Most metamorphism takes place deep underground, where high heat and pressure change the rocks, since both increase with depth.
Metamorphism can occur through contact metamorphism, where rocks are altered by heat from nearby magma; regional metamorphism, where rocks are subjected to high pressure and temperature over a large area; burial metamorphism, where rocks are subjected to increased pressure from being buried deep underground; and dynamic metamorphism, where rocks are deformed under high pressure but low temperature conditions along faults or shear zones.
Subduction and high pressure.
The metamorphism caused by extreme heat and pressure is known as regional metamorphism. When a meteorite collides with the Earth, it can create impact metamorphism in the surrounding rocks, characterized by high pressures and temperatures from the impact event.
Two processes that can cause metamorphism are heat (from deep burial or nearby magma) and pressure (from burial or tectonic forces). These processes can change the mineralogy, texture, and sometimes the chemical composition of rocks, leading to the formation of metamorphic rocks.

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.
High temperature and high pressure.
high grade metamorphism can progress to pressure and weather.

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.
Subduction and high pressure.
Metamorphism involves the combination of high temperature and pressure acting on the existing rock to change its mineral composition and texture. These conditions can alter the rock without completely melting it, leading to the formation of metamorphic rocks.
