Why is gold found in some locations but not in others?

During their ascent the conditions change (be it temperature or pH, etc.) and the water are not capable of carrying gold with them anymore. This results in the deposition of gold in that specific region. So in here you have rain water, entering the Earth in a large area and getting hotter as they descend down.

Why is there gold in some places and not others?

Gold is usually found in rivers and streams because water is the most efficient/fastest way of moving rocks and minerals. Because gold is typically deposited by moving water, which carries many other different types of rock, it's not always found near a particular type of rock.

What determines where gold is found?

The erosion process of water over time reveals the places in which large gold deposits can be found. Streams that cut through the rocks carry the smaller elements of gold down with them.

Where is gold mostly found and why?

Gold is primarily found as the pure, native metal. Sylvanite and calaverite are gold-bearing minerals. Gold is usually found embedded in quartz veins, or placer stream gravel. It is mined in South Africa, the USA (Nevada, Alaska), Russia, Australia and Canada.

Can gold be found everywhere?

Gold is everywhere on Earth, it's just not commonly found in significant concentrations. The Earth's crust contains approximately 0.004 grams of gold per ton, and there is even a lot of gold in saltwater - but concentrating the trace amounts just doesn't make economical sense.

How To Find Gold: Ten Natural Geologic Indicator Hacks

How do you know where gold is in the ground?

Lighter Colored Rocks: If you notice out-of-place colors in a group of rock formations, it can be a gold indicator. Acidic mineral solutions in gold areas can bleach the rocks to a lighter color. Presence of Quartz: Quartz is a common indicator that gold MAY be nearby.

Where is the easiest place to find gold?

Where is gold most often found?

About 244,000 metric tons of gold has been discovered to date (187,000 metric tons historically produced plus current underground reserves of 57,000 metric tons). Most of that gold has come from just three countries: China, Australia, and South Africa. The United States ranked fourth in gold production in 2016.

How deep is gold in the ground?

Other gold mines use underground mining, where the ore is extracted through tunnels or shafts. South Africa has the world's deepest hard rock gold mine up to 3,900 metres (12,800 ft) underground. At such depths, the heat is unbearable for humans, and air conditioning is required for the safety of the workers.

What rocks is gold found in?

Gold is most often found in quartz rock. When quartz is found in gold bearings areas, it is possible that gold will be found as well. Quartz may be found as small stones in river beds or in large seams in hillsides.

What kind of soil is gold found in?

Soils Associated with Gold Deposits. By far, the best-known type of soil which may indicate the presence of gold is known as “black sand.” Black sands are certainly not proof of the existence of nearby gold, only that the soil has a lot of minerals and heavy metals, one of which is gold.

How do you tell if a rock has gold in it?

One of the easiest and most telling tests for gold that you can perform on your rock is for hardness. This test is an application of Mohs hardness scale, which compares the hardness of different minerals by scratching them against one another.

Can gold be found in any river?

Gold is a natural metal that can be found almost everywhere—streams, rivers, oceans, rocks, and the Earth's crust.

Does gold grow in the ground?

Now a study by Australia's Cooperative Research Centre for Mineral Exploration has found that microbes in the soil suck together microscopic traces of gold in the ground, causing them to lump together and eventually form nuggets.

What happens if you find gold?

If you discover gold or other minerals or gemstones on land not covered by a mining tenement, and the ground is Crown land (under the Mining Act 1978), then you are free to keep what you have found (as long as you hold a Miner's Right).

Can all metal detectors find gold?

The answer is YES, they all do. Some do it better than others. Some detectors like the Minelab Gold Monster or GPZ 7000 are specifically designed to find small gold pieces (which most naturally occurring gold is). When it comes to finding gold rings, just about any metal detector will work.

What plants contain gold?

The flowering perennial plant alfafa, for example, has been cultivated by scientists to contain pure gold in its plant tissue. Now researchers from the Sun Yat-sen University in China have identified and investigated the characteristics of gold nanoparticles in two plant species growing in their natural environments.

Does black sand indicate gold?

Black sands (mostly iron) can be and usually is an indicator of gold, but not always. Rule of thumb is you will generally find black sand with gold, but not always gold with black sand. However if you are finding gold and getting black sands with it, it would be worthwhile to try some and see what happens.

How much gold is still undiscovered?

According to the US Geological Survey, the underground gold reserves are currently estimated at about 50,000 tons.

Where is the purest gold found?

According to financial marketplace Policybazaar.ae, the Emirate of Dubai (an independent city-state in the United Arab Emirates) is the best place in the world to buy pure gold—or the highest purity available on the market today, given what was mentioned above about gold in entirely pure form.

Why is there no gold in Florida?

Unfortunately, limestone deposits in Florida are not gold-bearing. The limestone itself has a variety of different commercial uses, but for gold prospectors it is of little interest. There are no known gold deposits in Florida.

How does gold naturally occur?

Gold may occur as deposits called lodes, or veins, in fractured rock. It may also be dispersed within Earth's crust. Most lode deposits form when heated fluids circulate through gold-bearing rocks, picking up gold and concentrating it in new locations in the crust.

What state has the most gold in the ground?

1. Nevada. Currently the top gold mining state of the US, Nevada is home to three of the world's top 10 gold mines and seven of the top 10 US sites. Nevada's Goldstrike is the top gold mine in the US, followed by the Cortez and Carlin Gold Mines, with all three located in north-central Nevada.
