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” = 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 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 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 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
