A brass-yellow mineral with a bright metallic lustre that usually occurs in veins of all classes of rocks; often associated with gold mining and referred to as fool's gold.

Brass-yellow mineral with a metallic lustre composed of iron and sulfur. It is a widely found ore of sulfur and occasionally iron.

the iron-sulfide mineral, often called "fools gold," that is found in earthen and rock layers near coal seams. Pyrite is the usual source of the sulfur that binds with hydrogen and oxygen in rain water to form the sulfuric acid component of AMD.

a metallic, yellow mineral composed of iron sulphide: FeS2. Pyrite is the most abundant sulphide mineral.

Gold coloured mineral composed of iron sulphide.

a common mineral (iron disulfide) that has a pale yellow color

A hard, heavy, shiny, yellow mineral, FeS2 or iron disulfide, generally in cubic crystals. Also called iron pyrites, fool's gold, sulfur balls. Iron pyrite is the most common sulfide found in coal mines. Return to the top of the page. QUATERNARY : A geological period dating from about 1.8 million years ago to the present. Return to the top of the page. RECLAMATION : The restoration of land and environmental values to a surface mine site after the coal is extracted. Reclamation operations are usually underway as soon as the coal has been removed from a mine site. The process includes restoring the land to its approximate original appearance by restoring topsoil and planting native grasses and ground covers.

The natural sulfides of certain metals. The most common is iron pyrite, which is iron disulfide (FeS2), a brittle mineral that is a brassy yellow in color with greenish-black streaks.

Any of various native metallic sulfides. This term generally refers to iron pyrite. Rankine is an absolute temperature scale often used in engineering. Using this scale, the freezing point of water is 492°R and the boiling point of water is 672°R.

Is Iron Pyrite and also known as Fools Gold

A common yellow isometric mineral, FeS2. It has a brilliant luster and an absence of cleavage, and has often been mistaken for gold . It is commonly referred to as "fool's gold"

FeS. Referred to as “fool's gold” because of its brassy color, it is a common accessory mineral in sulfide -rich ore deposits. See also the field guide entry for pyrite.

FeS2 a common mineral that participates in permineralization

Iron sulfide. Compact granular aggregates. Opaque with bright metallic luster. (6 - 6.5)

a mineral form of iron sulfide, FeS.

A common mineral composed of iron disulphide with a pale brass-yellow color used as an iron ore and in the production of sulfur dioxide for sulfuric acid. Also called Fool's gold and Iron pyrite.

A common, pale-bronze or brass-yellow, isometric mineral. It is dimorphous with marcasite, and often contains small amounts of other metals. Pyrite has a brilliant metallic luster and an absence of cleavage, and has been mistaken for gold. Pyrite is the most wide-spread and abundant of the sulfide minerals and occurs in all kinds of rocks, such as in nodules in sedimentary rocks and coal seams or as a common vein material associated with many different minerals.

A common metallic mineral comprising iron disulphide (FeS2). Crystallizing in the isometric system, pyrite is opaque and has a pale brass-yellow colour, metallic luster, and commonly occurs as cubic or octahedral crystals. Pyrite may occur as nodules or as finely disseminated crystals in sedimentary rocks, and may also replace fossils.

Sulphide of iron. A common ore containing about 53% sulphur and 46.7% iron. Commonly occurring in mineral deposits, its chief use is for the manufacture of sulphuric acid for which purpose it is roasted to obtain the sulphur as sulphur dioxide in the gaseous state.

Iron sulfide mineral (FeS). Forms silvery to brassy metallic cubes or masses. Common in many rocks. Known as fool's gold. Weathered pyrite produces limonite (iron oxide) that stains rock brown. or yellow.

an iron sulfide mineral

A metallic, pale yellow, cubic mineral composed of iron and sulphur.

an iron sulphide, FeS

A name for many compounds of metals with sulpher or arsenic, especially iron pyrites or copper pyrites. Pyrite is brassyellow and brittle, but because of its color, is often mistaken for gold, hence the name "fool's gold."

yellow and lustrous form of iron disulfide

A yellow iron sulphide mineral, normally of little value. It is sometimes referred to as "fool's gold".

A very common iron sulphide mineral (FeS2).

iron sulphide mineral, FeS

A yellowish mineral, iron disulfide (FES2) commonly found in coal beds and associated rocks, that results in acid drainage when it comes into contact with air and water.

Pyrite (also known as fool's gold) is a shiny, metallic mineral that is a form of iron.

A hard, heavy, shiny, yellow mineral, FeS2 or iron disulfide, generally in cubic crystals. Also called iron pyrites, fool's gold, sulfur balls. Iron pyrite is present in large quantities at the Molycorp mine site. To top

or pyrites: originally any "fire-stone" from which sparks could be struck; eventually an iron sulfide or iron-copper sulfide. [ T. Thomson

a pale yellow to brass-yellow metallic material that will often tarnish with brown film of iron oxide. Has a hardness of 6-6.5. Pyrite is well known as "foo'ls gold" so called because it is easily mistaken for native gold. Sources: Throughout North America.

(1588) A common mineral consisting of iron disulphide found in blocks, gravel and crystals, pyrite is a pale brass-yellow or golden-yellow colour with a metallic lustre. The paler collared variety found in unusual shaped crystals are known as Marcasite.

FeS2 Pyrite is a metallic mineral composed of iron and sulfur. It forms in a wide range of environments including hydrothermal veins and igneous rocks, in slates, and in shales. The crystals appear in a variety of forms: striated cubes, pyritohedral crystals, radiated disk forms, and pyritized fossils. known as "Fool's Gold", it is the most common sulfide mineral and occurs worldwide. Pyrite was used by ancient Greeks and Romans for mirrors and jewelry. Sources include the United States, Spain, and Italy.

A gold-colored mineral composed of iron sulfide. It is informally known as "fool's gold."

Natural pyrite has a brassy appearance and it sometimes confused for gold. It has little or no gold content and is often called “fool’s gold.” Used by jewelers for thousands of years, pyrite has been found in ancient Greek jewelry and the tombs of Incas. Marcasite jewelry is actually pyrite.

Iron disulfide (FeS2 ). A common mineral that has a bright metallic luster and a brass-yellow color.

a common yellow mineral with a metallic luster, a compound of iron and sulfur, which resembles and is often mistaken for gold; fool's gold. It is used to make sulfuric acid. [AHDOS

The mineral pyrite, or iron pyrite, is iron sulfide, FeS2. It has isometric crystals that usually appear as cubes. The cube faces may be striated (parallel lines on crystal surface or cleavage face) as a result of alternation of the cube and pyritohedron faces.
