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.

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.

Johnathan Hill used the name marcasite in 1771, but his usage was also indiscriminate and was a term for any massive "pyrites" or "mundic". In 1845, Wilhelm Karl von Haidinger defined marcasite as the mineral is known today. Marcasite Group. The orthorhombic polymorph of isometric (cubic) pyrite. A common natural disulfide.

What is Marcasite? (with picture) - All Things Nature

Marcasite is a mineral formed from iron sulfate. It is occasionally called white pyrite, but is not pyrite, or fool’s gold, as it is sometimes called. To further confuse matters, most gems called marcasite, are in reality pyrite. True marcasite disintegrates quickly and does not keep well in gem form.

Marcasite Mineral Uses and Properties

2020-8-17  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.
