1. Metamorphic Rocks

2. Metamorphic Rock Examples
Anthracite Coal
High quality, creates lots of energy when burned
Quartzite
Tough building material

3. Metamorphic Rock: Marble

4. Metamorphic Rock: Slate
Used for: Billiards, chalkboards, roofs, floors

5. Metamorphic Rock Examples
Gneiss
Schist

6. Metamorphic “meta” = to change “morph” = form
Metamorphic rocks are formed from Parent rocks (pre-existing rocks)
Parent rocks can be Igneous, sedimentary, or other metamorphic rocks.
Metamorphism The process through which a rock’s structure is changed by heat and pressure

7. Metamorphic Rocks are Formed from Parent Rocks
Quartzite is the Metamorphic rock
Sandstone is the Parent Rock
(Parent Rock)

8.  Parent rock of Marble Limestone Marble
Used For: Statues, buildings, countertops

9. Metamorphic Rocks are Formed from Parent Rocks
Slate
Shale
Which specimen is the parent rock?
Shale

10. Metamorphic Rocks are Formed from Parent Rocks
Parent Rock  The original rock material that forms metamorphic rock
Example: 
Gneiss
Granite

11. 2. Non-foliated Rock  Without bands
Metamorphic Textures
1. Foliated Rock  Bands of minerals in parallel layers
2. Non-foliated Rock  Without bands

12. Foliated Metamorphic Rock Examples:
Schist
Phyllite
Slate

13. Non-foliated Metamorphic Rock Examples:
Marble 
Quartzite 

14. Metamorphic Environments:
Form where there is HEAT & PRESSURE
Magma and Friction make HEAT
Collisions and Gravity produce PRESSURE

15. Metamorphic Cheer M-E-T-A MET-A-MORPH-IC Heat and Pressure
Heat, Heat, and PRESSURE
Go…… FOLIATION

16. METAMORPHIC ROCK TEXTURES Foliated (mineral bands)
Non-foliated (no bands, grainy or smooth)

17. METAMORPHIC ROCK PARENT ROCKS Sandstone  Quartzite Limestone  Marble
Shale  Slate
Granite  Gneiss

18. METAMORPHIC ROCK META = CHANGE MORPH = FORM
Metamorphism involves the change in form or structure of a rock through heat and pressure.

19. 3 ROCK TYPES:
Igneous-formed from the cooling and crystalization of magma
Sedimentary-formed by the compacting and cementation of layers of sediment
Metamorphic-formed by structural/chemical change due to heat and pressure

20. Metamorphic Rock Lab Set up your field notebook (Include Title)
Rotate independently between the 16 stations set up around the room
Start with whichever station number you are located
Round 1: You will have 1 minute at each station
Do not switch to the next station until told to do so
Round 2: You may go back to any unoccupied station, if needed
