Metamorphic petrology l.jpg
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
