Marcasite has the same chemical formula(FeS<sub>2</sub>) as pyrite. They are not considered the same mineral because they are classified into different crystal systems. SO even though marcasite may have the same elemental composition, it is different. The two minerals are often accidentally confused for one another. <ref name=themineralpyrite> [http://www.minerals.net/mineral/pyrite.aspx THE MINERAL PYRITE] ''The Mineral and Gemstone Kingdom''.
