Bural metamorphism occurs when hot magma or lava comes in contact with rock?

No. This is contatc metamorphism. Burial metamorphism occurs when rock is altered due to the weight of overlying rock.


When hot fluids migrate into and out of a rock during metamorphism what will change?

grade


What changes when hot fluids migrating into and out of a rock during metamorphism?

grade


What rock forming process occures when hot magma forces its way into rock?

contact metamorphism


How do ores form from contact metamorphism?

When Hot Magma comes into contact with existing rock.


What are the three main types of metamorphism Compare and contrast the factors that cause each type?

The three main types of metamorphism are: Regional Metamorphism Contact Metamorphism Hydrothermal metamorphism Regional metamorphism is caused when high temperature and pressure affect large regions of Earths crust, It can range from low grade to high grade. It causes folded rock layers. Contact Metamorphism is when molten material comes in contact with solid rock. High temperature and moderate to low pressure from mineral assemblages. Metamorphic effects decrease with distance. Hydrothermal Metamorphism is when very hot water reacts with rock and alters its chemical and mineral composition. As hot fluids migrate in and out of the rock during metamorphism the original mineral composition and texture of the rock change.


How are contact and hydrothermal metamorphism different from each other?

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.


How does hot fluid change the mineral composition of a rock during metamorphism?

Hot fluid dissolves materials and adds other materials :)


What is different between metamorphism and metasomatism?

Metasomatism is specifically the chemical change of rock by the introduction of hot fluids, creating a different type of rock.Broadly, metamorphism is the change of rock from one type to another by heat and/or pressure.


Where is the dynamic metamorphism located?

Contact metamorphism is defined as metamorphism in which the mineralogy and texture of a body of rock are changed by exposure to the pressure and extreme temperature associated with a body of intruding magma. It can either happen deep underground or at the Earth's surface.


How do the effects of contact metamorphism compare with those of regional metamorphism?

contact and regional metamorphic are similar because both of them happen cause of hot heat and pressure which make the rock metamorphic


What type of rock would result from the metamorphism of granite?

Granite is Igneous rock. It crystallizes from hot melt (magma). Metamorphic rocks can be found associated with granite as result of their contact with country (surrounding) rocks. This will be a contact metamorphism. Metamorphism of granite it self results into granitic gneisses which are coarse foliated rocks.
