The metallogenic history of the Birimian shows a three-phase evolution coinciding with the orogenic evolution, and extends over almost 150 Ma from the Perkoa massive (Zn-Ag) sulfides (2.12 Ga) with a clear mantle affinity to the late- mesothermal Au quartz veins ( ~ 2 Ga) with (according to lead isotopes) a high crustal participation.

They are composed of alternating layers of iron-rich material (commonly magnetite) and silica (chert). How old are banded iron formations in Michigan? The Banded Iron Formations (BIFs) are about 2 billion years old and are made of alternating layers of Magenetie (Fe3O4) or Hematite (Fe2O3) which are the grey shiny layers, and red layers of iron stained chert (SiO2) often

Naturally-magnetized pieces of magnetite, calledlodestone, will attract small pieces of iron, which is how ancient peoples first discovered the property of magnetism. Today it is mined as iron ore. The chemical IUPAC name is iron (II,III) oxide and the common chemical name is ferrous-ferric oxide. How magnetite is formed?

Graphite which occurs in the early Precambrian banded iron formation (BIF) (3.1x10 9 yr) at Gongchangling, Anshan, China, can be divided into two genetic types on the basis of its modes of occurrence: biogenic and inorganic; the former occurs in garnet-mica-quartz schist and the latter in rich magnetite ore.. The garnet-mica-quartz schist is located at the bottom of the formation.
