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 strain ellipsoid original shape
Metamorphic petrology • Metamorphic agents: T, P, and/or fluid • Pressure as deviatoric stress • Tensional, compressional, shear
Metamorphic petrology • Metamorphic agents: T, P, and/or fluid • Pressure as deviatoric stress • Tensional, compressional, shear
Types of metamorphism • Contact met. • Adjacent to igneous rocks
Types of metamorphism • Regional met • Convergent margins
Types of metamorphism • Burial met • Sed basins
Types of metamorphism • Ocean-floor met
Types of metamorphism • Shear zones
