Marcasite Wikipedia

The mineral marcasite, sometimes called “white iron pyrite”, is iron sulfide (FeS2) with orthorhombic crystal structure. It is physically and crystallographically distinct from pyrite, which is iron sulfide with cubic crystal structure. Both structures do have in common that they contain the disulfide S2 ion, having a short bonding distance between the sulfur atoms. The structures differ in how t
