A slice of what is called "BIF", Banded Iron Formation. This is iron ore composed of metamorphosed layers of both Magnetite (black) and Hematite (red). There is also Goethite and Quartz. BIF usually contains at least 15% iron in some form and is thought to have formed by submarine volcanic activity during the Precambrian.
