Metamorphic Rock Analysis and Interpretation
Develop your ability to describe and interpret textural and compositional features of metamorphic rocks.
- Analyze the samples of sedimentary limestone and metamorphic marble
- What is the mineral? What test could you perform on the rocks to be sure?
- How do the textures of these two rocks differ, if at all?
- Describe the difference in grain size from slate to schist.
- How does the texture of phyllite differ from that of schist, if at all?
- Why do you think that the (flat minerals) in these rocks are all parallel, or nearly so, to one another?
- Describe a process that could account for how this strong, dense gneiss was folded without breaking during regional metamorphism.
