Metamorphism
Temperature and pressure within the earth
Recrystallization due to changes in heat, pressure, and fluids
Contact vs. Regional Metamorphism
Control of parent rock (precursor)
Types of Metamorphic Rocks
Foliated
Slate, Schist, Gneiss
Unfoliated
Marble, Quartzite, Hornfels
Examples of Mineral Reactions
Graphite to diamond
Kyanite, andalusite, and sillimanite
