  1. ROCKS AND MINERALS HOW ROCKS FORM

  2. SCIENCE ROCKS!!!!

  3. MINERALS CHARACTERISTICS

  4. AMETHYST (QUARTZ) www.windows.ucar.edu/tour/link=/earth/geology/min_intro.html&edu=high

  5. Naturally occuring

  6. ROSE QUARTZ SMOKY QUARTZ WHITE QUARTZ www.windows.ucar.edu/tour/link=/earth/geology/mineral_id1.html&edu=hig

  7. Inorganic

  8. FOOLS GOLD IRON PYRITE www.windows.ucar.edu/tour/link=/earth/geology/min_types.html&edu=high

  9. Solid

  10. www.windows.ucar.edu/tour/link=/earth/geology/silicates2.html&edu=highwww.windows.ucar.edu/tour/link=/earth/geology/silicates2.html&edu=high

  11. Definite crystalline shape

  13. Definite chemical composition: 1 or more elements

  15. MOST COMMON MINERALS Silicates: 96% Carbonates Oxides

  20. ROCK Made up of 2 or more minerals

  21. IGNEOUS ROCK http://mineral.galleries.com/rocks/igneous.htm

  22. IGNEOUS ROCK

  23. SEDIMENTARY ROCK

  24. METAMORPHIC ROCK

  25. Which type of rock would have formed first on the original crust? • Igneous

  26. Examples: sand silt clay Examples: sandstone Shale limestone SEDIMENTARY ROCK Lithification (compaction & cementation) Sediments High Temperature High Pressure Weathering Erosion METAMORPHIC ROCK IGNEOUS ROCK Melting Examples: granite basalt pumice Examples: slate marble gniess quartzite Magma Cooling Crystallization

  27. ROCK CYCLE http://www.cotf.edu/ete/modules/msese/earthsysflr/rock.html

  28. In your own words, describe how each type of rock could turn into each of the other types of rock.

  29. shells deposition calcite lithification limestone High heat & pressure marble

  30. sand deposition silicate lithification sandstone High heat & pressure quartzite

  31. clay silt deposition silicate lithification shale High heat & pressure slate

  32. magma Cooling & Crystallization Mineral grains aligned in thick layers (foliation); less than 50% Granite High heat & pressure gneiss

  33. EXTRUSIVE (cools quickly) magma Cooling & Crystallization heat & pressure basalt green stone Cooling & Crystallization More heat & pressure Green schist Granite INTRUSIVE (cools slowly) High heat & pressure schist Mineral grains aligned into thin layers (foliation); 50% or more
