7. geophysical characteristics of volcanogenic massivethe most common sulfide mineral in vms deposits is pyrite, which is often associated with other sulfides such as pyrrhotite, chalcopyrite, sphalerite, and galena (galley and others, 2007). other possible nonsulfide minerals associated in vms deposits include magnetite, hematite, and cassiterite; barite can be present as a gangue mineral.sulfide mineral summary britannicasulfide mineral, or sulphide mineral, any member of a group of compounds of sulfur with one or more metals.the metals that occur most commonly are iron, coppersulfide minerals slidesharemar 28, 2015· the sulfide minerals represent higher temperatures and a slightly deeper setting than the sulfate minerals, which reflect the oxygen rich environment near the earth's surface. 4. sulfides occur as primary accessory minerals in many different igneous rocks and in deep hydrothermal deposits that are closely related to igneous intrusions.sulphide or sulfide? mindat.org mines, minerals and moreaug 28, 2009· mineral names = ima naming * chemical names = iupac naming as has been pointed out this means we have the mineral sulphur which is composed of elemental sulfur. so, the answer to the original question is 'sulfate/sulfide' and believe me, as a brit, it really upsets me tosulfide mineral wikipediaoverviewmineralsnickelstrunz classification 02 sulfidessee alsoexternal linkscommon or important examples include
