Metamorphic Rock Hand Samples

Metamorphic Rocks:Use the hand samples on the lab tables and the slides presented in class yesterday to answer these questions IMPORTANT: read these instructions before answering questions1. Using the hand samples and yesterday's slides, match one parent rock to each of the metamorphic rocks. Place the parent rock in the box next to the metamorphic rock.2. Match one mineral (and wood) to each pair of metatmorphic and parent rocks.3. Match the parent rocks and minerals on this worksheet AFTER you finish doing it by hand.EXAMPLE: One pairing has been done for you. The parent rock for schist is slate, and the mineral biotite mica gives it its thin foliation. Slate Shale or mudstone Schist Slate Gneiss Granite Quartzite Quartz Sandstone Marble Limestone Anthracite Coal Bituminous Coal Minerals in metamorphic rocks Match the metamorphic rock to the minerals listed below AFTER you finish doing it by hand.EXAMPLE: One pairing has been done for you. The parent rock for schist is slate, and the mineral biotite mica gives it its thin foliation. Slate muscovite mica Schist biotite mica Gneiss potassium feldspar Quartzite quartz Marble calcite Anthracite Coal wood Select one metamorphic rock. How can you tell what it's parent rock was? Answer using a complete sentence, and you must describe an observation you can make in class. Do not say "the notes told me so".EXAMPLE: The schist and slate have a similar foliation, but the micas have grown larger in the schist since it is a higher grade metamorphic rock. Select one metamorphic rock. How can you tell what mineral it is composed of? Answer using a complete sentence, and you must describe an observation you can make in class. Do not say "the notes told me so".EXAMPLE: The schist contains crystals of a flat, black mineral that cleaves in one direction, just like biotite mica. What happened to the fossil shells in the limestone when it was metamorphosed? the shells grew larger the shells were weathered away the shells dissolved and were replaced with a completely different mineral the calcite in the shells was recrystallized
