Why does the mineral pyrite have many shapes?

Pyrite can form in a myriad of different crystal habits. Primary pyrite habits such as framboid, colloform and spheroidal textures are those most often associated with growth in soft sediments. Cubes and the more characteristic forms are associated with increased P-T conditions and recrystallisation ( Full Answer )

What is pyrite?

Pyrite is iron sulfide, a mineral composed of sulfur and iron. It's also known as "Fools'Gold" because of its shiny yellowish metallic luster. Pyrite can be found in sedimentary, magmatic, and metamorphic rock deposits, and also in hydrothermal vents, wherever there is sulfur and iron. . Pyrite ( Full Answer )

Where is pyrite from?

That is a rather vague question. Pyrite can be found in virtually every rock type as well as formed within bacteria and meteorites. So you could say it will form almost everywhere given the right conditions.

How does the color of the streak comepare to the color of the mineral?

The streak many not match the visual color whatsoever. That is whyyou must do the test. For example, I streaked a piece of specularhematite yesterday, which was a very dark, (nearly black), metalliccolor. It streaked red though, as all hematites do.

What color are pyrite?

To the naked eye, it appears golden, with a negligibly less yellow tint. When scraped on a ceramic streak plate, it appears dark green, since the particles on the plate aren't able to reflect light like their original crystallized form.

How could you determine if a mineral is pyrite or gold?

There are differences in weight, streak, melting point, hardness and other characteristics that make it fairly easy to distinguish. The easiest way to determine which mineral it is, is probably by streak test. Rub the mineral across the unglazed side of a porcelain tile's surface. Pyrite will leave ( Full Answer )

What is pyrite the mineral used for?

How could you determine if a mineral is pyrite or?
