Pyrite is a mineral belonging to the pyrite group. Pyrite is a very common mineral found in many different formations of rock. Since pyrite has a similar color to gold, so many in the past have confused it with being gold and now the most common name of pyrite is fool's gold.

Color is often useful, but should not be relied upon. Different minerals may be the same color. Real gold, as seen in Figure 2, is very similar in color to the pyrite in Figure 1. Additionally, Some minerals come in many different colors. Quartz, for example, may be clear, white, gray, brown, yellow, pink, red, or orange....

Pyrite Mineral Information photos and Facts, Fools Gold

Pyrite is the most common of all the sulphides. It is a common vein mineral, occurring in rocks of all ages and associated with many different minerals. Found frequently with chalcopyrite, sphalerite, galena, etc. Pyrite crystals are so widely distributed that but very few of its most important occurrences may be mentioned here. In the mines of

Pyrite has the same chemical formula as the rarer mineral Marcasite, but it crystallizes in a different crystal system, thereby scientifically classifying it as a separate mineral species. Aggregates of iron sulfide (FeS 2 ) where the crystal structure cannot be determined without complex analyzing material may be wrongly labeled by dealers....

Pyrite often forms perfect cubes, which can grow to quite large sizes, because of its crystal structure. The word pyrite comes from the Greek word 'pyr' meaning fire, because it will spark if hit with other metal or stone objects.

What Type of Rock Is Pyrite? | Reference

Pyrite's name comes from Greek and alludes to the fact that sparks form when it strikes iron. Pyrite goes into forming igneous, metamorphic and sedimentary rock. It is often found in crystals of various shapes and is often dark yellow and lustrous.

Pyrite is quite easy to distinguish from gold: pyrite is much lighter, but harder than gold and cannot be scratched with a fingernail or pocket knife. Pyrite is commonly found to contain minor nickel, and forms a series with Vaesite; Bravoite is a nickeloan variety of pyrite. It usually contains minor cobalt too and forms a series with Cattierite....

Pyrite can form in extremely well-crystallized examples of cubes, pyritohedrons, and octahedrons. Combinations of these forms also occur. An icosahedron formed from a combination of an octahedron and pyritohedron is also known. Pyrite crystals frequently form penetration twinning, especially in the cubic form.

The photo shows a crystal of blue euclase with striations on its faces that parallel the long axis of the crystal.

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 ....

Why does pyrite form cubic crystals? Chemistry Stack

4 Answers. The molecular shape does not necessarily mean that the pyrite crystal has a cubic shape, however if the conditions are right (pressure and temperature), and the composition is 'correct' if the formation is in a iron rich environment (as per the first reference), then this molecular shape could express as a cubic crystal.
