No. It has a much higher melting temperature because it is more difficult for it to expand due to the increased pressure at depth.
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.
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.
The decomposition process of a buried snake can vary depending on factors like environmental conditions, temperature, and soil type. In general, it can take several weeks to a few months for a snake to fully decompose underground.
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.

Sedimentary rocks can turn into metamorphic rocks after being buried deep within the Earth's crust. The increased pressure and temperature caused by burial can change the mineral composition, texture, and structure of the rocks, transforming them into a new type of rock.

Melt and recrystallize
Prograde metamorphism refers to metamorphic processes that occur as rock is buried deeper in the Earth's crust and experiences increasing temperature and pressure. This leads to changes in mineral composition and texture as the rock undergoes metamorphism.
The pressure and temperature increase, possibly causing the rock to undergo metamorphism. This can change its mineral composition, texture, and structure. The rock may also experience deformation and recrystallization as a result of tectonic forces.
Yes, sediments buried 3 to 4 km deep experience temperatures and pressures that can trigger chemical and mineral changes leading to cementation. This process involves the precipitation of minerals, like quartz or calcite, in the pore spaces between sediment grains, binding them together to form rock. The increased temperature and pressure at such depths can facilitate this cementation process.
Burial metamorphism refers to the alteration of rocks due to increased pressure and temperature from the weight of overlying sediment. This type of metamorphism occurs at relatively low temperatures and pressures compared to other types, such as regional metamorphism. It commonly occurs in sedimentary rocks buried deep within the Earth's crust.
