Transcript of "Metamorphic rocks"

  1. 1. Meta=change Morphic=form/shap e
  2. 2. I. Parent Rocks Rocks that have been changed from an original “parent” rock
  3. 3. II. How are Metamorphic Rocks Formed?  Formed under tremendous heat, great pressure, and chemical reactions  Can make new minerals  Most are found on or near plate boundaries  Metamorphism is changing one type of rock into another as a result of heat(from mantle), Pressure (from layers above) and/or chemical reactions.
  4. 4. III. Where does the Heat Come From? The heat comes from: 1. Mantle 2. Pressure of the layers 3. Movement of the Plates on Earth
  5. 5. IV. What does Metamorphism change?  Metamorphic rocks can change: 1. a rocks appearance, texture 2. crystal structure 3. mineral content  It can form from a/an: 1. Igneous 2. Sedimentary 3. Another metamorphic rock!
  6. 6. a. Foliated – mineral crystals are arranged in parallel layers or bands Examples: Schist, slate, and gneiss b. Nonfoliated – rocks are not banded and do not break into layers Examples: Marble and quartizite V. Types of Metamorphic Rocks
  7. 7. Foliated
  8. 8. Non-foliated NON-Foliated
  9. 9. VI. Contact vs. Regional Metamorphism Contact Small Area Regional Large Area

  12. 12. Tier 1 Metamorphic Picture  1 picture of foliated  1 picture of non- foliated  Must have correct rock names  Must be presented in an organized/colorful way Chart  Complete chart  Must do research  DOES NOT have to be colorful
