Mineralogy of Sulfides Elements

Several hundred sulfide minerals are known, but only five are sufficiently abundant accessory minerals to have been categorized as rock forming (Bowles et al. 2011). These five are pyrite, pyrrhotite, galena, sphalerite and chalcopyrite, and it is the iron sulfides (pyrite and pyrrhotite) which are dominant.

The Determination of Sulfate and Sulfide Sulfur in Rocks

A method for the determination of sulfate and sulfide sulfur that occur together in rocks or minerals is presented. All the sulfate sulfur is converted to barium sulfate in an inert atmosphere to prevent oxidation of any sulfide sulfur.

Bravoite is the name given to a nickel rich iron sulfide. It is closely related to pyrite but contains up to 20% nickel. Some mineral books treat it as a variety of pyrite. Pyrite is a polymorph of marcasite, which means that it has the same chemistry, FeS2, as marcasite; but a different structure and therefore different symmetry and crystal shapes. Pyrite is difficult to distinguish from marcasite when a lack of
