The document discusses metamorphic rocks, which are formed from pre-existing rocks through heat, pressure, and chemical reactions typically near tectonic plate boundaries. Metamorphism can change a rock's appearance, texture, mineral content, and crystal structure, forming either foliated or non-foliated rocks. Examples of foliated metamorphic rocks include schist, slate, and gneiss, while examples of non-foliated rocks include marble and quartzite.

1. Meta=change
Morphic=form/shap
e

2. I. Parent Rocks
Rocks that
have been
changed
from an
original
“parent”
rock

5. II. How are Metamorphic
Rocks Formed?
 Formed under tremendous heat, great
pressure, and chemical reactions
 Can make new minerals
 Most are found on or near plate
boundaries
 Metamorphism is changing one type of
rock into another as a result of
heat(from mantle), Pressure (from
layers above) and/or chemical
reactions.

7. III. Where does the Heat Come
From?
The heat comes
from:
1. Mantle
2. Pressure of the
layers
3. Movement of the
Plates on Earth

9. IV. What does Metamorphism
change?
 Metamorphic rocks
can change:
1. a rocks
appearance, texture
2. crystal structure
3. mineral content
 It can form from a/an:
1. Igneous
2. Sedimentary
3. Another
metamorphic rock!

10. a. Foliated – mineral crystals are
arranged in parallel layers or
bands
Examples: Schist, slate, and gneiss
b. Nonfoliated – rocks are not banded
and do not break into layers
Examples: Marble and quartizite
V. Types of Metamorphic
Rocks

12. Foliated

13. Non-foliated
NON-Foliated

14. VI. Contact vs. Regional
Metamorphism

construction of
buildings and
walkways
Used in tables,
floors, and
roofing
