Pyrite. Commonly called fool's gold, pyrite is the Earth's most abundant sulfide mineral. Recognized for its brass-yellow color which resembles that of gold, pyrite is a source of iron and sulfur and is used for the production of sulfuric acid.
The name pyrite comes from pyrite lithos, which, in Greek, means 'stone which strikes fire' in reference to the tendency of the mineral to spark when struck against steel. In fact, pyrite was used for that purpose in early flintlock rifles.
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 sedimen…tary, magmatic, and metamorphic rock deposits, and also in hydrothermal vents, wherever there is sulfur and iron. . Pyrite ...
Location: Pyrite is found in many places around the world with large mineral deposits in Italy, France, Spain (famous here for its beautiful single cubes of pyrite), Peru, Bolivia, Mexico, Romania, Sweden, Norway, Germany, Japan,
Cathedral pyrite is the mineral in larger gothic-like markings and crystals, which explains its name "cathedral" (2). Bravoite is is pyrite with a nickel-cobalt bearing, with nickel, Ni 2, substituting the Fe 2 in the pyrite mineral composition (2).
In fine-grained or organic-rich sedimentary rocks, pyrite may even form discrete pyrite concretions or flattened discs called 'pyrite dollars'. In calcite and quartz veins, pyrite is commonly associated with chalcopyrite and other sulfide minerals and metallic ores.
Fracture is the characteristic way a mineral breaks. The difference between cleavage and fracture is that cleavage is the break of a crystal face where a new crystal face is formed where the mineral broke, whereas fracture is the "chipping" of a mineral.

Cleavage and Fracture Cleavage is the way a mineral breaks. Many minerals break along ﬂat planes, or cleavages—some in only one direction (like mica), others in two directions (like feldspar), and some in three directions (like calcite) or more (like
