Understanding how the reaction series was derived is key to understanding what it means. Norman Levi Bowen (Figure 7.7) was born in Kingston Ontario. He studied geology at Queen’s University and then at … See more Bowen’s reaction series (Figure 7.6) has two pathways for minerals to form as magma cools: on the left is the discontinuous series. … See more The composition of the original magma determines how far the reaction process can continue before all of the magma is used up. In other … See more WebThe minerals that make up igneous rocks crystallize (solidify, freeze) at a range of different temperatures. This explains why cooling magma can have some crystals within it and yet remain predominantly liquid. The …
