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

TEXTURES

Non-foliated (no bands, grainy or

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
