Significant amounts of gold have come from Alabama, making it one of the better gold producing states east of the Mississippi River. Gold has been found in both lode and placer deposits, with the majority coming from area in the east central part of the state up next to the Georgia border.
Answer (1 of 12): No they do not. Quartz is common, gold is rare. Quartz veins typically form when very hot water rising from depth flows into a shallow crack in the rock. The dissolved silica precipitates as quartz. If there is gold present in the water, it will also precipitate. The result is
These color changes can be an indicator of gold because gold often occurs in altered rocks or along rock contacts. 17) Iron Staining & Gossans. Not all veins produce much quartz.
