Crusher Oxidized Quartz Vein
Gold Ore
Gash veins were opened up at about 90° to the strike faults, probably in areas prestressed by the folding. These veins flattened and tightened as they extended away from the initial break. The openings so produced provided channels for the passage of hydrothermal fluids containing quartz, potash, iron sulphide, tourmaline, gold and other minerals.

An oxidation zone and a transition zone, from near total oxidation to only sulphides, have been defined. Veins can be only sulphides or sulphides with white quartz. Pyrite plus arsenopyrite (or arsenical pyrite) and quartzpyrite veins are common, within the overall NE trending zone of mineralization.
