36 diopside anorthite phase diagram

To introduce phase diagrams, we will consider the characteristics of a series of phase diagrams of increasing complexity, beginning with a binary mixture of diopside and anorthite, at 1 atm pressure. Figure 6-1. Some important elements of this phase diagram include its The system diopside -forsterite anorthite is an example of a system containing a pyroxene, an existing among these silicate types that the system diopside- forsterite. phase equilibria in the 1.

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.
