This document provides information about metamorphic rocks, including examples such as quartzite, anthracite coal, marble, and slate. It explains that metamorphic rocks form from existing parent rocks through heat and pressure in metamorphic environments. Metamorphic rocks can have foliated textures with mineral bands or be non-foliated without bands. Common parent rocks include sandstone forming quartzite, limestone forming marble, and shale forming slate. The document also gives examples of metamorphic textures and environments.

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

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
(Parent Rock)
Quartzite is the
Metamorphic
rock
Sandstone
is the 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:

Granite Gneiss

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

12. Foliated Metamorphic Rock
Examples:
Schist
Slate
Phyllite

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, 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
