What is Gold?

Gold is a transition metal with the symbol Au derived from the Latin word for Gold, Aurum and the atomic number 79 on the periodic table. Gold is a chemical element, a bright yellow metal with a lustrous shine and is one of the most chemically inactive elements, which is why it is highly resistant to corrosion and oxidation. This precious metal is very dense, a good conductor of electricity, and very ductile, meaning it can be bent or rolled into different forms without cracking.

Gold has been used for a number of purposes in the course of human history. Due to its scarcity and special characteristics, it has been associated with prestige and wealth, and has been used in minting of coins, gold ornaments and gold bars. These characteristics of gold make it ideal for use in electronics and dentistry due to its physical properties. It is used in spacecraft and high tech applications due to its reflective characteristics.

Where Does Gold Originate?

The origin of gold can be traced to farthest corners in the universe, farther than our solar system. Understanding the source of gold requires investigating astronomical phenomena that occur and geological conditions on Earth.

Astronomical Origins of Gold

The beginning of gold takes place in the stars. Heavy elements, such as gold, are synthesized through nucleosynthesis in the violent conditions of supernovae and neutron star mergers.

Supernova nucleosynthesis occurs when a massive star collapses at the end of its life cycle, causing extremely high temperatures and pressures that can allow for heavier elements to be created by fusing with lighter ones. These mighty explosions disperse atoms of gold all over space.Gravity waves and enormous energy result from colliding neutron stars which produce heavy elements like gold. Although they occur infrequently, these events are immensely powerful and contribute to the prevalence of gold in this universe.

Geological Conditions for Gold Deposition

Gold is deposited through certain geological conditions on Earth，often as a result of tectonics and hydrothermal activities. Different types of minerals, including gold, are brought to the crust by molten rock rising from the mantle. When this magma cools down and solidifies, it can trap gold in quartz veins and other rock formations.

Processes related to hot solutions are very important in gold deposition. Gold together with other kinds of mineral is carried by these hot fluid-rich solutions as it reacts with surrounding rocks cooling along fractures and cracks within the Earth’s crust. Such processes usually happen in areas that have intense volcanic activity because such areas provide the best conditions for forming minerals that are rich in nature. Over millions years, these geological conditions have played an important role in concentrating economically viable gold deposits such as those found in South Africa’s Witwatersrand Basin as well as placer deposits in stream beds and alluvial plains.

How is Gold Formed?

To comprehend how gold is formed, one needs to consider both cosmic and geological factors that have influenced the distribution and availability of the metal.

Astrophysical Processes

Supernova

Gold is primarily formed in the explosive aftermath of a supernova, one of the most powerful explosions in the universe. Massive stars run out of nuclear fuel and collapse before exploding. These explosions generate such high temperatures and pressures as to promote atomic reactions that create heavy elements such as gold. The explosion’s energy disperses these just-formed gold atoms throughout space supplying surrounding interstellar medium with valuable metals. Ultimately, they are among the dispersed gold atoms which are later assimilated into cosmic dust that constitute new stars, planets and other celestial bodies.

Neutron Star Collisions

Another significant astrophysical process that contributes to the formation of gold is the collision of neutron stars. When two neutron stars, remnants from supernovae that have undergone gravitational collapse, come together spinning around each other until colliding, they produce a huge amount of energy. This violent collision creates conditions even more extreme than those in a supernova, leading to rapid capture of neutrons by atomic nuclei—a process known as r-process nucleosynthesis. This process produces an abundance of heavy elements, including gold. The ejected gold from such collisions adds to what already existed in this metal within universe.

Cosmic Dust

Cosmic dust, which is a fine powder that originates from stars and other celestial objects, is also involved in the creation of gold. In such events as supernovas and neutron star collisions, a lot of energy is produced and lighter elements combine to form heavier elements like gold. These newly formed gold atoms are then expelled out into space and become part of the cosmic dust that is present in the universe today. This gold-bearing dust gradually gathers and becomes the material that creates new stars and planetary systems.

Earth's Geologic Processes

Hydrothermal Activity

The hydrothermal process is one of the most significant in the formation of gold deposits on our planet. It entails the circulation of hot, mineralized fluids in the Earth’s crust in cracks and fissures. These fluids are derived from magma sources in the Earth’s mantle and transport dissolved gold together with other species. Hydrothermal fluids rise through the porous rocks and when they come in contact with the surface, they cool and deposit the gold from the solution in the form of solid minerals. This is especially common in areas with high volcanic activity because the heat and pressure here are perfect for hydrothermal systems. The end product is the formation of gold bearing quartz veins which can be exploited for precious metal content. Some of the richest gold deposits in the world such as those in the United States and South Africa are associated with hydrothermal activity.

Placer Deposits

Placer deposits are created when gold is eroded from its parent material and carried by water to a new location where it settles in river channels, stream gravels, or coastal sands. In the long run, the denser gold particles sink and accumulate at these places due to their density, leaving behind other materials such as sand and gravel. These deposits are relatively easier to exploit than hard rock sources, since gold can be easily recovered using methods such as panning, sluicing and dredging. The placer deposits have been one of the most important sources of gold and have led to the formation of gold rushes and large scale production of gold in the world.

Meteorite Delivery

The Earth’s surface has been significantly affected by meteorite impacts in bringing gold to it. When the Earth was forming, there was heavy bombardment of the planet by meteors and asteroids. Many of these were made up of heavy elements such as gold. Their impact on the earth resulted to deposition of their metallic content into the crust.

This process helped distribute gold across the earth’s surface, especially in areas with high rates of impact cratering. Nevertheless, gold deposits created through meteoritic delivery are relatively rare compared to those formed through geological processes alone. Gold brought to earth millions ago by impacts have become localized accumulations that have subsequently moved and transformed by later geologic events. Despite playing a role in enriching global stores of gold, meteorite delivery is not the main way this precious metal forms on our planet.

Which is the Easiest Way to Get Gold?

Out of all the processes that take place on Earth and in space, the geologic processes are the most convenient and feasible for extracting gold on Earth. Supernovae and neutron star collisions produce gold in space but this gold is spread across the universe and cannot be obtained easily. Meteorite delivery while it has added to the gold reserves of the earth, does not leave the gold in a single concentrated area. While on Earth, geological processes such as hydrothermalism concentrate gold into economically viable forms such as quartz veins and placers. These formations are easier to extract and purify, and therefore are the main source of gold for human consumption.
