Iron Staining & Gossans: Not all veins produce much quartz – gold bearing veins can consist of calcite or mostly sulfides – which often weather into iron stained spots when the pyrites convert to iron oxides. Large amounts of iron oxides like hematite, magnetite and ironstone can be favorable indicators.

Both magnetite black sand and hematite are oxides of iron. These are rather complex inorganic compounds that can occur in various forms. There can be valuable metals in black sands that are magnetic – for example, some of the platinum group metals can exhibit mild magnetic qualities.
