'The higher the pressure, the greater the degree of metamorphism.' refers to the relationship between pressure and:
Degree of metamorphism
What is the main geological process responsible for the formation of tectonic pressure?
Regional metamorphism
At what temperature range does low-grade metamorphism take place?
200 - 320C
What type of metamorphism is commonly associated with convergent plate boundaries?
Regional metamorphism
Which type of rock texture is most often formed from mudstones and contains fine-grain minerals?
Foliated
What is the composition of a chemically active fluid involved in metamorphic processes?
Mostly water with dissolved ions
What is the main difference between foliated and non-foliated metamorphic rocks?
Foliated rocks have evidence of planar fabric, while non-foliated rocks do not.
Which geological process causes contact metamorphism?
Magma intrusion into existing rock
Which geological process is associated with the formation of mid-ocean ridges?
Sea floor spreading
What is the primary factor that increases the rate of metamorphic reactions?
Increase in temperature
Explore the different types of metamorphism including low P/T series, medium P/T series, and high P/T series, each forming specific mineral facies under certain pressure and temperature conditions. Learn about contact metamorphism and hydrothermal metamorphism within the low P/T series.
