the gold formed

Gold is not formed, gold is an inert element and as such is almost always found in its elemental form. I assume you are referring to how gold deposits are formed on a geological time scale.

Well here something from wikipedia to get you started (this is to get you started you should do further reading as wikipedia is not a reliable source):

"Gold deposits are formed via a very wide variety of geological processes. Deposits are classified as primary, alluvial or placer deposits, or residual or laterite deposits. Often a deposit will contain a mixture of all three types of ore.

Plate tectonics is the underlying mechanism for generating gold deposits. The majority of primary gold deposits fall into two main categories: lode gold deposits or intrusion-related deposits.

Lode gold deposits are generally high-grade, thin, vein and fault hosted. They are comprised primarily of quartz veins also known as lodes or reefs, which contain either native gold or gold sulfides and tellurides. Lode gold deposits are usually hosted in basalt or in sediments known as turbidite, although when in faults, they may occupy intrusive igneous rocks such as granite.

Lode-gold deposits are intimately associated with orogeny and other plate collision events within geologic history. Most lode gold deposits sourced from metamorphic rocks because it is thought that the majority are formed by dehydration of basalt during metamorphism. The gold is transported up faults by hydrothermal waters and deposited when the water cools too much to retain gold in solution.

Intrusive related gold (Lang & Baker, 2001) is generally hosted in granites, porphyry or rarely dikes. Intrusive related gold usually also contains copper, and is often associated with tin and tungsten, and rarely molybdenum, antimony and uranium. Intrusive-related gold deposits rely on gold existing in the fluids associated with the magma (White, 2001), and the inevitable discharge of these hydrothermal fluids into the wall-rocks (Lowenstern, 2001). Skarn deposits are another manifestation of intrusive-related deposits.

Placer deposits are sourced from pre-existing gold deposits and are secondary deposits. Placer deposits are formed by alluvial processes within rivers, streams and on beaches. Placer gold deposits form via gravity, with the density of gold causing it to sink into trap sites within the river bed, or where water velocity drops, such as bends in rivers and behind boulders. Often placer deposits are found within sedimentary rocks and can be billions of years old, for instance the Witwatersrand deposits in South Africa. Sedimentary placer deposits are known as 'leads' or 'deep leads'.

Placer deposits are often worked by fossicking, and panning for gold is a popular pastime.

Laterite gold deposits are formed from pre-existing gold deposits (including some placer deposits) during prolonged weathering of the bedrock. Gold is deposited within iron oxides in the weathered rock or regolith, and may be further enriched by reworking by erosion. Some laterite deposits are formed by wind erosion of the bedrock leaving a residuum of native gold metal at surface.

'Pharaohs' first gold Naqboa in history where they discovered «120» mine in the Eastern Desert

The ancient Egyptians of the most brilliant of gold Naqboa, Fajlfoa 120 gold mine in the Eastern Desert extending to Sudan, and still impacts and gold jewelery attest to the ingenuity and skill of the ancient Egyptians in the exploration and the search for gold.
The Egyptians used gold at the time as a means for personal decoration only, not as a currency although the kings of strains from fourth to sixth used some gold coins, and despite technological development in which we live today did not reach a to any mine did not reach the hands of the Pharaohs until now.
The Pharaohs are the ones who reached the roads for gold operations, ranging from search to recovery, studies failed to demonstrate that they have imported any type or amount of gold, so they put their hands on each gold stock Egypt.
A study conducted since the eighties indicate that gold exists in three styles basic repeated in mines different, and these patterns involved in it are rocks Ultramafic, a rock high proportion of minerals containing elements Mafany, such as iron, magnesium, and because the metal ultramafic be the melting point high, these rocks crystallized from magma, first, before they lose a lot of elements of magnesium and iron.
And snatch the gold from the rock and then re-deposited in the form of veins, as well as the presence of gold in sediments surrounding valleys mines in the form of gestures, it was the first extraction of gold in the era of the ancient Egyptians, of these deposits is easy to operate and extraction, then turned then to the veins Originally found in mountains.
Numerous scientific studies which confirm that the quantities of waste resulting from the mines of the Pharaohs, calling for the re-evaluation of the remaining gold, indicating that it can extract gold from them now because they are still very rich Baltbr and this precious metal.
She also noted recent studies that there may be a lot of gold in the Eastern Desert, did not reach him Pharaohs, on some deep down mines pharaohs, which requires work studies to explore the feasibility of these new patterns on the rear, it represents one of the most buried treasures, especially since many geologists consider appropriate geological environment for gold in Central and South Eastern Desert is part of the circle of gold, which includes Sudan's north-western Saudi Arabia, including the Red Sea.

How gold formed??!

 

Out of gold:
Muslim scholars tried in the Middle Ages and others convert other elements into gold without success. Gold on the ground at may Otaha when the composition of the Earth by cosmic ash, which are for the explosion of supernovae. Gathered Ashes with the other components of the land and formed the earth, but formed the solar system as a whole. While creating the stars medium such as sun light elements such as helium and oxygen, carbon, nitrogen and others to iron (atomic weight 56), the element heavy like gold and atomic weight 197 - density is 3.19 g / cc - can not consist only in the intense heat, such as that produced by the explosion of a star. Then Tstadm atoms and particles to each other and coalesce part Bbeda thus composed of heavy elements such as gold. And all the heavy elements heavier than iron consists only supernovae explosion.

Scientists have been able in the modern era to convert other elements into gold for by bumped neutrons or other atoms Bonueh or in nuclear reactors, but way too expensive.

All information on gold

Gold is a precious metal yellow in color, and have known Gold since ancient times and was owning gold sign of affluence, has been known ancient Egyptians How are ways gold thin sheets, and during the Middle Ages grew fully aware of standing is called alchemy result attempts to make gold in ways artificial, at the present time some scientists succeeded to achieve the dreams of chemists veterans where it is now possible to extract gold from sea water.

There gold more than color, there Yellow Gold: It is pure gold, and produces shots of gold yellow and so by mixing gold with ratios of copper, silver and zinc in some cases, but must be controlled in these ratios tend color of pale whenever been reduced caliber.

 

* White Gold: Gold is mixed Balbladiom in order to acquire the color white and this was a substitute for platinum metal during the twenties of the last century and are white gold coating Balradeon and to restore the luster and sparkle and in the case of jewelry sets.

 And can determine the caliber of gold through a knowledge of the hallmarks which sealed and to show clarity and carat gold and shows as well as the place where the analysis.
 

- There are certain countries are the main countries for the production of gold and these countries are South Africa and the United States, Canada, Australia and China.

Gold
Everything in the world has a history including metals and therefore Gold has a history and should shed light on the history of this metal as a result of the importance of this metal.

Gold
There is a belief that the metal gold metal exists since ancient times, and use the pre-history.

* In Peru, they manufacture pots by gold and gold also mixed and since 1200 BC., And scientists also discovered artifacts and great gold jewelry dating back to the era of the Sumerians in 3000 BC.. 

 

 And there are important historical Gold Some of these stations is BC.

* 4000 BC. M: The first time I used gold in parts of Central and Eastern Europe.

* 3000 BC.: Egyptians are known in the art methods of gold and gold sheet metal, mixing gold with other metals to get different degrees of hardness and multiple colors. They also found a way casting gold, also known Sumerian civilization in Iraq using gold in the jewelery industry.

* 2500 BC. : Gold was buried in the tomb of Cheops first kings of the Pharaohs.

* 1352 BC.: The young king was buried Tutankhamun's tomb gilt, inside the gorgeous golden mask.

* 1350 BC. Babylon began to test the purity of gold by fire.

 

* 560 BC. : Making the first gold coin in Lydia in Asia Minor.

* 1100: famous Venice as the city of Bursa for its global gold in the middle of the trade routes to the east.

* 1900: America adopted the gold standard for its currency.

* 1922: When you open the tomb of King Tutankhamun was discovered shroud 2.444 a pound weight of gold, with hundreds of pieces of gold and gilded pots including mask referred to previously.

* 1927: proven medical study in France that gold is effective in the treatment of inflammatory rheumatic bones.

* 2000: Use astronomers in Hawaii Observatory giant mirrors giant gold-plated Observatory ever التلسكوبين, and in order to monitor more accurate images of the planet Neptune and Uranus.

 

 

Gold features chemical characteristics made ​​him a valuable metal as gold metal retractable recycling,

The gold metal is not affected to a large extent with water and air and oxygen, as it fits all climates natural, industrial and also does not react gold with oxygen, which is one of the most active elements and due to the lack interaction gold with oxygen, gold stainless Proof of this mask of Tutankhamun when extracted 1922 was a brilliant shining almost as it was since 1352 BC.

 Gold is one of the most reflective metal heat as pure gold reflects more than 99% of the
   incident radiation.

 Many uses for gold

* Potassium Saened gold and gold reels are used in jewelry and lipstick cans and lighters, and the liquid gold used in decorating ceramics and glass.

The gold is also used in the field of medicine where the gold solution used in the treatment of rheumatoid arthritis and bone infections, as well as in dentistry since 3000.

* And gold is used in electronics and through links gold-plated in the computer, and telecommunications equipment, and household appliances, such as televisions, washing machines, and films of high or thick circuits Minor, which requires the development of toothpaste went like ink on ceramic base

And also gold is used in the field of space and in the coating of aircraft engines, missiles gold helps to reflect heat and also gold-plated sheets used as a shield against radiation in satellites and space allowances men.

The South Africa and the United States, Canada, Australia, China and the Philippines are the main producing countries in the world and went different ways to get the gold depending on the type of sediment are obtained two gold in two steps that are essential:

1 - get a raw
2 - separation of raw gold

 

Gold and Industry

Gold is used in the electrical, electronic and particularly in printed circuit conductors and in particular in the sub-links made ​​of silicon coated and Blamkan used to cover the windows, helping to alleviate and reduce infrared At the same time let enough light The wire gold bullion are used in measurement equipment and measurements heat.

Gold mining methods
Activity gold mining economic activity important for many countries, and use as a source of wealth for many people on a bitter history and there are several different ways currently being used to extract gold and minerals, and the MRA for years may Omstkhaddma different types of mining equipment for gold, depending on the location and type of gold mine for that style mining user of these factors varies, and there is more than one way to gold mining, including mining alluvial deposits and hard rock mining.

 

And more roads mining widespread among ordinary people is rock mining Ahlgreninh considered months mining methods are widespread among young gold miners, called the free float where floats gold within sediments and rocks crushed, and Henk types several of rock mining Algarnih, and Okthera types used is extracted goldpanning, when it fills the pot and sandy sediments that may contain gold and immersed in water for floating, and because of the density of gold, gold sink to the bottom, allowing the remaining sediment laundering and stay gold

 

And there Okhrmen type granite mining methods Lainé, by creating a channel or the Listed Fund, through which water containing gold deposits where flowing through that channel, where gold is deposited in the bottom of the Fund

 

Another way of granite mining methods Winnie but less use where it is to bring a small device floats Li surface water and sediment is used to suction from the bottom,

 

This is another way to gold mining, rock mining and used m this method to extract the gold that was found inside the rock, instead of sediment milled A, gravel to extract her kind of gold, is the work of slot inside rocks or in the ground and put mine where, is separating the gold fromrocks using mining tools and uses this method in South Africa dramatically, and in most cases is to find gold and next to him and copper deposits

 

For information, there is the deepest mine in the world in South Africa and a depth of up to about 3900 under the earth's surface
