Different minerals weather and break down at different rates depending on how stable or reactive they are at the surface of the Earth. A given mineral's stability or reactivity at the surface of the Earth can be predicted from the conditions in which it formed. For minerals that form in igneous rocks, the closer the the conditions of formation are to conditions at the earth's surface, the more stable the mineral. We can relate this concept back to Bowen's Reaction Series.
