Abstract
This chapter is concerned with metamorphic reactions that produce new minerals at the expense of reactant minerals in the protolith. Many of these reactions are useful thermometers and barometers. It is possible for the metamorphic petrologist to deduce the evolutionary history of a metamorphic complex in terms of pressure–temperature–time (or P–T–t) path. These topics and a brief presentation on metamorphic rocks are made in this chapter.

Notes
- 1.
Boudins are resistant (“competent”) blocks that break apart and resist ductile deformation. In UHPM occurrences such boudins appear as a long chain of “necked” or discontinuous broken blocks surrounded by highly deformed matrix.
