Metamorphic petrology

• All about mineral stability and reactions
• Metamorphism solid change of form
• Change mineralogy, texture, composition
• Occurs between diagenesis and melting

Metamorphic petrology

• Metamorphic agents T, P, and/or fluid
• Pressure as deviatoric stress
• Tensional, compressional, shear
