The study of paleomagnetism is possible because iron-bearing minerals such as magnetite may record past directions of the Earth's magnetic field.

The colors are the result of the oxidation of iron-bearing minerals in the Hakatai Shale.

He developed a process of crushing and milling iron-bearing minerals and separating iron ore from the material through large electromagnets.

The environment of deposition was moist and humid, resulting in the sandstone's red color due to the alteration of iron-bearing minerals.

In Table 2 are given susceptibilities for some iron-bearing minerals.

One instrument identifies iron-bearing minerals by looking at the scattering of gamma rays - a high-energy form of light - off the rock.

China stone is a medium grained, feldspar-rich partially decomposed granite characterized by the absence of iron-bearing minerals.

Astronomers combined images of Vesta in two colors to study the variations in iron-bearing minerals.

The iron-bearing minerals when present are strongly magnetic and can be removed through a magnetic field.

Oxidation of these iron-bearing minerals causes Westchester marble to turn orange-brown when the stone is exposed to weather.
