Main Features:
    Pyrite is a metallic mineral that is composed of iron and sulfur atoms bound together in a ratio of one iron to two sulfur,
and it is arguably the most abundant sulfide mineral on Earth.
     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.
The mineral is found in many sedimentary rocks, such as limestone, shale and coal, as well as in metamorphic rocks like schist.
     It is a very common mineral in ore deposits, where it is found along with other metal-containing minerals, including gold. And yet pyrite is not mined for its iron, as the metal is difficult to extract from it.
     In some rocks, usually shale, pyrite forms pyritized fossils, where the pyrite replaces shell material inside the fossil. An example of a pyritized fossil is shown in this picture of a cephalopod fossil.
