Iron formation Iron oxidation Iron isotopes Hematite Magnetite Pyrite ABSTRACT The origins of iron formations remain somewhat enigmatic despite much progress over the past decades. This is due in part to continuing research demonstrating that these deposits do not have a single origin but rather can be formed under various and variable conditions.

Pyrite seldom forms in freshwater environments. The formation of pyrite crystals depends mainly on the iron content of the sediment. The process of pyrite formation in sediments results from the action of bacteria, which reduce sulphate ions (dissolved in the pore water) to sulphide. If there is iron present, iron .

28/01/2012 · Magnetite iron is in +2 and +3 oxidation states whereas, in hematite, it is only in +3 oxidation state. This is the key difference between magnetite and hematite. Moreover, magnetite has higher iron content than hematite; therefore, its quality is higher. Apart from that, in colours too, there is a difference between magnetite and hematite.
