Why would hydrothermal metamorphism be common around igneous intrusions and active volcanoes?

The magma that forms an intrusion or feeds a volcano provides the heat that drives hydrothermal activity.

When Minerals that crystallize at high temperatures as a result of contact metamorphism tend to be found near?
Igneous Intrusions
Compare contact thermal metamorphism and regional dynothermal metamorphism and the types of rocks that result from each?
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.
What is the general term for igneous intrusions?
plutons
What do you call igneous rocks that have crystallized inside the Earth?

What can metamorphism do?
metamorphism is when a Igneous and sedimentary rocks turn into metamorphic rock.

What type of rock is formed around the outside of igneous intrusions?
Igneous rocks can be changed to sedimentary rocks outside of igneous intrusions. This is due to silt built up and weathering.

What is the largest of all igneous intrusions?
The largest of all igneous intrusions is called a batholith. Batholiths are formed by the massive invasion of hot magma into country rock.
When magma solidifies far belows earth's surface they form what?
When magma reaches the earth's surface, it is called lava. when it solidifies, it forms new crust, or rock.
How did you determine the sequence of the three igneous intrusions?
Igneous intrusions form when magma cools and solidifies before it reaches the surface. Three common types of intrusion are sills, dykes, and batholiths
Which two processes account for large deposits of important metals including ores of golamd silver and copper?
Igneous processes and hydrothermal solutions
What is regional and contact metamorphism?
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.
