One is high and one is low.
The levels of metamorphism are low-grade, medium-grade, and high-grade. These levels are based on the temperature, pressure, and chemical changes that rocks undergo during metamorphism. Low-grade metamorphism occurs at lower temperatures and pressures, while high-grade metamorphism occurs at higher temperatures and pressures.
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.
Yes, kyanite is often considered an index mineral of low-grade metamorphism because its formation is indicative of high pressure and moderate temperature conditions. Its presence can help geologists determine the degree of metamorphism a rock has experienced.
Granulite forms at the highest grade of regional metamorphism. It is a high-grade metamorphic rock primarily composed of minerals such as pyroxene and plagioclase feldspar. Granulite typically forms under high temperatures and pressures deep within the Earth's crust.
Soapstone forms through regional metamorphism, which occurs over large areas and at high pressures and temperatures. It is mainly composed of talc, which forms from the metamorphism of magnesium-rich rocks like peridotite or serpentinite.

high grade metamorphism can progress to pressure and weather.

Yes, slate is a type of foliated metamorphic rock that forms from the low-grade metamorphism of shale or mudstone. It typically displays a fine-grained texture and excellent cleavage, making it valuable for use in roofing and flooring due to its durability and resistance to weathering. Slate commonly forms under moderate temperatures and pressures, distinguishing it from rocks formed under high-grade metamorphism.
Metamorphic rock can undergo a series of changes called degrees of metamorphism, from low-grade to high-grade.
Extreme pressure and temperatures, such as those found at the base of a thickened crust.

Sillimanite is an index mineral for high temperature and variable pressure metamorphism.
Granulite forms at the highest grade of regional metamorphism. It is a high-grade metamorphic rock primarily composed of minerals such as pyroxene and plagioclase feldspar. Granulite typically forms under high temperatures and pressures deep within the Earth's crust.
