How are gold and silver formed?



Gold is formed with molten rock, which is called magma then being intruded into solid rock. Then the magma cools and it becomes solid water and other substances in high pressure separate out from the magma. This hight pressure that forces out the water turns the water into a hot water and steam that forces open the fissures in the rocks that are around the solid rock.

Through these solid rocks there is a hydrothermal solution that travels out. After the hydrothermal solution that is traveling out cools down it the deposition of material occurs. One thing that you need to know about gold is that it has a very low melting temperature, this low melting temperature is sometimes carried by these hydrothermal solutions. The best place to look for gold is usually in the quartz veins located near the intrusion of a magma body. One famous place of this quartz veins is in the Sierra Nevada which is located in California. If these quartz veins were to erode gold would be found in the streams and rivers in the foothills of the Sierra Nevada.

Some other stuff that are also being used made by silver are watches, clocks, cameras, calculators, and hearing aids that are battery driven, and other small button shaped batteries that are used in consumer products are also made of silver-oxide. One unique thing about silver is that it has an optical reflectivity that allows it to be used both in mirrors and in heat reflective coatings on glass, cellophane or metals.

Silver is used in photography to produce wide variety of formats and sizes, tailored to four user categories, consumer, radiography, graphic arts and others.
