Refer to Fig. 3.3 Which has been introduced as the order of crystallization of minerals out of a mafic magma. More specifically, it is known as Bowen’s Reaction Series, with one side depicting discontinuous reactions of minerals with the remaining magma and the other side depicting a continuous reaction of minerals with the remaining magma. What does it tell us about (a) plagioclase and (b) olivine, pyroxene, and hornblende?
