Proximity to a magmatic intrusion will cause metamorphosis in the country rock due to heat or hot fluids.
The heat that changes a rock into metamorphic rock comes from the Earth's internal heat, generated by processes like radioactive decay and pressure. This heat causes existing rocks to recrystallize and form new minerals, resulting in metamorphic rock.
What happens to cookie dough when you put it in the oven? The heat of the oven produces changes in the ingredients that make them interact and combine. Without melting the dough, the heat changes it into a whole new product - a cookie.
answ2. Rock may have its character changed by heat and pressure - the main components of metamorphism.
Marble is one of the low-grade metamorphic rocks, the limestone has become crystallized, but has obviously not been subject to sufficient heat to drive off the CO2.
High grade metamorphism is the name given to rocks that have had all of their original crystal structure and most of their chemical bonds changed.
In this process new minerals will be formed, minerals that were not present in the original rock.
Granites and their cousins the volcanic rocks illustrate the complete changes made to an original rock source. The new minerals present will indicate the maximum temperatures to which the rock has been exposed; and the last minerals to cool (those with a low freezing point) will indicate the age of the last cooling phase. This is inferred by radioactive tracer measurements, rather like C14 measurements.
Contact metamorphism occurs when rocks come in contact with molten magma far below the earths crust. hope this answer helped you :)

What is a protolith?
A protolith is the original rock from which a metamorphic rock is formed. It can be any type of rock, such as igneous, sedimentary, or another metamorphic rock, that undergoes changes in mineralogy, texture, or chemical composition due to heat, pressure, or fluids underground. The protolith provides the foundation for the new metamorphic rock's characteristics.
What rock is melted by heat and pressure?
Sedimentary rocks like shale, limestone, and sandstone can be melted by heat and pressure to form metamorphic rocks like marble, quartzite, and slate.
A rock body is exposed to large amounts of heat and pressure but does not melt and changes into a new type of rock. What is the new type of rock?
The rock would transform into a metamorphic rock. Metamorphic rocks are formed due to high heat and pressure without melting completely. Examples include marble, slate, and quartzite.
What changes igneous or sedimentary rock into metamorphic rock?
Igneous or sedimentary rocks are transformed into metamorphic rocks through high pressure, temperature, or both. This process, known as metamorphism, occurs deep within the Earth's crust where rocks are subjected to intense heat and pressure, causing their mineral composition and texture to change without melting.
Do the changes in rocks due to heat and pressure result in the formation of metamorphic rocks?
Yes, changes in rocks due to heat and pressure can result in the formation of metamorphic rocks. These changes can cause the minerals within the rock to recrystallize, realign, and form new mineral structures, giving rise to metamorphic rocks with distinct textures and compositions.
How do heat and pressure change sedimentary rock?
A metamorphic rock is formed when sedimentary rock is subjected to heat and pressure!
What changes a sedimentry rock into a metamorphic rock?
heat and pressure
What are some changes that occur when a sedimentary rock changes into a metamorphic rock?
To change a sedimentary rock to a metamorphic rock, you change it by time,heat, and pressure.
When heat and pressure changes a rock what kind of rock does it turn into?
metamorphic
How does metamorphic form?
Metamorphic rock is formed by heat and pressure making changes to igneous and sedimentary rock.
How Metamorphic rock form?
Metamorphic rock is formed by heat and pressure making changes to igneous and sedimentary rock.
What layer in the Earth changes sedimentary rock into metamorphic rock by heat and pressure?
heat and pressure
How does metamorphic rock chang into a sedimentary rock?
A sedimentary rock changes into a metamorphic rock when there is heat, pressure, and time. -over a long period of time
How do you change a igneous rock to a metamorphic rock?
you expose the rock to extreme heat or pressure such that the rock changes.
What forms as heat or pressure cause changes in an existing rock?
A "metamorphic" rock forms.
Where does the heat to form a metamorphic rock come from?
The heat comes from Earth's interior, which is always hot.
How does metamorphism rocks form?
metamorphic rocks are formed from sandstone
