Metamorphic Rocks

1. Sort the words into the correct category depending on whether they describe igneous or metamorphic rocks. METAMORPHIC ROCKS foliation mineral alignment banding unmelted recrystallization formed from heat and pressure IGNEOUS ROCKS melted magma and lava glassy texture intergrown mineral crystals formed from melting, cooling, and solidification of lava vesicular texture (gas pockets) 2. What type of rock is this? igneous sedimentary metamorphic 3. What visible characteristic can you see in this rock that allows you to determine the rock type? fossils banding vesicular texture (gas pockets) glassy texture 4. What can you see in this rock that tells you what type of rock you are looking at? glassy texture fossils distortion shells Use the "Scheme for Metamorphic Rock Identification" below to answer questions 5 through 10. 5. Use the "Scheme for Metamorphic Rock Identification" above to answer the following question: Wavy bands of light and dark minerals visible in gneiss bedrock probably formed from the cementing together of individual mineral grains cooling and crystallization of magma evaporation of an ancient ocean heat and pressure during metamorphism 6. Use the "Scheme for Metamorphic Rock Identification" above to answer the following question: Which physical characteristic best describes the rock phyllite? glassy texture with gas pockets clastic texture with angular fragments bioclastic texture with cemented shell fragments foliated texture with microscopic mica crystals 7. Use the "Scheme for Metamorphic Rock Identification" above to answer the following question: Which rock is foliated, shows mineral alignment but not banding, and contains medium-sized grains of quartz and pyroxene? phyllite schist gneiss quartzite 8. Use the "Scheme for Metamorphic Rock Identification" above to answer the following question: Which rock would most likely be produced by the metamorphism of limestone? quartzite slate marble gneiss 9. Use the "Scheme for Metamorphic Rock Identification" above to answer the following question: How does the metamorphic rock schist differ from the metamorphic rock quartzite? 10. A B C D
