Metamorphic Rock Examples Quartzite Tough building material Anthracite Coal High quality, creates lots of energy when burned

Marble Metamorphic Rock: Marble

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

Metamorphic Rock Examples Gneiss Schist

Metamorphic meta  “meta” = to change morph  “morph” = form Parent rocks  Metamorphic rocks are formed from Parent rocks (pre-existing rocks) Igneous, sedimentary, or other metamorphic  Parent rocks can be Igneous, sedimentary, or other metamorphic rocks. heat and pressure  Metamorphism  The process through which a rock’s structure is changed by heat and pressure meta  “meta” = to change morph  “morph” = form Parent rocks  Metamorphic rocks are formed from Parent rocks (pre-existing rocks) Igneous, sedimentary, or other metamorphic  Parent rocks can be Igneous, sedimentary, or other metamorphic rocks. heat and pressure  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

Metamorphic Rocks are Formed from Parent Rocks  Parent Rock  The original rock material that forms metamorphic rock  Example:  Parent Rock  The original rock material that forms metamorphic rock  Example:  GraniteGranite GneissGneiss

Metamorphic Textures  1. Foliated Rock  Bands of minerals in parallel layers  2. Non-foliated Rock  Without bands

Foliated Metamorphic Rock Examples: SchistSchist SlateSlate PhyllitePhyllite

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

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