At different times in the earth’s history, hot fluids circulated through gold-bearing rocks and because of the weight and chemical properties of the gold, the gold may have been carried off to form a vein or a lode. In other instances, gold flakes and nuggets broke off and were carried away by water’s currents.
During the formation of Earth, molten iron sank to its centre to make the core. This took with it the vast majority of the planet's precious metals -- such as gold and platinum. In fact, there are enough precious metals in the core to cover the entire surface of Earth with a four-metre thick layer.
On Earth, gold finally reached us some 200 million years after the formation of the planet when meteorites packed with gold and other metals bombarded its surface. During the formation of Earth, molten iron sank to its centre to make the core.

Gold-laden water heated by magma-molten rock-in Earth's shallow crust forms a variety of lode gold deposits. Hydrothermal-hot water-fluids rich in sulfur form gold ores in rocks of active volcanoes. The deposits of Summitville, Colorado, are an example.
Then once a planet like Earth is formed, somehow geologic forces take over and process the gold into enriched forms until we find it. Another possibility is that other elements that are formed from supernova and are radioactive and have a higher atomic number than gold decay into gold.

"Beneath volcanoes, most of the gold is not precipitated in faults that are active during earthquakes," Wilkinson said. "It's a very different mechanism." Understanding how gold forms helps companies prospect for new mines.
Gold is an element and is formed in the core of large stars, especially during a nova. On Earth, veins of gold are formed by separation from liquid rock after gravity agglomerates the molecules. It will form long chains within spaces in minerals because of its resistance to combining with lighter elements.
Deep in the Earth's crust, silver is one of the important metals that can be found, along with gold, copper, lead and zinc. It is formed by forming compounds with sulfur. Due to hot temperature, salty water called brine dissolves, collects …
Oct 08, 2015· Did you know that gold is extraterrestrial? Instead of arising from our planet’s rocky crust, it was actually cooked up in space and is present on Earth because of cataclysmic …
Gold was among the first metals to be mined because it commonly occurs in its native form, that is, not combined with other elements, because it is beautiful and imperishable, and because exquisite objects can be made from it.
But it doesn't explain how the gold atoms actually got to earth and formed into the gold deposits that we see throughout the world. The newly formed gold atoms were blasted in all directions when two neutron stars collided and exploded.
The idea that gold came from outer space sounds like science fiction, but it has become well-established - it's pretty much received opinion in the field of earth sciences.
Gold forms in the underground vents of volcanoes. The super hot gases rising from deep beneath the Earth flow through natural 'pipes' carrying elements within them. These mineral elements condense ...
Specifically, in the case of the Earth, it would have taken about 30 million years. However, the majority of the gas and dust would have collected at the centre of this spinning disc to form …

The researchers determined the tungsten isotopic composition of these rocks. Tungsten (W) is a very rare element (one gram of rock contains only about one ten-millionth of a gram of tungsten) and, like gold and other precious elements, it should have entered the core when it formed.

Gold atoms are not formed in the earth, but existed before the earth was formed. I have read somewhere that gold atoms were formed in stars or supernovae or so, and that remnants of those explosions became the raw material for …
Gold deposits have formed at many different times during Earth’s history. For example, those in Western Australia are believed to have formed about 2400 million years ago, during a period of intense metamorphism and intrusion of igneous rocks.
The gold is basically dust in the wind, atomized, until it moves into a cloud of material that can coalesce, through the force of gravity, into a solar system of planets with a star at the center. Early in Earth’s history, asteroids containing gold …
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. To make money - or at least have a decent chance at it - …
We value gold for many reasons: its beauty, its usefulness as jewelry, and its rarity. Gold is rare on Earth in part because it's also rare in the universe. Unlike elements like carbon or iron, it cannot be created within a star.
The average concentration of gold in Earth’s crust is estimated to be between 0.0011 ppm and 0.0031 ppm. Now we can calculate the volume of the portion of the crust which can potentially be mined. Now we can calculate the volume of the portion of the crust which can potentially be mined.
Copper appears most frequently in deposits in which lead, silver, gold and zinc are also present. Porphyry copper deposits contain the most significant finds of copper; porphyry deposits began as large concentrations of molten rock that slowly cooled, crystallizing inside Earth's crust.
Gold (Au) is a precious metal and has been mined since the ancient Egyptian times; whilst smelting and fusing of gold-rich ores has been reported since 3600 BC. Gold occurs in many different rock types and geological environments and economic deposits are mainly of two types: lode deposits and placer deposits.
The effort to understand the geology of gold was perhaps man's first serious effort at understanding the earth's rocks and minerals. Gold is actually a relatively scarce element on the crust of the earth, but it occurs in trace quantities spread throughout many different kinds of rocks and in many different geological environments.
Gold is an element and is formed in the core of large stars, especially during a nova.On Earth, veins of gold are formed by separation from liquid. Live Chat Where does all the gold come from?
Over the billions of years, it took to form the earth, that gold along with most other metals given to us by the sun, has sunk to the magma core of our planet. There is enough gold in the center of the earth to cover the surface with a 1.5-foot-thick layer.
Apr 15, 2011· Best Answer: Gold, like other elements such as iron, forms when stars explode (nova or supernova). We find it here because Earth and the Solar System coalesced from the debris of older stars. Gold is found underground in veins or nuggets, on the surface in alluvial deposits, and in the oceans.
