A phase diagram is a graph that shows the distribution of stable phase assemblages as a function of the values of the intensive variables used to describe the thermodynamic system. (more on this in Chapter 9). Phase diagrams are powerful analytical tools in many branches of planetary sciences, as they provide a way to quickly visualize how sp.info Callister:Materials Science and Engineering:An Callister:Materials Science and Engineering:An Introduction, 6th Edition.
