EOSC 322 · Metamorphic Petrology

Deciphering lithospheric processes as recorded by the mineralogy, chemistry and textures of metamorphosed rocks. [2-3-0] Prerequisite: EOSC 221.

Course Availability & Schedule

Learning Goals

  1. Apply principles of equilibrium thermodynamics to evaluate the conditions for formation of metamorphic mineral assemblages.
  2. Assess petrogenetic evolution and Pressure-Temperature-time progression from metamorphic rock textures and mineral assemblages.
  3. Relate changes in mineral content and texture across a metamorphic suite or map area to processes of metamorphism.
  4. Differentiate mineralogical changes due to variable bulk composition from those that result from temperature, pressure, and imposed chemical potential.
  5. Describe using metamorphic processes, the mechanisms by which heat, mass and fluid are transported in the Earth’s crust, and relate them to their plate tectonic environment.
