Vein quartz is often white and frequently contains gold. This quartz is little used in gems, except cabs with milky quartz and yellow gold specks. ... Quartzite A rock made up of tightly packed quartz grains, formed at high temperature and pressure, due to metamorphism.
· Gold has been historically mined in certain areas of the west coast and Rocky Mountains, Australia, South America, and central Europe. Check the natural cracks and lines of the quartz rock. Gold often occurs along the natural linear structures of quartz rock.
· 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 .
· A lot of veins I see are right up against a huge rock or fault, or between two visible faults on either side of the vein, but sometimes there's just one rock face. Usually the quartz is right up against the rock. I always assumed that was the contact zone and that the gold would be trapped in that quartz against the rock.
Gold Bearing Quartz is found in underground hard rock mines in the same areas where gold nuggets are found. In Alaska, it was first discovered in 1880 in the town of Juneau. Regions of Canada, California, the Western United States and Australia are also well known for Gold Bearing Quartz.
Gold And Quartz Specimens. This page is dedied 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.
Gold in Quartz February 2016 (Vol. 85, No. 06) ICMJ's. 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 stered through the quartz, often filling cracks and openings in the vein price
Answer (1 of 12): 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 loions where significant amounts have been recorded. When it's directly associated with quartz, it often appears in...
Gold is very dense and never rusts, as the surrounding rock is weathered, tuned to clay and sand, it liberates gold. The gold tends to stick around due to its density, so it can accumulate in highly weathered soils above gold bearing quartz veins. The soils end up with a higher concentration than the original quartz .

What is Quartzite? Quartzite is a nonfoliated metamorphic rock composed almost entirely of forms when a quartzrich sandstone is altered by the heat, pressure, and chemical activity of metamorphism.. Metamorphism recrystallizes the sand grains and the silica cement that binds them together. The result is a network of interlocking quartz grains of incredible strength.
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.
· Rutilated quartz's color is largely determined by its inclusions. While the quartz itself is colorless, the color of its inclusions can vary. Goldcolored inclusions are most common, but the inclusions can also be black, dark redorange, or silver, just to name a few. High amounts of iron oxide can give rutilated quartz red or gold needles.
· Although gold was discovered in just about any type of rock that is found on Earth prospecting in quartz conglomerates is a pretty good bet. In the eastern United States quartz pebble conglomerates are commonly found in the Queenstown Delta as exemplified by the Schwangunk Ridge of New York and New have been reports of sparse gold deposits associated with this .

Quartz's clarity earns it a raw price of around /carat and a gem price of 17/carat. Amethyst, or purple quartz, is the most valuable variety (can reach 15/carat), but pink, rose, and smokey quartz is also valuable. Clearer, more vibrant, and unbroken specimens are the most valuable quartz. The prices per carat do vary widely ...

Rocks are sometimes cut by quartz veins at random orientations, with or without crystals. In other cases there is an obvious pattern in the orientations of the veins: for example, when a igneous rock shrinks during cooling, the cracks may develop into a regular system of fissures that might be filled with quartz from percolating hot brines.
