It may also form in veins formed along major fault zones. Gold in veins is associated with sulfides, quartz, and calcite. Gold is resistant to weathering, hence is often freed from the surrounding rock and redeposited as sediment. Because gold has a high density, it tends to settle out readily and be trapped with coarser sediments.
To know what type of rock is gold associated with you must see that the minerals 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 associated with gold in Brazil, and also occasionally in the Urals and in the United States. In auriferous quartz ...
Aug 18, 2012· The presence of significant quartz makes the rock type quartzdiorite (>5% quartz) or tonalite (>20% quartz), and if orthoclase (potassium feldspar) is present at greater than ten percent the rock type grades into monzodiorite or granodiorite.
Oct 11, 2009· The short answer is that the conditions and the hydrothermal solutions that are needed for the deposition of gold are also right for the deposition of quartz. Of course, quartz can be deposited over a wide range of conditions, unlike gold which is why most gold deposits contain quartz also but most quartz deposits do not contain gold!
Unlike alluvial gold, which is found as very small flakes on river banks, goldbearing rocks have to be dug out of the ground. We want pure gold, but goldbearing rocks include lots of other materials such as quartz, calcite and the sulfides of other metals.
