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. This region contains fractured sedimentary rocks that also contain silica, pyrite, coloradoite and other rock formations. When a body of magma is formed it is like a big pocket of primordial soup. What Is Mariposite? Very generally because the solubility of silica and gold in high temperature (hydrothermal) solutions are affected by the same thermodynamic controls at lower temperatures. This is part of gold's value. How to Identify Gold in Quartz. The native elements contain the most gold, followed by the sulfide minerals.
