  1. Physical Geology LaboratoryTuesdayTom Burbinetomburbine@astro.umass.edu

  2. Midterm • Next Tuesday • Covers all the labs from September 8th to October 12th • You can bring in the mineral identification sheets that you filled out in class

  3. Metamorphic Rocks • Rocks changed by intense heat, intense pressure, or the action of watery hot fluids • Every metamorphic rock has a parent rock

  4. Scales • Contact metamorphism – occurs locally • Adjacent to igneous intrusions or along fractures that are in contact with watery hot fluids • Low to moderate pressure • Regional metamorphism – occurs over very large areas • Generally accompanied by folding of rock layers • Moderate to extreme pressure and heat associated with deep burial or tectonic movements of rock and/or widespread migration of hot fluids from one region to another

  5. Texture • Foliated - Layering • Nonfoliated - no obvious layering

  6. Any Questions?
