Metamorphic Rocks
Sedimentary Rock Quiz tomorrow ! (Half Period Quiz)

2. Aim: What environmental factors are needed to form a metamorphic rock?
Do Now: What do you think the word metamorphism means?

3. Metamorphism To Change Form 2 types of metamorphism
Regional and Contact

4. Where does metamorphism usually take place?
Areas of INTENSE HEAT AND PRESSURE

5. Contact Metamorphism Hot magma moves into rock LOW GRADE Example:
Limestone  Marble

6. Regional Metamorphism
Occurs during mountain-building
HIGH GRADE
Example:
ShaleGneiss

7. Agents of Metamorphism
HEAT AND PRESSURE
Both heat and pressure
INCREASE with depth

9. Heat
Heat drives RECRYSTALLIZATION
(Creates new minerals)

10. Pressure Tends to create new minerals
Forms bands because of MINERAL ALIGNMENT

11. Classification (Page 7 ESRT)
Foliated and Nonfoliated Rocks

13. Foliated
Layered or Banded Appearance

14. Nonfoliated Rocks Does not have a banded texture
Most nonfoliated metamorphic rocks contain only one mineral
Quartzite
Metaconglomerate
