This Video Lecture Contains Introduction to.
1. Binary Phase Diagrams
2. Two Component System
3. Phase Diagram of Solid Solution Plagioclase/ Albite- Anorthite System
4. Lever Rule Concept.
5. Numerical for better understanding
6. Phase stability diagram for plagioclase, the most abundant mineral group
in Earth ’ s crust. One critical line on the phase stability diagram is the high temperature, convex upward liquidus line, above which is the all liquid (melt) stability field that comprises the conditions under which the system
is 100% liquid (melt). A second critical line is the lower temperature, convex downward solidus line, below which is the all solid stability field that comprises the conditions under which the system is 100% solid.
