It forms at high and low temperatures and occurs, usually in small quantities, in igneous, metamorphic, and sedimentary rocks worldwide.Apr 1, 2019 · Galena, historically also named lead glance, is among the most abundant sulfides. Besides forming aesthetic mineral specimens, galena is the primary lead ore. And galena itself was a first semiconductor ever used. Crystal Structure of Galena. The chemical formula of galena is PbS (lead sulfide). A key step in the reactions of all the sulfide minerals is that they release iron as ferrous ion (Fe2+). Oxygen present in the water can then oxidize Fe2+ back to Fe3+: 2Fe2+ + 1 2 O2 + 2H+ → 2Fe3+ +H2O (8) (8) 2 Fe 2 + + 1 2 O 2 + 2 H + → 2 Fe 3 + + H 2 O. This Fe3+ can again react with the mineral surface.Muscovite is the most common mineral of the mica family.
