Rocks -igneous_sedimentary_&_metamorphic[1]

  1. 1. Rocks: Igneous, Sedimentary & Metamorphic
  2. 2. Igneous: Compare color & texture Color: Felsic vs Mafic Texture: Fine vs Coarse
  3. 3. Color: Mafic - Dark color Felsic - Light color Igneous: Compare color & texture
  4. 4. Igneous: Compare color & texture Texture: (crystal size) Coarse Intrusive - cooled slowly Fine Extrusive - cooled quickly
  5. 5. Igneous: Compare color & texture Rock Identification is: 1 Granite 2 Basalt 3 Rhyolite 1 2 3
  6. 6. Sedimentary: Clastic Bioclastic Stratification
  7. 7. Sedimentary: Clastic Bioclastic Stratification <ul><li>3 </li></ul>Clastic - Made of Sediments ex: 1 & 2 1 2 4 Bioclastic - Has coal or shells ex: 3 & 4 Stratification - Shows layering ex: 2
  8. 8. Sedimentary: Clastic Bioclastic Stratification <ul><li>3 </li></ul>1 2 4 Rock Identification is: 1 Conglomerate 2 Sandstone 3 Limestone - Biologic origin 4 Coal - Biologic origin
  9. 9. Metamorphic: Foliated vs Nonfoliated
  10. 10. Metamorphic: Foliated vs Nonfoliated Foliated - You can see mineral alignment and banding. Nonfoliated - cannot see any mineral alignment or banding
  11. 11. Metamorphic: Foliated vs Nonfoliated Mineral Identification: 1 Gneiss 2 Marble 1 2
  12. 12. The End
