The high grade metamorphism refers to the metamorphism that takes place at temperatures that are greater than 320 degree Celsius. The high grade metamorphism also takes place at relatively high pressure.

What is the difference between low grade and high grade metamorphism?
One is high and one is low.
Is Kyanite is an index mineral of a low grade metamorphism?
No, kyanite is an indicator of high pressure metamorphism.
Which kind metamorphic rock most likely form in the high temperatures and pressures?
At the highest temperatures and pressures, high-grade metamorphism occurs forming high-grade metamorphic rocks. The main example of this is gneiss.
What are the Levels of metamorphism?
Metamorphic rock is given a grade from low to high depending on the amount of change it has undergone.
What are the three main types of metamorphism Compare and contrast the factors that cause each type?
The three main types of metamorphism are: Regional Metamorphism Contact Metamorphism Hydrothermal metamorphism Regional metamorphism is caused when high temperature and pressure affect large regions of Earths crust, It can range from low grade to high grade. It causes folded rock layers. Contact Metamorphism is when molten material comes in contact with solid rock. High temperature and moderate to low pressure from mineral assemblages. Metamorphic effects decrease with distance. Hydrothermal Metamorphism is when very hot water reacts with rock and alters its chemical and mineral composition. As hot fluids migrate in and out of the rock during metamorphism the original mineral composition and texture of the rock change.
Slate is associated with high-grade metamorphism?
No Slate is associated with a low-grade metamorphism
What can high grade metamorphic progress to?
high grade metamorphism can progress to pressure and weather.
What is the difference between low grade and high grade metamorphism?
One is high and one is low.
Is Kyanite is an index mineral of a low grade metamorphism?
No, kyanite is an indicator of high pressure metamorphism.

Does metamorphic rock change?
Metamorphic rock can undergo a series of changes called degrees of metamorphism, from low-grade to high-grade.
What are the Levels of metamorphism?
Metamorphic rock is given a grade from low to high depending on the amount of change it has undergone.
What produces high grade metamorphism?
Extreme pressure and temperatures, such as those found at the base of a thickened crust.

What metamorphic grade does the mineral sillimanite belong to?
Sillimanite is an index mineral for high temperature and variable pressure metamorphism.
