Metamorphic Rock Examples

Quartzite

Tough building

material

Anthracite Coal

High quality, creates lots of energy when burned

Metamorphic Rock: Marble Marble

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

Metamorphic Rock Examples

Gneiss Schist

 “ meta” = to change meta

 “ morph” = form morph

 Metamorphic rocks are formed from

Parent rocks

Parent rocks (pre-existing rocks)

 Parent rocks can be Igneous, sedimentary,

or other metamorphic 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:

Metamorphic Environments:

Form where there is HEAT & PRESSURE

Magma and Friction make HEAT

Collisions and Gravity produce PRESSURE

Metamorphic Cheer

Heat and Pressure

Heat, Heat, and PRESSURE Go…… FOLIATION

METAMORPHIC ROCK

 Foliated (mineral bands)

 Non-foliated (no bands, grainy or

smooth)

METAMORPHIC ROCK

 PARENT ROCKS

METAMORPHIC ROCK

 META = CHANGE

 MORPH = FORM

 Metamorphism involves the

change in form or structure of a rock through heat and pressure.

3 ROCK TYPES:

and crystalization of magma

 Sedimentary-formed by the

compacting and cementation of

layers of sediment

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
