Presentation Transcript

  1. Examples of Foliation Phyllite Gneiss

  2. Examples of Foliation Slate

  3. Examples of Nonfoliated or Granular Texture Marble Quartzite

  4. Regional Metamorphism Example low grade intermediate grade high grade

  5. Metamorphic Grade In nonfoliated metamorphic rocks, larger individual minerals and a dense, interlocking arrangement of minerals and rock components indicate a high grade rock

  6. Common Metamorphic Index Minerals Take notes! Talc Chlorite Zeolites Low Grade Epidote Actinolite Tremolite Hornblende Glaucophane Garnet Medium to Low-high Grade amphiboles

  7. Metamorphic Rocks • As in the sedimentary rock lab, if I ask you for a complete name for the rock, write the names of the minerals you observe (least – most abundant) prior to the rock name • e.g., biotite – potassium feldspar – quartz gneiss
