Metamorphic Rock Examples
Quartzite
Tough building
material
Anthracite Coal
High quality,
creates lots of
energy when
burned
Metamorphic Rock: Marble
Metamorphic Rock: SlateUsed for: Billiards, chalkboards, roofs, floors
Metamorphic Rock Examples
GneissSchist
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
Metamorphic Rocks are Formed
from Parent Rocks
(Parent Rock)
Quartzite is the Metamorphic rock
Sandstone is the Parent Rock
Parent rock of Marble
Limestone Marble
Used For: Statues, buildings, countertops
Metamorphic Rocks are Formed
from Parent Rocks
Slate
Shale
Which specimen is the parent rock? Shale
Metamorphic Rocks are Formed
from Parent Rocks
Parent Rock The original rock material that forms metamorphic rock
Example:
Granite Gneiss
Metamorphic Textures 1. Foliated Rock
Bands of minerals in parallel layers
2. Non-foliated
Rock Without
bands
Foliated Metamorphic Rock
Examples:
Schist
Slate
Phyllite
Non-foliated Metamorphic Rock Examples:
Marble
Quartzite
Metamorphic Environments:Form where there is HEAT & PRESSURE
Magma and Friction make HEAT
Collisions and Gravity produce PRESSURE

smooth)

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