Does the sample appear to be mostly or entirely composed of the same mineral? Is the rock layered (foliated)? Are the foliations planar or folded? Are different layers composed of different colors/types of mineral? Are some mineral grains large and others much smaller? Is there any hint of shiny mica minerals along the foliations?

Lab 7 Metamorphic Rocks, Processes, and Resources

Analyze the metamorphic rocks in Fig. A7.1.1 and actual rock samples of them, if available. Beneath or beside each picture, briefly note the most distinctive features you observe in the rock.

For example, does the sample appear to be mostly or entirely composed of the same mineral? Is the rock layered (foliated)? Are the foliations planar or folded? Are different layers composed of different colors/types of mineral? Are some mineral grains large and others much smaller? Is there any hint of shiny mica minerals along the foliations?

B REFLECT & DISCUSS Reflect on your observations and descriptions of metamorphic rocks in part A. Then describe

How you would classify the rocks into groups. Be prepared to discuss your classification with your classmates or teacher.
