    Igneous, Sedimentary, and Metamorphic Rocks Igneous, Sedimentary, and Metamorphic Rocks Presentation Transcript

    • Igneous, Sedimentary, and Metamorphic Rocks Chapter 5 & 6 P Squires 2005-2006
    •  
    • What are igneous rocks?
      • Rocks formed from crystallization
      • of magma.
    • Types of Igneous Rocks
      • Extrusive – fine grained and quickly cooled.
      • Intrusive – coarse grained and slowly cooled.
    • Composed of Magma
    • Magma Elements
      • Oxygen
      • Silicon
      • Aluminum
      • Iron
      • Magnesium
      • Calcium
      • Potassium
      • Sodium
    •  
    •  
    • Bowen’s Reaction Series
      • Illustration of the relationship between cooling magma and mineral formation.
      • Feldspar – undergoes continuous change.
      • Iron-Rich Minerals – undergo abrupt change.
    •  
    • Layered Intrusions
    • Classification of Igneous Rocks
      • Mineral Composition
      • Grain Size
      • Texture

    • Sedimentary
      • Sediments – pieces of solid material that have been deposited on the Earth’s surface by
          • Wind
          • Water
          • Ice
          • Gravity
          • Precipitation
    • Weathering
      • Where surface is being worn away
      • Breaks rocks into smaller pieces
      • Produces clastic (broken) rocks
    •  
    • Erosion and Transport
      • Rocks are then transported to new locations
      • Surface material is removed (erosion)
    • Deposition
      • When sediments are laid down on the ground or found in the bottom of bodies of water.
      • Some are sorted, but some are not
      • How would they be sorted?
    • Deposition
    • Lithification
      • Processes that transform sediments into sedimentary rocks.
      • What is cementation?
    • Lithification
    • Clastic sedimentary rocks
      • Coarse-Grained Clastic
      • Medium-Grained Clastic
      • Fine-Grained Clastic
    • Rocks formed from Evaporation
    • Metamorphic Rocks
      • When rocks don’t meet the magma stage, they become metamorphic rocks.
      • Combinations of temperature and pressure form different kinds of metamorphic rocks.
    • Foliated Metamorphic Rocks
    • Foliated Metamorphic Rocks Wavy layers Bands
    • Non-foliated Metamorphic Rock
    • Non-foliated Metamorphic Rock
    • Rock Cycle
