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  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 Cheer M-E-T-A MET-A-MORPH-IC Heat and Pressure Heat, Heat, and PRESSURE Go…… FOLIATION 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 minute at each station  Do not switch to the next station until told to so  Round 2: You may go back to any unoccupied station, if needed [...].. .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 Cheer...
