Hydrothermal metamorphism is a type of metamorphism that occurs when rocks come into contact with hot, aqueous fluids. These fluids cause changes in the mineralogical and textural properties of the rocks, ultimately leading to the formation of new minerals. Hydrothermal metamorphism commonly occurs in areas with active tectonic processes, such as mid-ocean ridges and subduction zones.
Hydrothermal processes are responsible for creating ore bodies at divergent plate boundaries. When water interacts with hot rocks, it dissolves minerals and can concentrate them in fractures and openings, forming valuable ore deposits. This process occurs in hydrothermal vents along mid-ocean ridges where new oceanic crust is forming.
Hydrothermal fluids or metamorphic fluids can introduce new elements into the rock, altering its overall composition during metamorphism. These fluids can transport ions like silica, aluminum, potassium, and others, leading to the growth of new minerals and changing the rock's composition.

contact metamorphism, regional metamorphism, dynamic metamorphism
Metamorphic rocks at hot spots will form mostly by contact and hydrothermal metamorphism as a result of exposure to heat from magma and interaction with hot water respectively.
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.

There different from each other because contact metamorphism is a local effect that occurs when molten rock meets solid rock, but on the other hand hydrothermal metamorphism occurs when very hot water reacts with rock, altering its mineralogy and chemistry.
Hydrothermal processes are responsible for creating ore bodies at divergent plate boundaries. When water interacts with hot rocks, it dissolves minerals and can concentrate them in fractures and openings, forming valuable ore deposits. This process occurs in hydrothermal vents along mid-ocean ridges where new oceanic crust is forming.
Hydrothermal fluids are a common agent of metamorphism that can cause the overall composition of a rock to change. These fluids can introduce new minerals into the rock through chemical reactions, altering its composition and structure.
Talc is formed by the hydrothermal alteration of ultrabasic rocks, or low grade thermal metamorphism of siliceous dolomites.
Hydrothermal fluids or metamorphic fluids can introduce new elements into the rock, altering its overall composition during metamorphism. These fluids can transport ions like silica, aluminum, potassium, and others, leading to the growth of new minerals and changing the rock's composition.
Types of metamorphism are Contact Metamorphism Regional Metamorphism Cataclastic Metamorphism Hydrothermal Metamorphism Burial Metamorphism Shock Metamorphism (Impact Metamorphism)
The three agents of metamorphism are heat, pressure, and chemically active fluids. Heat is responsible for increasing temperature, pressure for increasing stress and confining pressure, and chemically active fluids for introducing new minerals through the process of metamorphism.
Hydrothermal metamorphism occurs around igneous intrusions and active volcanoes because the heat and fluids associated with magma bodies provide ideal conditions for mineral alteration and growth. As magma intrudes into the crust, it heats up the surrounding rock and releases fluids rich in dissolved minerals. These fluids interact with the host rock, leading to the formation of new mineral assemblages through hydrothermal alteration processes.
