List Minerals Associated with Gold

To know what type of rock is with you must see that the most common in placer deposits are platinum, iridosmine, magnetite, iron pyrites, ilmenite, zircon, garnets, rutile and barytes wolfram, scheelite, brookite and diamonds are less common. Diamonds are with in Brazil, and also occasionally in the Urals and in the United States. In auriferous quartz ...

    A wide variety of form through hydrothermal activity, but seafloor massive sulfides are formed from reduced sulfur and may be enriched in copper, zinc, iron, , and silver. Hydrothermal vents exist along mid-ocean ridge spreading centers, extensional systems with subduction zones, volcanoes, and intraplate hotspots.

    Gold often occurs in free elemental native form, as nuggets or grains, in rocks, in veins, and in alluvial deposits. It occurs in a solid solution series with the native element silver as electrum, naturally alloyed with other metals like and and also as mineral inclusions such as within pyrite.
