Aug 22, 2014· Gold Geology and the Natural Indicators that can help you find gold. Not all gold deposits out there have been found and mined. There are still places that contain gold that have never been worked, despite the fact that miners have been searching for gold for hundreds of years now.
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 ...
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 ...
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.
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.
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 ...

Quartz is also the most varied of all minerals, occurring in all different forms, habits, and colors. There are more variety names given to Quartz .
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 .

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.
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.
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.

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.
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.
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 ...
