"Hi this is Jane Stammer from the Colorado School of Mines and I'm here to answer questions on what makes rocks red. Rocks are red when they contain the mineral hematite. Hematite is a iron oxide. Iron in the mineral hematite is in it's oxidized state and similar to rust that you would find on a car or some other material when iron is oxidized it forms a reddish hue and the mineral hematite contains iron in this state. And that is what makes rocks red."
