The presence of Fe oxides in different forms and quantities is the predominant cause of the magnetic properties of soils. Iron oxide minerals can be both pedogenic (product of soil formation) and lithogenic (unweathered minerals from the parent material) in origin. Iron is the most common element in the crust of the earth.
