Question
II- List the factors that control metamorphism: 1. Indicate which of the following statements is true (T) and which is false (F). Correct every false statement 1) Inherited textures are best preserved in high grade metamorphic rocks 2) A metamorphic aurcole is a product of contact metamorphism The best index minerals are ones that typically have relatively large stability fields in pressure- temperature space. 3) 4) A quartzite is a metamorphosed granite 5) Blueschists and eclogites form at divergent plate boundaries. 6) Greenschists are high grade metamorphic rocks.Explanation / Answer
Metamorphism is the process by which composition, structure of a rock is changed by the actions of heat, pressure or other natural agency.
Factors controlling metamorphism:
1) The temperature at which metamorphism takes place.
2) The amount and type of pressure.
3) Types of fluids that are present.
4) Time available
5) Mineral composition of parent rock.
