Metamorphic Rocks

Learn about the agents of metamorphism, types of metamorphism, and different metamorphic rock types. Discover how heat, pressure, and chemically active fluids transform parent rocks into foliated and non-foliated metamorphic rocks. Explore the rock cycle and understand the changes that occur in the metamorphic process.

  1. Metamorphic Rocks “change”

  2. I. Agents of Metamorphism

  3. I. Agents of Metamorphism • A.  Heat • B.   Pressure • C.Chemically Active Fluids

  4. II. Types of Metamorphism • A.  Contact “baking and CAF”

  5. II. Types of Metamorphism • A.  Contact • B.  Regional “heat, pressure, CAF”

  6. II. Types of Metamorphism • A.  Contact • B.  Regional • C. Dynamic “along fault zones”

  7. A mylonite formed from dynamic metamorphism

  8. III. Metamorphic Rock Types A.  Foliated (regional meta.) B. Non Foliated(regional or contact meta.)

  9. A.  Foliated

  10. A.  Foliatedfoliated rocks require heat, pressure, and Chem. Active fluids. Parent Rock >>>>>>>> Meta. Rock

  11. A.  Foliatedfoliated rocks require heat, pressure, and Chem. Active fluids. Parent Rock >>>>>>>> Meta. Rock Granite………………….

  12. A.  Foliatedfoliated rocks require heat, pressure, and Chem. Active fluids. Parent Rock >>>>>>>> Meta. Rock Granite………………….Gneiss

  13. A.  Foliated Parent Meta. Rock >>>>>>>> Rock Shale >>>>>>>>

  14. A.  Foliated Parent Meta. Rock >>>>>>>> Rock Shale >>>>>>>> Slate

  15. A.  Foliated Parent Meta. Rock >>>>>>>> Rock Shale >>>>>>>> Slate……Phyllite

  16. A.  Foliated Parent Meta. Rock >>>>>>>> Rock Shale >>>>>>>> Slate……Phyllite…..Schist

  17. A.  Foliated Parent Meta. Rock >>>>>>>> Rock Shale >>>>>>>> Slate……Phyllite…..Schist…..Gniess

  18. A.  Foliated Parent Meta. Rock >>>>>>>> Rock Low Grade………………High Grade Shale >>>>>>>> Slate……Phyllite…..Schist…..Gniess

  19. A.  Foliated Low Grade………………High Grade Slate……Phyllite…..Schist…..Gniess

  20. A.  Non FoliatedNeed either Heat and CAF, or H,P,CAF Parent Meta. Rock >>>>>>>> Rock Limestone >>>>>>>>

  21. A.  Non Foliated Parent Meta. Rock >>>>>>>> Rock Limestone >>>>>>>> Marble

  22. A.  Non Foliated Parent Meta. Rock >>>>>>>> Rock Sandstone >>>>>>>>

  23. A.  Non Foliated Parent Meta. Rock >>>>>>>> Rock Sandstone >>>>>>>> Quartzite

  24. A.  Non Foliated Parent Meta. Rock >>>>>>>> Rock Mafic Ign Rock >>>>>>>>

  25. A.  Non Foliated Parent Meta. Rock >>>>>>>> Rock Mafic Ign Rock >>>>>>>> Soapstone, Amphibolite, or Greenstone

  26. A.  Non Foliated Parent Meta. Rock >>>>>>>> Rock Bituminous >>>>>>>> Coal

  27. Parent Meta. Rock >>>>>>>> Rock Bituminous >>>>>>>> Anthracite Coal Coal

  28. A.  Non Foliated Parent Meta. Rock >>>>>>>> Rock ONLY HEAT AND CAF Shale …………. Hornfels
