Marcasite: The mineral marcasite information and pictures
Marcasite is the lesser known companion of the famous mineral Pyrite.Marcasite has the same chemical formula as Pyrite, but crystallizes in a different crystal system, thereby making it a scientifically distinct mineral species. Aggregates of iron sulfide (FeS 2) where the crystal structure cannot be determined without complex analysis may be wrongly labeled by dealers and collectors.Marcasite Mineral | Uses and Properties,Geologic Occurrence of Marcasite. Most marcasite forms in one of three ways: 1) as a primary sedimentary mineral; 2) as a product of low-temperature hydrothermal activity; and, 3) as a secondary mineral that forms during the alteration of other sulfides such as pyrrhotite or chalcopyrite.Most conditions of marcasite formation are at relatively low temperatures and elevated acidity.YupRocks - Pictures of the Mineral Marcasite,Marcasite, also called a Pyrite of white iron has a crystal structure relating to the orthorhombic form, and is a sulfide of iron (FeS2). You have to remember that this mineral is different from Pyrite in both its crystallography and its physical characteristics. The similarity between the two lies in the iron of disulfide S22 that brings about the sulfur atoms to retain a short bonding length.Marcasite: Mineral information, data and localities.,Marcasite Group. The orthorhombic polymorph of isometric (cubic) pyrite.A common natural disulfide. Compare UM1997-43-S:Fe. Crystals common, metallic pale brass-yellow colored, tabular or pyramidal, often with curved faces; it may also be stalactic, globular, or reniform with a radiating internal structure.MARCASITE (Iron Sulfide) - Amethyst Galleries' Mineral Gallery,Marcasite, whose name is derived from the Arabic word for pyrite, is a common and an attractive mineral. The two minerals, marcasite and pyrite, are often confused due to their similar characteristics. Marcasite is a polymorph of pyrite which means that it has the same chemistry as pyrite but a different structure and, therefore, different,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 these di-anions are arranged around the Fe cations. Marcasite is lighter and more brittle than pyrite. Specimens of marcasite often cr…
