The magma that forms an intrusion or feeds a volcano provides the heat that drives hydrothermal activity.
The four types of metamorphism are contact metamorphism, regional metamorphism, dynamic metamorphism, and hydrothermal metamorphism. Contact metamorphism occurs near igneous intrusions, regional metamorphism happens over large areas due to tectonic forces, dynamic metamorphism occurs along fault zones, and hydrothermal metamorphism involves hot, circulating fluids altering rocks.
Contact metamorphism occurs when rocks come into contact with high-temperature magma. Minerals formed under these conditions are typically found near igneous intrusions or volcanic activity, where the heat source is present. This can occur in areas such as volcanic regions, magmatic arc settings, or near igneous rock formations.
Marble is a nonfoliated rock that forms only in contact metamorphism. It is predominantly composed of the mineral calcite, which is recrystallized from limestone under high temperature and pressure near igneous intrusions.
Regional metamorphism is a widespread precess involving both heat and directed pressure, and is involved in things like mountain building and activity deep with in the core. Contact metamorphism is local processes involving low to moderate pressure and high temperature. This type is adjacent to igneous intrusion and along fractures in contact with hydrothermal (hot!) fluids at mid-ocean ridges.
The general term for igneous intrusions is "plutons". Plutons are bodies of intrusive igneous rock that form underground through the solidification of magma.

Igneous rocks can be changed to sedimentary rocks outside of igneous intrusions. This is due to silt built up and weathering.
The three main types of metamorphism are contact metamorphism, regional metamorphism, and dynamic metamorphism. Contact metamorphism occurs near igneous intrusions, regional metamorphism occurs over large areas due to tectonic forces, and dynamic metamorphism occurs along fault zones due to intense pressure and shearing.

Contact metamorphism occurs locally, next to igneous intrusions and along fractures that were in contact with hydrothermal fluids. Regional metamorphism occurs over very large areas, such as deep within the cores of rising mountain ranges, and generally occurs with the folding of rock layers. Both result in the formation of metamorphic rocks.
It forms deep inside the Earth's surface
Igneous intrusions form when magma cools and solidifies before it reaches the surface. Three common types of intrusion are sills, dykes, and batholiths
