Phase diagrams in the geological literature are often plotted in terms of weight percentages, whereas phase diagrams in the Calculate the molar percentages of anorthite and diopside at the eutectic composition. We call anorthite component A because it melts at a higher temperature than diopside. Figure 2. Forsterite-Anorthite phase diagram. Figure 3.
