F2.4 Metamorphic Rock Lab Problem: Which properties are used to identify metamorphic rocks?Background Information: ____________________ rocks are those that have been changed from an existing type of rock into a new type due to heat/pressure; most are formed deep within the EarthProcesses:_____________________ _____________________ - occurs when rocks are heated by contact with magma or lava_____________________ _____________________ - occurs over large areas when rocks buried deep beneath the earth’s surface are changed by increases in temperature and pressure (or when tectonic plates collide)Texture:__________________ - a type of metamorphic rock texture having mineral crystals arranged in parallel layers, or bands __________________ - a type of metamorphic rock texture that does not have bands of crystals and does break into layersWord Bank: regional metamorphism, metamorphic, non-foliated, contact metamorphism, foliatedHypothesis: If we look at the ____________________ and __________________ of the rock samples, then we will be able to determine its ___________________.Word Bank: process, origin, textureMaterials:Samples of metamorphic rocks Hand lensProcedures:Examine each of the rocks, observe their properties, and determine the type of metamorphic rock.Data:Rock #Texture:Grain Size(coarse, med. or fine)Bands, Layers orNo Layers?FoliatedorNon-foliated?Nameof Rock152153154155156SKIPSKIPSKIPSKIP157158159160Conclusions: Use complete sentences!What does the word metamorphosis mean in the actual dictionary?________________________________________________________________________________________________________________________________________________________What are the two major types of metamorphic processes that a rock can undergo?________________________________________________________________________________________________________________________________________________________What mineral is often found in schist?

List them by name.____________________________________________________________________________Which rocks are non-foliated? List them by name.____________________________________________________________________________Go back and look at every sample, even those you didn’t choose. One of the rocks has gemstones; which rock do you think it is based on the name? Explain your reasoning.________________________________________________________________________________________________________________________________________________________Go back and look at every sample, even those you didn’t choose. Which rock would make sense to use as a common building material? Explain.________________________________________________________________________________________________________________________________________________________If you were given a pile of rocks to identify, what is the main way to identify if a rock is metamorphic? What would you look for? Why?________________________________________________________________________________________________________________________________________________________ ................
