The earth's crust lower mantle is made up of silicate perovskites and ferropericlase. While the silicate perovskites are the names given to calcium silicates and magnesium iron, ferropericlase is an oxide of magnesium/iron. The lower mantle is at a depth that ranges from 650 kilometers to 2,890 kilometers.
