In this chapter we discuss how magmas differentiate to produce the wide range of igneous rocks. Many processes have been invoked, but fractional crystallization is undoubtedly the most important of these. After dealing with the chemical evidence for fractional crystallization, we discuss the actual mechanisms by which crystals can be segregated from liquid in magmas. Historically this was thought to be due to gravitative crystal settling.
