Textbook Question
Chapter 25, Problem 20RQ
Distinguish between foliated and nonfoliated metamorphic rocks.
Expert Solution & Answer
To determine
The difference between foliated and nonfoliated metamorphic rocks.
Answer to Problem 20RQ
The foliated rocks have a layered appearance, whereas nonfoliated metamorphic rocks have a uniform appearance.
Explanation of Solution
The difference between foliation rocks and Nonfoliated rocks are shown below:
Foliation rocks | Nonfoliated rocks | |
---|---|---|
1 | Foliation rocks have a layered appearance which occurs when rocks are under high pressure. | Nonfoliated rocks show uniform appearance. |
2 | Foliation is developed due to high pressure and temperature both.Both are necessary | Nonfoliated rocks can form either due to high pressure or high temperature. |
3 | Examples are granite, quartz and feldspar. | Examples are marble and quartzite. |
Conclusion:
Therefore, the foliated rocks have a layered appearance whereas nonfoliated metamorphic rocks have a uniform appearance.
