In epithermal gold deposits, it is quite common for sizable gold veins to run through quartz rock, and these specimens can be located using a […]
Gold encased in quartz rock, also known as gold specimens, are highly sought after by collectors and prospectors. They can be hard to find, but using the proper equipment and tactics, it is possible to find beautiful specimens.
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!

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.
Most prospectors, when they think of hard rock gold deposits, think of quartz containing particles of gold. While gold deposits can be things besides quartz veins, gold is certainly found in the quartz of veins cutting through various types of rocks. Gold in quartz veins occurs as particles and scales scattered through the quartz, often filling ...
Quartz-gold deposits are formed from high temperature water (hydrothermal) that has passed through rocks at depth. No not all Quartz veins contain gold and not all gold is found in Quartz.
Gold is found widely diffused in nature even though it is one of the scarcer metals. Very commonly, gold occurs as the native metal encased within quartz. Sometimes the gold is in a finely divided state, sometimes in particles of considerable size, as nuggets, grains, scales, plates, threads and wires in quartz rock.
Layers, or reefs, of quartz rock containing gold are found deep in the earth. Gold in Ireland (2003). - Minerals Ireland 0.3g/t Au, with some pyritic rocks containing up to 0.75g/t. Au. Much of the gold appears to ... Quartz vein containing visible gold at Cregganbaun. Drill core from ...

Veins and reefs of gold-bearing quartz can occur in many types of rock, for example around granites, in volcanic rocks or in regions of black slate, but in most cases these host rocks are not the ...
Dec 17, 2009· Answer Quartz does not contain gold. Gold is found in quartz, but is not a constituent of the mineral, quartz. Although gold can chemically, be found in rare metallic sulphides, when found in ...
The answer is "maybe." First things first: gold is found almost everywhere, including dissolved in seawater. If you're in the USA, the geological survey lists locations where significant amounts have been recorded. When it's directly associated ...
Much of the gold mined is actually from gold ore rather then actual Gold specimens. The ore is often brown, iron-stained rock or massive white Quartz, and usually contains only minute traces of gold. To extract the gold, the ore is crushed, then the gold is separated from the ore by various methods.

A 95 kg quartz rock containing almost 70kg of gold has been dug up in Western Australia — as well as the 70kg of gold, worth almost $3 million, another 46kg of gold was found in a second stone ...
Aug 18, 2012· The presence of significant quartz makes the rock type quartz-diorite (>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.
Gold And Quartz Specimens. This page is dedicated to the gold that’s still attached to quartz, or a host rock. This type of gold is highly desired in the mineral collecting community. Gold/Quartz specimens are in a completely different league of their own. Remember the specific gravity of quartz is 2.65 times heavier than water, whereas pure ...
Identifying gold bearing ore just by visual inspection can be very difficult, or even impossible, depending on the concentration of the gold within the rock. Many ores that contain gold contain other metallic metals in them also, so there are likely to be a lot of shiny minerals mixed into the rock which may or …

Quartz is a major component of many types of rock. Quartz is abundant in certain igneous rocks. It forms the clear to grey or even white lumpy blobs in granite and comprise most of silicate-rich or felsic igneous rocks. It is absent or rare in more primitive basic or silica-poor igneous rocks such as basalt.
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 ...
Unlike alluvial gold, which is found as very small flakes on river banks, gold-bearing rocks have to be dug out of the ground. We want pure gold, but gold-bearing rocks include lots of other materials such as quartz, calcite and the sulfides of other metals.
For example, a rock that is entirely made of albite, NaAlSi 3 O 8, a feldspar, has 0% quartz content, but contains 77.3% silica (weight percent).. It was once customary to express the chemical composition of a mineral as an oxide formula (mostly because the structural relationships between the elements involved were not precisely known), and it is still useful if one reflects the silica content.
