If exposed to high enough temperatures and pressures, long-buried igneous rocks can undergo metamorphism, transforming into metamorphic rocks. This process alters the mineral composition and texture of the original rock, often resulting in the formation of foliation or new mineral assemblages. The resulting metamorphic rocks can exhibit characteristics such as increased density and hardness, depending on the specific conditions of temperature and pressure. Examples include the transformation of granite into gneiss or basalt into amphibolite.

When long-buried igneous rock is exposed to high temperatures and pressures, it can undergo a process called metamorphism. This transformation alters the mineral composition and texture of the rock without melting it, resulting in a metamorphic rock. The heat and pressure can cause recrystallization of minerals, foliation, and the development of new minerals, depending on the original rock type and the specific conditions of metamorphism. If the temperatures become extreme enough, the rock may eventually melt and form magma.
If exposed to high enough temperatures and pressures, long-buried igneous rock could undergo metamorphism, transforming into a metamorphic rock. This process involves the recrystallization of minerals and the alteration of the rock's texture and composition without melting. The resulting metamorphic rock may exhibit new characteristics, such as increased density and the formation of foliation or banding, depending on the conditions of pressure and temperature.
Yes, when long-buried igneous rock is exposed to high temperatures and pressures, it can undergo metamorphism, leading to the formation of new minerals. Erosion can also wear away overlying materials, revealing the rock beneath. Additionally, if the conditions are extreme enough, the rock may partially melt and then recrystallize, resulting in a different type of igneous or metamorphic rock. This dynamic process illustrates the continuous rock cycle in geology.

Melt and recrystallize
Igneous rocks, specifically those that are formed from the cooling and solidification of magma, can melt back into lava or magma when subjected to high temperatures and pressure. Additionally, sedimentary rocks can also melt into magma if they are buried deep within the Earth's crust and exposed to extreme heat. Metamorphic rocks, formed under heat and pressure from existing rocks, can similarly melt into magma under sufficient conditions.
How are igneous rocks destroyed? - Quora. Igneous rocks are either ground to sand by erosion or buried under heat and pressure, converted into metamorphic rocks. ... Finally, they can just sit there, buried but too near the surface to face any significant heat or pressure, for a very long time.
Metamorphic rocks are formed underground through the process of heat and pressure altering existing rocks. When rocks are buried deep in the Earth's crust, they are subjected to high temperatures and pressures that cause their mineral composition and texture to change. This results in the formation of metamorphic rocks from pre-existing igneous, sedimentary, or other metamorphic rocks.
If a metamorphic rock is buried deeply in the earths' crust it comes under great pressures and temperatures. If these are great enough to re-melt the rock it ceases to be metamorphic and when it cools, it re-crystallizes into an igneous rock.
Sedimentary rock can be turned into lave or magma by contact with either of the substances or exposure to extreme heat. When the lava or magma cools, it becomes igneous rock.Students who are using wiki.answers.com could be advised that copying word for word is plagerizm.
Coal forms from the decomposition of plant material over millions of years under high pressure and heat. Oil is formed from the remains of marine plants and animals that are buried and exposed to high temperatures and pressure. Natural gas is produced in a similar way to oil but at higher temperatures and pressures, usually from more mature organic material.
