Developments in Iron Ore Exploration Banded Iron ...

It is no surprise that the first application of geophysics in mineral exploration was the search for iron. The method used to detect magnetic minerals, the magnetic method, has had a long and involved gestation period. From its first reported use as a "bump finder," the magnetic method has evolved to become the mainstay of iron exploration.

Banded Iron Formation - an overview ScienceDirect

Banded iron formation (BIF) is both the most easily identifiable of all sedimentary rocks and the one whose origin is most enigmatic. Its flamboyant mesoscale banding is defined by planar variations in the proportions of the two main mineral components – quartz and iron oxides – each of which forms about half of the mass of the rock.
