  1. In nature things move violently to their placeand quietly in their place. - Francis BasonIntrusive rocks Lecture 6 Webpage for course (daytime) Webpage for course (nighttime)

  2. long cooling time allows crystals to grow larger Intrusive (plutonic) rocks pluton

  3. Pluton: large intrusive igneous rock body can take a variety of shape and sizes massive tabular

  4. Tabular plutons, two general types D I S C O R D A N T CONCORDANT

  5. D I S C O R D A N T Tabular plutons, two general types CONCORDANT Example: sill Example: dike

  6. Massive plutons, two general types Bathylith (“deep rock”) > 100 square km stocks < 100 square km

  7. Associated with modern magma chambers - geysers - hot springs “Old Faithful” Yellowstone N. P. Fig. 10.18

  8. “Old Faithful” http://www.nps.gov/archive/yell/tours/livecams/oldfaithful/images/oldfaithfulbehivelabeled.jpg&imgrefurl=http://www.nps.gov/archive/yell/tours/livecams/oldfaithful/oldfaithfulphoto.htm&usg

  9. What causes a geyser?

  10. Geothermal Energy

  11. Geothermal Energy Advantages • Disadvantages Need Shallow Magma chamber Inexpensive (after initial cost) Long lasting Low environmental cost

  12. Why not use the magma chamber below Old Faithful?

  13. “Geothermal Energy” - ground – based heat pumps

  14. (still have time??) The metric system!

  15. Why metric? Convenience Accuracy Economy
