Metaphysical Properties of Banded Iron from Wyoming USA

Graphite which occurs in the early Precambrian banded iron formation (BIF) (3.1x109yr) at Gongg, 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.

origion of banded magnetite quartz ore

Introduction. Banded iron formations (BIFs), typically thin bedded or laminated, are chemical sediments containing >15 wt% Fe 2 O 3 and composed of intercalated microcrystalline quartz, iron oxides (e.g., hematite and magnetite), silicates and carbonates (e.g., siderite, ankerite and dolomite) (James, 1954, Pickard, 2003, Basta et al., 2011, Cox et al., 2013).
