Rockcyc Mineral Rockcyc Mineral Presentation Transcript

  • The Rock Cycle Thinking about relationships among the major rock groups
  • Major Rock Groups
    • Igneous
      • Formed from a melt (molten rock)
      • Plutonic (intrusive):slow cooling and crystallization
      • Volcanic (extrusion): quick cooling at the surface
    • Sedimentary
      • Formed at the Earth’s surface
      • Clastic (Mineral Fragments or grains, clays)
      • Chemical (crystalline chemical/biochemical precipitates)
    • Metamorphic
      • Changed by pressure, temperature and fluids.

    • The rock cycle demonstrates the relationships among the three major rock groups
    • It is powered by the interior heat of the Earth
    • As well as earth’s momentum and…
    • The energy from the sun
    • It involves processes on the Earth’s surface as well as the Earth’s interior
    • It connects the “hydrologic cycle” with the “tectonic cycle”.
  •  
  • What is a mineral?
    • Naturally occurring
    • Non-organic
    • Characteristic chemical composition
    • Distinctive physical properties
    • Crystalline structure
  • Mineral properties
    • Color
    • Luster
    • Habit (Shape)
    • Cleavage & Fracture
    • Streak
    • Hardness
    • Other
  • Color:
    • Not mineral specific
  • Luster: How minerals reflect light Non-metallic Metallic
  • Mineral Habit (Shape)
    • Shape a mineral takes if grown unimpeded
  • Cleavage & Fracture
    • Cleavage: planes of weakness along which minerals can break
    • Fracture: surfaces along which minerals can break
  • Cleavage & Fracture Best identified on a fracture surface
  • Streak:
    • The powdered form of a mineral
  • Hardness:
    • Based on Moh’s scale of hardness
  • Other Properties
    • Specific gravity
    • Reaction to acid
    • Striations
    • Magnetism
  • Igneous Rocks
  • Metamorphic Rocks Gneiss Schist
  • Sedimentary Rocks Shale Conglomerate Sandstone
