Native metal

Native silver occurs as elongated dendritic coatings or irregular masses. It may also occur as cubic, octahedral, or dodecahedral crystals. It may occur alloyed with gold as electrum often occurs with silver sulfide and sulfosalt minerals. Various amalgams of silver and mercury or other metals and mercury do occur rarely as minerals in nature. An example is the mineral eugenite (Ag 11 Hg 2 ...

How Is Gold Formed? Origins and Process

 · Gold sank to the Earth''s core during the planet''s formation. It''s only accessible today because of asteroid bombardment. Theoretically, it''s possible to form gold by the nuclear processes of fusion, fission, and radioactive decay. It''s easiest for scientists to transmute gold by bombarding the heavier element mercury and producing gold via decay.

GOLD (In Its Natural State)

 · How does gold end up as nuggets, flakes, grain, dust, and flour? When gold is spewed from the inside of the earth to its surface, it is molten. Veins of gold are formed by the gold flowing down a mountain as it cools. Thus, natural gold is formed. Quartz is often found embedded in these veins and still can be seen in some of the natural gold.

Where Is Gold Found On Earth?

 · Secondary gold actually comes from primary gold and is often found in streams, rivers, waterways, and creek beds. This secondary gold, called placer gold, is a result of millions of years of erosion of primary gold.

In What Rock Formations Can Gold Be Found? | Sciencing

 · Alluvium is a deposit of eroded materials and sediment that is gathered into one area. As gold and other materials are eroded, the small pieces are pushed by water and other forces into creek and river beds and other depressions. Because gold is heavier than most other naturally occurring materials, it settles at the bottom of these deposits.
