Welcome to the virtual metamorphic rock ID lab. Please interact with the gigapans and 3D models & play around with the zoom to see what you can see.
Then answer the questions. There's lots to discover and use as scientific evidence to support your claims!
Be sure to use the Metamorphic Rock Types KEY to help you identify the rocks.
Metamorphic Rock Sample #1
Claim: What Type of Metamorphic Rock is this? Use your Metamorphic Rock ID Guide to help you.
Evidence: What evidence supports your claim?
Reasoning: What do these rocks tell you about the history of the region where they formed? Basically, what did these rocks USED to be before they were metamorphosed and what does that tell us about the past? (Was the area a river bank, lake/ocean deposits, igneous rocks, Earth's mantle, etc?)

Metamorphic Rock Sample #5
Claim: Based on our minerals lab last week, what might be a good way to test these rocks to see which one is quartzite and which one is Marble?

Quartzite is a metamorphic rock with the protolith being quartz sandstone. In quartzite, the quartz grains and silica cement of the original sandstone become fused and interlocking by the recrystallization process. Zoom in and note the cohesive fabric produced by the interlocking crystals of quartz. Credit: Callan Bentely, Mid-Atlantic Geo-Image Collection (M.A.G.I.C.) on GigaPan. CC BY Attribution 3.0

Marble is metamorphosed limestone (or dolostone) composed of calcite (or dolomite). Recrystallization typically generates visible interlocking crystals of calcite or dolomite.
