In geology, exhumation is the process by which a parcel of buried rock approaches Earth's surface. [1]It differs from the related ideas of rock uplift and surface uplift in that it is explicitly measured relative to the surface of the Earth, rather than with reference to some absolute reference frame, such as the Earth's geoid.
The displacement of rocks with respect to the surface is called exhumation. This simple equation relates the three kinds of displacement: Surface uplift = uplift of rock – exhumation. The term geoid is used above to mean mean sea level and makes a good frame of reference. A given displacement within this frame of reference allows one to ...
Tectonic Burial is the deformation of rocks caused by extreme pressure over millions of years. [1] It often causes temperature evolutions and deep burials. [2] Tectonic burial is usually the result of continental collisions or subduction in a region. [3]
Finally, the continuous drop in pressure and temperature in 1800 Ma resulted from further erosion and exhumation. The peak pressure is found to be reached before the peak temperature, owing to the relatively poor thermal conductivity of the rock upon increasing P-T condition, while the rock instantaneously experienced the pressure changes.
Formation of a metamorphic core complex. Metamorphic core complexes are exposed areas of deep crust brought to the surface by crustal extension (stretching). [1] They form, and are exhumed, through relatively fast [citation needed] transport of middle and lower continental crust to the Earth's surface [2] in the form of uplifting welts of hot rock and magma.
