions of black slate, but quite often these host rocks are not the immediate source of gold Ralph, 2003.
