Quick Answer Is Gold Found In Volcanic Rock Magazine

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.

Intrusive rock is formed when molten magma is pushed between layers of existing rock. Intrusive rock is typically very hard and erodes slowly. This allows the surrounding rock to be worn away by wind and water leaving only the harder rock in place. Heavy particles such as gold are likely to accumulate against the harder rock while the lighter materials are more easily moved away.

Pyrite Properties Amp Facts Britannica

Pyrite Properties Amp Facts Britannica

Pyrite a naturally occurring iron disulfide mineral. The name comes from the Greek word pyr fire because pyrite emits sparks when struck by metal. Pyrite is called fools gold to the novice its color is deceptively similar to that of a gold nugget.

Pyrite The Real Story Behind Fools Gold

Pyrite The Real Story Behind Fools Gold

Pyrite is widely distributed and forms under extremely varied conditions. For example it can be produced by magmatic molten rock segregation by hydrothermal solutions and as stalactitic growth. It occurs as an accessory mineral in igneous rocks in vein deposits with quartz and sulfide minerals and in sedimentary rocks such as shale coal and limestone.

Pyrite occurs in large deposits in contact metamorphic rocks. Deposits of copper-bearing pyrite are widely distributed and often of great size. They usually occur in or near the contact of eruptive rocks with schists or slates. Pyrite weathers rapidly to hydrated iron oxide goethite or limonite pseudomorphs of goethite after pyrite are common. This weathering produces a characteristic yellow-brown stain or coating such as on rusty quartz.

Historically pyrite was used commercially as a source of sulfur particularly for the production of sulfuric acid but today sulfur is largely collected as a by-product of petroleum processing. Because of the availability of much better sources of iron pyrite is not generally used as an iron ore.

Fools Gold is technically known as pyrite or iron sulfide FeS2 and is one of the most common sulfide minerals. Sulfide minerals are a group of inorganic compounds containing sulfur and one or more elements. Minerals are defined by their chemistry and crystalline structure. Minerals that have the same chemical composition but different crystal structures are called polymorphs.

Pyrite and marcasite for example are polymorphs because they are both iron sulfide but each has a distinct structure.Minerals can also have the same crystalline structure but different elemental compositions but its the crystal structure that determines the minerals physical characteristics.

In addition to pyrite common sulfides are chalcopyrite copper iron sulfide pentlandite nickel iron sulfide and galena lead sulfide. The sulfide class also includes the selenides the tellurides the arsenides the antimonides the bismuthinides and the sulfosalts. Manysulfidesare economically important as metal ores.

Pyrite is called Fools Gold because it resembles gold to the untrained eye. While pyrite has a brass-yellow color and metallic luster similar to gold pyrite is brittle and will break rather than bend as gold does. Gold leaves a yellow streak while pyrite8217s streak is brownish black. If you want to know more about how to tell real gold from Fools Gold watch this video produced by the University of Knottingham.

Pyrite is so named from the Greek word for fire pyr because it can create sparks for starting a fire when struck against metal or stone. This property made it useful for firearms at one time but this application is now obsolete. Pyrite was once a source of sulfur and sulfuric acid but today most sulfur is obtained as a byproduct of natural gas and crude oil processing.

Magma and Igneous Rocks. Igneous Rocks are formed by crystallization from a liquid or magma. They include two types Volcanic or extrusive igneous rocks form when the magma cools and crystallizes on the surface of the Earth Intrusive or plutonic igneous rocks wherein the magma crystallizes at depth in the Earth. Magma is a mixture of liquid rock crystals and gas.

The terms mineral and rock are often confused. They are frequently used together and the materials they describe are closely related. In general a mineral is a naturally occurring inorganic chemical element or a group of elements a compound. A mineral has a crystalline structure and a unique chemical composition. A rock is a mixture of particles or grains of one or more minerals.
