Temperature
What is the lower limit of temperature for metamorphism, considering the original protolith?
150±50 °C
At what pressure and in the presence of what fluid do granites begin to melt?
5 kbar and presence of aqueous fluid
What is the process of extensive chemical changes during metamorphic transformation known as?
Metasomatism
What are the limits of temperature for metamorphism?
Lower limit (150±50 °C), higher limit (beginning of melting, 650-1100 °C)
Test your knowledge of metamorphic rocks and the process of metamorphism with this quiz. Explore the extensive chemical changes that occur during this transformation and demonstrate your understanding of mineralogy and texture changes in solid state. Ideal for Grade 12 STEM students studying geology in the 2023/2024 school year.
