Metamorphic Rock Examples Quartzite Anthracite Coal Tough building

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 § Limestone § Shale § Granite Quartzite Marble Slate 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
