1. For the three points A, B, and C,
What are the existing phases & number of them
Calculate the degrees of freedom
What mineral do you expect from a contact metamorphic rock? Reasons?
If your thinsection has all the three phases stably coexisting, what are the temperature and pressure condition the rock experienced?

2. 5 3 4 1 2 4 3 7 1 6

3. From the given T-X diagram,
Fill in an appropriate SCM ternary diagram for each number
Observe the given thin section and match the assemblage of the sample to that of the phase diagram
What was the temperature of the metamorphism your sample experienced?
