Marcasite mineral.

The mineral marcasite, sometimes called " white iron pyrite ", is iron sulfide (FeS 2) with orthorhombic crystal structure. It is physically and crystallographically distinct from pyrite, which is iron sulfide with cubic crystal structure. Both structures contain the disulfide S 22− ion, having a short bonding distance between the sulfur atoms.Oxygen and Hydrogen Isotope Relationships in Hydrothermal Mineral . 229: 41 . 290: Hydrothermal Alteration and Its Relationship to Ore Fluid Composition . 303: Graphic Display of Mineral Relationships . 313: 63 . 359: Sulfide Ore Mineral Stabilities Morphologies and Intergrowth Textures . 367:Goethite—The brown oxide mineral of soils and iron ore.
