Rocks metamorphic 2 1321570180

Metamorphic Rock Examples

Quartzite

Anthracite Coal

Tough building
material

High quality, creates
lots of energy when
burned


Metamorphic Rock: Marble


Metamorphic Rock: Slate

Used for: Billiards, chalkboards, roofs, floors


Metamorphic Rock Examples

Schist

Gneiss


Metamorphic

 “meta”
meta = to change
 “morph”
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
Quartzite is the
Metamorphic
rock

(Parent 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
Phyllite

Slate


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

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


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


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


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
