In this chapter, we show how the major-element compositions of magmas are controlled by mass balance during their evolution through various processes such as crystallization, melting or mixing, including some variants thereof. Mass balance implies specific numerical and graphical relations (the “lever rule”) that can be used to predict the evolution of melt in any of these scenarios.
