Pyrite is usually found associated with other sulfides or oxides in quartz veins, sedimentary rock, and metamorphic rock, as well as in coal beds and as a replacement mineral in fossils, but has also been identified in the sclerites of scaly-foot gastropods. Despite being nicknamed fool's gold, pyrite is sometimes found in association with small quantities of gold.
Answer (1 of 2): Pyrite is an Iron sulphide mineral with chemical composition of FeS2. When the mineral is fresh it appears as gold nuggets and hence called as "Fools gold". After exposed to atmosphere, it starts weathering and becomes dark brown, leaving dark brown stains (iron stains) on the ho...
Pyrite, also known as 'fool's gold' for its metallic, golden appearance, is not an igneous, sedimentary, or metamorphic rock. What is called fool's gold? Fool's Gold can be one of three minerals. The most common mineral mistaken for gold is pyrite. Chalcopyrite may also appear gold-like, and weathered mica can mimic gold as well.

quartz rock. Is fools gold magnetic? Pyrite and gold both have a brilliant metallic luster but are different tones of yellow. Even though gold is a metal, it is a non-ferrous metal (i.e. has low iron content), so it will not stick to a magnet; pyrite, however, has a high iron content and …

Fool's gold fossils, such as ammonites, are very popular with collectors and are often found in sedimentary rocks. Iron pyrite is a fairly common mineral, and is mined or extracted globally for its many industrial uses, such as extraction of the sulphur for sulphur dioxide or …
-The biggest gold nugget ever found was dug up in Australia in 1869 and weighed 78 kg.-Although a lot of gold has been dug up, 80% of the world's gold is still buried underground. Pyrite is a different mineral that can be found in other rocks. It looks a lot like gold and so has been given the nickname 'fools gold'.
Igneous Rocks - Set of 6 igneous rock specimens (basalt, rhyolite, porphyry, granite, scoria, obsidian) for you to identify. For a boxed collection of 15 igneous specimens see - Igneous Rock Collection (1309-000). Find more igneous rock specimens on our Igneous Rock Specimens page.
Learn about Sedimentary, Igneous, and Metamorphic rocks. The kit includes real specimens from each rock type so you can examine them first hand. Rocks included are: Sedimentary Rocks (Sandstone, Conglomerate, Limestone), Igneous Rocks (Basalt, Granite, Pumice), Metamorphic Rocks (Marble, Schist, Quartzite).
"Fool's 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…
During the period of Gold Fever, Coloradoite was often taken for gold. It is usually called fools gold rock. And it does contain a certain amount of precious metal. However, the danger of this crystal is hidden in its ability to emit toxic vapor. It can cause ulcers, tumors, and scarring.
Pyrite, often called "Fools Gold", has a silvery-yellow to golden metallic colour.It is very common and may occur in large crystals. It has been used by ancient civilisations as jewellery, but is hardly used nowadays. Pyrite is sometimes incorrectly known as Marcasite in the gemstone trade. Marcasite is mineral that is a polymorph of Pyrite, and can be fragile and unstable, and is not fit for ...
Minerals are naturally-occurring elements or compounds that are the constituents of igneous, metamorphic, and sedimentary rock. In unusual circumstances, minerals may grow into typical crystal forms that make them desirable to collectors. ... This mineral is commonly known as "fool's gold" because it has been mistaken so often for gold ...
Biotite is a name used for a large group of black mica minerals that are commonly found in igneous and metamorphic rocks. These include annite, phlogopite, siderophyllite, fluorophlogopite, fluorannite, eastonite, and many others. These micas vary in chemical composition but are all sheet silicate minerals with very similar physical properties.
What Is Fool's Gold? "Fool's gold" is a common nickname for pyrite.Pyrite received that nickname because it is worth virtually nothing, but has an appearance that "fools" people into believing that it is gold.With a little practice, there are many easy tests that anyone can use to quickly tell the difference between pyrite and gold.
Porphyry Deposit: A low-grade, disseminated metallic deposit that is hosted by igneous rocks. Pyrite: Fools gold, an iron sulfide mineral. Rift: A major break in the earth's crust, which often releases metal-rich hydrothermal fluids and/or molten rock. Ruby Silver: A common term for 2 red silver sulfide minerals, proustite and pyrargyrite.
Fools gold is Pyrite, an igneous rock, that can only told different from gold by the color of its streak. Study guides.

Answer: Anything. Most 'hard rock' (non placer) gold deposits are the result of hydrothermal (hot water) solutions carrying gold (and other elements) into the area where conditions are right for gold to drop out of solution. The most important factor there isn't the composition of the rocks, bu...
Pyrite is know as Fools Gold. Pyrite bears another interesting nickname: fool's gold. In fact, because of its color, weight and metallic shine, pyrite is often mistaken for gold. In the gold rush era, when prospectors were hoping to strike it rich, many of them were disappointed to learn that the discovery they thought was gold, was, in ...
During the gold rush of the 1800s, pyrite earned the moniker "fools gold" because its superficial resemblance to gold ended up confusing many novice gold miners. ... These compounds were formed after igneous rocks are pressurized, heated, and subsequently changed over millions of …
