Question
![A Analyze the samples of sedimentary limestone and metamorphic marble in Fig. A7.3.1.
1. These rocks are both composed of the same mineral. What is it?
What test could you perform on the rocks to be sure?
2. How is the texture of these two rocks different?

limestone
marble
Figure A7.3.1
B Figure A7.3.2 shows three metamorphic rocks that had a mudstone or shale protolith and that display excellent foliation.
The three specimens represent different metamorphic grades. Higher-grade types can also be formed from protoliths
other than mudstone, but we are going to think about a progression from mudstone through successively more intense
metamorphism.
1. Describe the change in grain size from slate to schist.
2. How does the texture of phyllite differ from that of schist?
3. Why do you think that the micas (flat minerals) in these rocks are all parallel, or nearly so, to one another?
slate
phyllite
schist
