Gold is found in nearly every continent of the world. Primary gold is found in rock formations, secondary gold is found in waterways. There are many places were finding gold ismon occurrence. There are two categories for gold found in nature.
100 of gold found naturally is isotope Au 197. 28 other isotopes can be produced artificially and are all radioactive. Gold along with silver and copper, form a column in the periodic table. They are found naturally and were the first three elements known to man. They were all used as primitive money well before the first gold coins which appeared in Egypt around 3400 BC. Most gold is ancient
Gold Au, chemical element, a dense lustrous yellow precious metal of Group 11 Ib, Period 6, of the periodic table.Gold has several qualities that have made it exceptionally valuable throughout history. It is attractive in colour and brightness, durable to the point of virtual indestructibility, highly malleable, and usually found in nature inparatively pure form.
In the U.S., the most famous Gold producing states are California, Nevada, South Dakota, and Alaska. California, home to the Gold rush in the Sierra Nevada Mountains, abounds in historical mining towns and many scattered occurrences. Many are long forgotten, but here is a list where some very fine specimense from.
Gold is primarily found as the pure, native metal. Sylvanite and calaverite are gold bearing minerals. Gold is usually found embedded in quartz veins, or placer stream gravel. It is mined in South Africa, the USA Nevada, Alaska, Russia, Australia and Canada.

When gold is found in rocks it is almost always in a pure state. Large pieces of gold are called nuggets and tiny pieces are known as gold dust. Themon unit of measurement for gold is the troy ounce. One troy ounce of gold weighs 31.1 grams.
Gold is most often found in quartz rock. When quartz is found in gold bearings areas, it is possible that gold will be found as well. Quartz may be found as small stones in

Gold is a chemical element with the symbol Au from Latin: aurum and atomic number 79, making it one of the higher atomic number elements that occur naturally. In a pure form, it is a bright, slightly reddish yellow, dense, soft, malleable, and ductile metal. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions. Gold often occurs in free elemental native form, as nuggets or grains, in rocks, in veins, and in alluvial deposits
